Our Roots
Our Roots
The production facility erected
by the company in 1999 provides ultra-modern development
workplaces for applied microelectronics and fine mechanics and
a very well equipped production
location with modern machine
park and production technologies
to satisfy the requirements placed
on rational series production and
customised equipment construction.
The hall extension building realised in 2001 provides additional
production space for the production and assembly of large volume
lysimeter container stations and
for apparatus building so as to
satisfy the growing demand for
these test equipment set-ups.
Umwelt - Geräte - Technik GmbH
The production location was supplemented in 2003 by an outdoor
Our roots - the Berlin / Brandenburg location
The research city of Müncheberg
looks back on a long and significant tradition in the area of
agricultural sciences and is wellknown for its research institutes
both nationally and internationally.
Established as the Kaiser-WilhelmInstitut für Züchtungsforschung
in 1928 under the management
of Prof. Dr. Erwin Baur, the foundation stone was laid for intensive agricultural and agronomic
research in Müncheberg, which
was most successful particularly
in plant cultivation up to the end
of the 2nd World War.
The research activities were resumed on re-opening under the
name of the Zentralforschungsanstalt für Pflanzenzucht (ErwinBaur-Institut) on 1 October 1945,
and the research institute continued in 1952 as the Institut für
Acker- und Pflanzenbau of the
German Academy of Agricultural
Sciences in Berlin.
4
In 1970 the working area of the institute was extended as a research
centre for soil fertility of the Academy of Agricultural Sciences of
the GDR.
After the reunification of Germany on 2 January 1992, the
research facility with an initial
8 institutes took up its work as
Zentrum für Agrarlandschaftsund
Landnutzungsforschung
(ZALF) e.V. and has worked as
member of the Leibniz Community since 2005 as Leibniz-Zentrum
für
Agrarlandschaftsforschung
Müncheberg in research on ecosystems in agricultural landscapes
and the development of ecologically and economically acceptable
land use systems.
Foundation of UGT GmbH
On 2 May 1992, Umwelt-GeräteTechnik GmbH (UGT) took up
operations as a spin-off from
ZALF e.V. From the first hour, the
company founders and employees of Umwelt-Geräte-Technik
GmbH worked for many years in
different areas of the Forschungszentrum für Bodenfruchtbarkeit
Müncheberg at a scientific and
technical level.
Carried by the expertise of the
shareholders, an interdisciplinary
high-performance team of scientists, engineers and technicians is
now available.
Our employees have worked for
many years in a scientific capacity in the areas of hydrology, soil
physics, geoecology and geography, biology and the construction
of scientific aparatus and equipment. Solid expertise, coupled
with extensive experimental experience in the laboratory and in
the field form the foundation for
developing and producing environmental instrument technology
with high innovative character,
high quality and highly usable products.
Umwelt-Geräte-Technik GmbH
test area with integrated 4-fold
lysimeter station, a weather station and a soil hydrological measurement site.
One year later, a well equipped
soil laboratory was inaugurated
and an ongoing ground water
observation point set up.
These facilities are used to conduct project work and to verify
measurement methods and environmental measurement devices
from the company‘s own development and production.
On 15 September 2008 the UGT
GmbH south branch was founded
in the Munich conurbation and
premises rented in the innovation
and founder centre of FreisingWeihenstephan. In addition to
office space, the exhibition and
conference areas enable UGT
GmbH to show its complete performance range.
A new electronic laboratory was
set up in 2009.
These grounds are at the same
time a test location to conduct
soil re-cultivation processes of a
former site of the steel and coal
industry. The basis for the tests
is provided by a technically well
equipped large-scale lysimeter
installation which was erected by
UGT GmbH in France.
UGT is committed to the long
tradition of the research location
Müncheberg and as an employer
UGT serves to the people of our
region. With the success on the
national and international market
there we secure and create new
jobs. With the doubling of the
production area in 2016 we achieved better working conditions and
can manufacture large PE-HD lysimeter stations in-house. We dispose of specially equipped rooms
for producing micro-electronics
and micro-system technology.
With the new production hall
with a total area of 900m², UGT
has in 2017 a productive area of
1800m². The course for the future
of the company has been set, the
team works continuously with the
view to the future.
1992 Founding of the UGT GmbH
On 2 January 2010 the service center UGT GmbH - France, was opened in Homècourt (Lothringen)
which is located on the grounds
of the Industrial Association GISFI.

Our Services
Training
Lysimeter cutting
Our team of scientists and technicians provide training and induction for practical use under field
and laboratory conditions for all
products of UGT GmbH.
We can provide you with soil monoliths at a broad variety of locations for your lysimeter or column
experiments.
Training events range from service, calibration and measurement instruction through to
plausibility checks and the interpretation of the data records obtained. Thanks to our cooperation
partners, we are able to offer this
training also internationally - in
Brazil, Australia, China and Russia,
for example. Specialised papers
on new measurement methods
and instrument developments are
given in national and international
workshops as well as ideas and
experience exchanged.
Planning and installation
We offer scientifically based project advice for the erection of
measurement stations and lysimeter installations. UGT GmbH is
happy to assume the conception
and design of the measurement
project equipment, construction
realisation, installation and test
run as well as instruction or maintenance or to support you according to your requirements.
6
We have the technology to provide you with monoliths with diameters of 100 mm to 500 mm in
lengths of up to 1.0 m as well as
large volume soil monoliths with
cross section areas of 0.5, 1.0 and
2.0 m² and lengths of up to 3 m.
We will also be happy to advise
you on the selection of the suitable monoliths for your research.
More detailed information on our
patented methods as well as the
possible dimensions of the soil
columns may be found in the “Lysimeter technology” chapter starting on page 193.
Lysimeter retrieval
After completion of the lysimeter experiments we are happy to
retrieve the lysimeters for you.
Using a special lysimeter retrieval
technique, the soil monolith is cut
into different thicknesses whilst
maintaining the full cross sectional area. The use of high speed
diamond cable sawing technology enables the original structure
of the monoliths to be essentially
maintained.
Additional tests on soil development in the lysimeters as well as
chemical and biological analyses
of the soil cores are facilitated
here. After securing these additional results, the lysimeter vessels
are available for the production
of new soil monoliths. The PEHD container lysimeter stations
we offer can also be used again
after retrieval. They may be repositioned as required and equipped
with new lysimeter vessels.
Lysimeter experiments
In our own lysimeter station,
which essentially serves to verify
new measurement methods and
components, we offer the possibility of conducting special lysimeter experiments for you. Test
runs with different objectives can
be made simultaneously on four
Lysimeters with a cross-section
area of 1.0 m² and a height of 2.0
m. Due to the direct proximity to
the lysimeter, our employees are
in an ideal position to accompany
the project. We can conduct data
collection and the complete analysis of the experiment for you or
together with you.
Determining hydrological soil ratios
Maintenance and service
Project support
In our soil laboratory, we determine the following hydrological soil
ratios using lysimeter samples:
We offer maintenance and service for the test setups and instruments installed by us as well
as inspections to guarantee long
term perfect function. During this
work, readjustments and calibration work is performed as well as
function checks and in particular
estimates made for the normal
useful life of field installation.
We are able to guarantee an optimum service due to our knowledge of the installations and our
many years of experience with
the measurement equipment. We
offer plant specific maintenance
contracts for monitoring stations.
We can support you in your project
in the development of measurement equipment and procedures
or in the design of new measurement stations or networks. From
development through production
to installation and test run, UGT
GmbH offers the support of the
individual steps and of the entire

Customisations
Pump for the automated sampling of printer ink
Obtaining water samples in a gas-tight bag
Our customisations
In order to do justice to the varied
requirements placed on environmental measurement technology and to provide you with the
most suitable equipment for your
research, we also produce customised special solutions, not only
in the area of environmental measurement technology. We are also
happy to provide our technical
know how for the development
and production of new instruments and apparatus.
For example, in accordance
with the suction probe method
we have developed a pump for
the automated taking of printer ink samples for the company Vistaprint. The vacuum unit
consists of 5 independent pump
units, the ON period of which and
vacuum may be set individually
for each of the 5 units. The samples are filled in boro-silicate glass
flasks with drain taps. In cooperation with the Landeskontrollverband Brandenburg e.V. a sampler
has been developed to take silage
samples in order to monitor their
quality. Unlike the usual samplers,
the silage sampler from UGT can
be driven into the silage using little force and retrieved again.
A special plate tensiometer has
been developed for experiments
8
on the influence of wind erosion
on fields at the Institute of Plants
and Nutrition and Soil Science of
the Christian-Albrechts University
of Kiel. Instead of using a ceramic
cup, the tension is transferred via
a ceramic plate. This enables the
tension of the above soil layer to
be recorded. This tensiometer
was installed in a wind tunnel in
order to determine the correlation between soil moisture tension
and soil erosion.
We also convert new technologies
into handy measurement instruments. For example, the procedure developed by the BGD Bodenund Grundwasserlabor GmbH
Dresden to obtain representative
seep water samples using suction
cups and a gas-tight bag from UGT
has been converted to a sampling
system.
The suction cups with a P80
ceramic cell remain permanently
installed in the soil. Instead of a
collection volume, they have an
open shaft into which a cartridge
is inserted for sampling which
docks onto the suction cup. There
is a gas-tight sampling bag in the
cartridge which is connected with
the ceramic cup when docked.
Applying a vacuum to the pressure-tight cartridge outside the
sampling bag causes water with
all the dissolved gases and volatile substances in the water to be
drawn from the suction cup into
the sampling bag. The gas-tight
bag is the sample transport vessel
from which the samples are taken
in the laboratory for the individual
analyses. For repeated sampling
the bag in the cartridge can be
changed and substances for the
conditioning of the seep water
sample provided.
A further advantage of the system
is that the volatile gas elements of
the water sample can be collected
in the gas-tight bag and analysed
in the laboratory. The seep water
collector with gas-tight bag has already been successfully used for
the seep water forecast and landfill monitoring and will soon supplement our constantly growing
product range.
Please consult us for specific
inquiries on customisations
and for innovative ideas.

Soil drilling and sampling
Soil drilling and sampling permits an insight into the structure of the soil.
The horizontalisation of the soil, which already provides information on
internal soil processes such as substance relocation, can be determined
directly by visual means. Using soil samples the physical and chemical soil
parameters to determine properties such as pore volume or hydraulic conductivity can be obtained in laboratory tests. A large number of different
drilling devices and soil sample rings have been developed to cater to the
different soils and the specific requirements placed on the samples. Corresponding accessories make the hard work of sampling easier and improve
the quality of the samples.

Taking undisturbed samples from sample ring samples
Soil sample rings
Soil sample rings are used to take soil samples which are as undisturbed
as possible for laboratory research such as to determine the pore volume,
the hydraulic or pneumatic conductivity or water content. The hollow rings
made of stainless steel have a cutting edge on one side. With this cutting
edge facing down, they are pressed or hammered into the ground. The soil
volume in the inside of the soil sample ring is remove with the soil sample
ring and remains in it until investigated in the laboratory. The soil sample
ring itself as well as lid on the top and bottom sides enclose the sample
completely. This enables it to be transported practically and without disturbances. The soil samples with soil sample ring are removed quickly, easily
and the samples obtained in this manner are essentially undisturbed. A
further advantage is that a uniform volume is always taken from the soil
with the same type of soil sample ring.
Undisturbed sampling with sample ring
Based on the patented UGT sampling method for large soil monoliths, UGT GmbH has developed
this sampling device for soil samples with a sample ring size of 120
mm diameter and 120 mm height.
Equivalent to the excavation technology for large soil monoliths
the soil is pre-cut to minimise the
forces impacting on the soil. The
sample ring is firmly positioned
in a stainless steel cutting sleeve
studded with cutters. This cutting
sleeve is driven by an electrical
motor via a planetary gear so that
the sample ring inside remains
perfectly still while the cutting
sleeve rotates to pre-cut the soil
sample. The sample ring can then
take in the detached soil sample
accurately to shape.
The cutter unit and drive are
mounted on a portable tripod
which is vertically aligned and
fixed in the ground at the sampling point. The large pneumatic
tyres on the tripod permit a high
degree of mobility in the field and
therefore simple access to the
sample points.
An external power supply is required to operate the electrical motor. Appropriate generating units
can be procured from UGT if required.
Both stainless steel and plexiglass
sample rings with the corresponding size can be used with this
sampling device. Plexiglass sample rings enable subsequent computer tomographic examination
and provide a visual impression

justable. Therefore the sampling
point can be freely chosen on
the surface of the 120 mm sample ring. The cutting sleeves are
manually pressed in using a crank
handle. In the cutting process, the
sample is pressed out of the large
sample ring from below by a die
and pressed into the small sample rings. Thus the soil outside the
small sample ring can expand and
distortions caused by pressure on
the small samples are prevented.

Hammering head for soil sample rings
The hammering head is an attachment used to hammer soil sample rings into harder soils with a
hammer. The impact is distributed
evenly over the complete edge of
the soil sample ring. The hitting
edge is also somewhat deeper
and there are pressure compensation bore holes in the base plate
of the hammering head. This per-
of the soil. For plexiglasscylinders
a stainless steel cutting ring is put
on to support the cutting effect.
Advantages
Technical data
With this sampling device, undisturbed samples with Ø = 30 mm
can be excavated from 120 mm
sample rings for higher resolution soil examinations in the lab.
Amongst others, this enables examinations of the mesopores and
the root distribution. Up to three
30 mm samples can be obtained
simultaneously from one layer of
the sample ring.
The Plexiglass sample rings are
placed in stainless steel cutting
sleeves which pre-cut the soil
before it is taken in the sample
rings. The position of the cutting
sleeves on their support is ad-
•Minimal influence of bedding
•Sample excavation irrespective

mits disturbances to the soil sample taken to be minimised. The
hammering head is available for
UGT soil sample rings with a volume of 100 cm³ and 250 cm³.
A polyamide impact hammer is
also available.
Soil sampler
Using the soil sampler, soil sample
rings can be pressed into soft or
medium hard soils without a hammer. It consists of a handle piece
which is connected tightly with a
ring holder using a bayonet connection. The soil samples may be
taken both vertically from the soil
surface and horizontally to a soil
profile.
The soil sampler is suitable for UGT soil sample rings with a volume of
100 cm³ and 250 cm³.

Ergonomic auger set
Hand auger equipment
Hand auger equipment is available in different sets and also as individually
compiled components and are made of a specially hardened high quality steel. Deeper drillings may be made by extensions with a bayonet connection or with a conical screw thread. A drilling depth of around 8 to 10
m may be achieved using hand auger equipment. The maximum drilling
depth will depend on several factors including soil structure and properties
of the material to be drilled.
The ergonomic hand auger set for
heterogenous soils is used to carry out manual drilling and sampling in a great variety of different
soils in an ergonomically sound
manner. It is particularly suitable
for general soil investigation (description of the layering, geology,
mineralogy) and for environmental research.
Almost every soil type places special requirements on the model of the
auger to be used. This is why several models have been developed during
the course of a year which have been ideally designed for the specific requirements.
Hand auger types
•Edelman auger (in different versions for clay, sand and coarse sand)
•Riverside auger (hard, stiff soils mixed with fine gravel)
•Stony soil augers (for soils with a high gravel content)
•Spiral augers (to drill through hard horizons/layers, e.g. local stone)
•Stone catchers (to remove loose stones from the auger hole)
•Augers for soft soil
•Piston samplers (for less cohesive, wet soil layers beneath the ground water)
Connections
Bayonet connection
Auger set for heterogenous soils
Drilling and sampling in homogenous soils (soils with a uniform soil
profile) can in almost all cases be
executed with one type of auger.
For drillings in heterogenous soils,
several different auger types will
be applied. With the standard set
it is possible to execute manual
drilling to a depth of 5 m without
great physical effort. The standard
set comprises different auger types, diameter 7 cm so that this
set can be used successfully with
all drillings in layered soil profiles.
The set can be used for drilling
above the water table in all soils,
and below the water table in cohesive soils. The piston sampler
is used for looser soils also below
the ground water table.
The advantages of the bayonet connection are rapid assembly
and low weight.
One disadvantage that only leads to problems for certain tasks
is that the connection is without play. The bayonet connection
is used as the standard connection.
The auger set (with bayonet connection) comprises the following
items among others: four types
of Edelmann augers (clay, combination, sand, and coarse sand), a
riverside auger, a stony soil auger,
a spiral auger, a piston sampler
and a gouge auger.
The set also includes the following:
Extensions, line search probe,
submersible bell with tape measure, a pull and push piece, care
material and a field map. This is all
provided in an aluminium transport case.
This set is available both with bayonet connections or with conical
screw thread connection!
Conical thread connection
The connection consists of an inner and outer thread and the
parts to be connected. If the connection is tightened a strong
join is made.

Universal gouge auger - PÜRCKHAUER
Gouge augers
Hand operated equipment can be used for soil research up to a depth of
5 to 10 m. A number of augers are described in this section. Their common denominator is that they are all fitted with an almost half cylindrical
operational part with parallel cutting edges running vertically, justifying the
name gouge auger. The operational part may vary in length as well as diameter. The most suitable length depends on the penetration resistance,
the substance of the soil and required drilling depth. The longer the operational part, the more vulnerable the auger is to torsion. The selection of the
most suitable diameter will depend on the composition and the structure
of the soil and on the purpose of the research. In general a smaller diameter is used in soils with a fine and/or dense structure than in soils with
a loose structure (e.g. young swampy soils).
Advantages
The advantages of gouge augers compared to other hand auger equipment are
as follows:
•A large profile overview per sample taken, due to the very long effective auger
body.
•A large drilling area per hole so that large drilling depths can be quickly
reached.
Areas of use
Due to the fact that the samples show very little disturbance, these gouge augers
are frequently used for investigations for the following purposes:
•Mapping
•Soil suitability investigations
•Training
•Root investigations
•Fertiliser investigations
•Clay classification
•Palaeontological investigations
Groove auger
The groove auger is used to take
soil samples and investigate the
soil horizons. Under consideration
of the different soil properties we
offer this auger in two different
versions.
The groove auger for heavy soil is
particularly strong and torsion resistant. The core volume consists
of a groove with a diameter of
12 mm which is laterally milled
into the solid rod made of steel
with special alloy.
22
The length of the groove is 1000 mm.
The groove auger for light soils
consists of a special steel tube
with a diameter of 30 mm and
wall thickness of 4 mm which is
open at the sides. The groove of
1000 mm length has a diameter of
22 mm in this version.
The shaft can be extended up to
4 m using 1 m screw on pieces.
Advantages
•Favourably priced
•Tough
•Simple to use

Universal gauge augers particularly suitable for very hard and stony
soils. A set with a gouge auger of
the type PÜRCKHAUER with hammer and mechanical withdrawal
system as well as accessories packaged in a strong carry case.
Bi-partite gouge augers
The bi-partite gouge augers can
be extended by coupling an extension rod. In this way, drillings may
be made very quickly and greater
depths can be reached.
A set with conical thread con-
nection for the sampling from

Göttinger gouge auger
The Göttinger gouge augers have
been developed for taking soil
samples up to 90 cm depth, and
are primarily designed for soil
sample removal with N-min tests.
The sampling is done by hand
without the use of tools such as
hammers or hooks.
The drill groove is manufactured
from specially hardened steel
adapted to the strong load, so
that it is as thin as possible while
still being robust and elastic.
The sophisticated milled profile of
the drill groove and the system of
three drills matched in diameter
minimizes the frictional force for
pressing into and pulling out of
the soil.
This permits sampling using less
force compared to conventional
sampling equipment.
The Göttinger gouge auger set
consist of three drilling rods
(0-30 cm, 30-60 cm and 60-90
cm).
Gouge auger set for stepwise sampling
The set consists of three bi-partite
gouge augers with different diameters. By first taking a sample
with the gouge with the largest
diameter and subsequently the
gouges having smaller diameters,
cross contamination among the
samples is avoided. The gouge augers can be pushed into the soil or
www.ugt-online.de
hammered (with an impact absorbing hammer).
Because of the short operational
length and the diminishing diameters, the set is very suitable for
profile research (nitro research)
in soils with a somewhat higher
penetration resistance.

Root sampler
The root sampler has been specially designed for forest soils. The
sampler itself consists of two half
shells with a smooth cutting ring
and a clamp flange which guarantees a tight connection of the two
halves during drilling. To insert
the sampler into the soil and to
retrieve it easily, a head with cross
borehole is screwed on for the insertion of a lever or lifter. During
drilling the sampler as a full tube
is particularly stable and the facility to open up one side of the tube
provides easy access to the drilled
core.
tube with a window permitting a
view of the profile of the sampled
core.
The standard version of the root
sampler is made of rust free V2A
steel, is 600 mm long and has a
diameter of 80 mm. At customer
request, the geometric dimensions can be altered and adapted to
the specific uses.
Advantages
•Suitable for forest soils rich in roots
•Very tough

The solid tip with centering pushes the soil away when the probe is inserted into it. Turning the
probe causes the sample to be cut
from the substrate whilst at the
same time the metal sheet closes
the sampling vessel. After a half
turn around the auger axis (180°)
the sample vessel is full.
The metal plate remains in this
position due to its own resistance
and therefore completely closes
the sampling vessel. This can now
be pulled from the soil and the
sample withdrawn.
The length of the sampling vessel is 500 mm, producing a sample volume of approx 0.5 l with
an inner diameter of 60 mm. The
overall length of the moor probe
is 1000 mm. Either a turn handle
or extensions can be attached directly to this. Grips and extensions
with spring connectors are provided for fast assembly/dismantling. The standard set contains 10
extension pieces each of 1 m in
length.
On request, sets may also be compiled with the customised number
of extensions.

Tensiometers
The soil moisture tension is the foundation for every water movement and
therefore for every water balance analysis. The gradient of the soil moisture tension determines both the direction and the speed of the water
movement.
The soil moisture tension can be recorded using tensiometers by water in
the tensiometer being connected with the pore system of the soil via a
porous ceramic cup. The pressure relationships are transferred to the pressure sensor inside the tensiometer. Thereby it must be pointed out that the
soil moisture tension is defined as a negative prssure. According to this underpreeure in the pores implies a positive soil moisture tension. Impounding causes negative tension valves. A large variety of versions permits the
use of tensiometers for a broad range of tasks.
This applies from the ring soil sample in the laboratory through to field use
and from short term measurements through to long term monitoring.
All tensiometers are supplied filled and ready to use.

Tensio 120
Tensio 100
Mobile field tensiometer
The Tensio 100 is the root of the
UGT-tensiometer technology and
has been continuously developed
further over more than25 years.
It is a cost-efficient tensiometer
type that is especially designed for
the easy and fast mobile measurement of the suction in the field.
The Tensio 100-set comprises a
V2A-insertion auger for quick installation, as well as a protective
tube for transport, in which the
tensiometer is kept permanently
moist for immediate use and is
protected from mechanical damage. In the tensiometer head made
of transparent acrylic glass air inclusions are easily recognizable.
The pre-tensioning screw enables
an easy refilling even in the field.
Additionally this screw allows to
preset a tension to reduce the
measurement time to less than
Septum tensiometer
3 seconds per measurement
(from installation to reading).
The Septum tensiometer permits several tensiometers to be
read out using only one instrument and therefore offers a favourably priced alternative to the
comprehensive determination of
soil moisture tension with many
measurement points. The top
side of the tensiometer is sealed
with a silicone septum so that
The measurement corpus itself is
made of a V2A-standpipe (Ø 10
mm), a Ms support, a ceramic cell
(SKA 100FF, 10x24 mm) and a V2A
tip. Depending on the type of Tensio 100 the suction pressure is displayed on a mechanical precision
vacuum meter (Ø 63 mm) or via
an electronic pressure transducer
on a handheld or a laptop.
the hand meter can be attached
quickly and simply with a needle.
The septum recloses automatically when the meter is removed.
It can be replaced simply because
it is screwed on using a GL18 thread or used as a silicon plug depending on design. The ceramic
cup (P80; 20 x 50 mm) is mounted on a transparent acrylic tube
(Ø 20 mm) with level scale. It is
therefore easy to read the level of
the tensiometer.

The pressure transducer tensiometer offers an ideal combination
of the simple handling of the mobile field tensiometer with electronic data acquisition. As for the
Tensio 100 field tensiometers, the
measurement system consists of
a V2A standpipe (Ø 10 mm) and
V2A insertion tool, an Ms support
unit and a ceramic cell (SKA 100FF,
10x24 mm).
The Tensio 152 is especially developed for challenging applications.
The used stainless steel membrane sensor is more durable and
more resistant against aggressive
media. The Tensio 152 is therefore
particularly suitable for contaminated and extremely saline soils.
When installed, the Tensio 152 is
also frost protected because the
pressure transducer is situated
directly above the ceramic cup
and the water tank is therefore
exclusively at installation depth.
The plastic standpipe (PVC Ø = 25
mm) minimises temperature conduction from colder layers of soil.
The Tensio 152 freezes with the
ground when installed in soil layers near to the surface, but on
thawing is immediately functional
again and continues the measurement. This means that it can be
used throughout the year and for
long-term monitoring of the soil
moisture tension.

Watermark
Soil moisture sensor
The measurement principle of the
Watermark sensors is similar to
that of plaster blocks. However,
the special sensor does not dissolve in the soil and has a more
even distribution of pores so that
more precise measurements are
possible.
The sensors are permanently buried in the soil and have an
average serviceable life of 3 to
5 years. They do not need any
service work during this time and
are frost-proof. The Watermark
sensors are available with temperature sensors whose values may
be used for temperature compensation. This method of soil moisture tension measurement may
be used as a substitute for tensiometers if it is to be expected that
the tensiometer will frequently
fall dry at the installation site. The
sensors may be connected either
to a data logger or to the speci-
fic hand instrument for recording
and reading out the data.
Advantages
•No maintenance
•Winter-proof
•Good suitability for long term
measurements
•Price efficient
The Full Range Tensiometer by
UGT covers the complete range
of water potentials relevant for
plants, even up to 1500 kPa depending on the model. Unlike
other systems with an according
measurement range the Full Range Tensiometer doesn‘t determine the tension as an indirect
measurement derived from another measured parameter but as
a direct pressure measurement.
Changes in tension are transmitted very fast. A range of 1000 kPa
is passed through within some
minutes. Even after complete drying and leaving the measurement
range the measurement is automatically continued as soon as
the soil moisture increases again.
Refilling is not necessary. Another
advantage compared with other
instruments for the complete
plant relevant tension range is
the low energy consumption (20
mA in operational mode). Therefore the Full Range Tensiometer
is particularly suitable for remote
measurement sites where regular
maintenance and reliable supply
of electricity cannot be ensured.
The data transmission via RS485
allows communication even in environments with increased risk of
electromagnetic interference and
over greater distances .
The measurement is reliable also
in difficult media. Saline sites, as
may occur in aride climates, are
no problem as a result of the direct pressure measurement.
The temperature is recorded as an
additional parameter.

Soil moisture meters
Soil moisture is a determining factor for plant growth. It is therefore of great
significance from the point of view both of agriculture and environmental
protection. It influences chemical processes in the soil and therefore the
formation of soil itself as well as the spread of pollution and contaminants.
The measurement of soil moisture permits the determination of favourable and unfavourable plant locations, the recognition of changes in the
ecological systems and statements to be made about important soil and
water balance processes. The control of soil moisture, for example for agricultural irrigation, can be optimised and automated by way of permanently
monitoring soil moisture.
The easy-to-install field meters determine the soil moisture indirectly via
relating soil properties. From this relating properties subsequently the meter calculates the soil moisture. These sensors facilitate permanent monitoring and the electronic recording of measurement values by a logger.

UMP-1 COMBINED SOIL MOISTURE, CONDUCTIVITY AND TEMPERATURE SENSOR
UM
P-1
The UMP-1 series provides a range of combined sensors that offer high
quality measurements with minimum effort.
Combining the three measurement variables of volumetric water content,
electrical conductivity and temperature in a single sensor means that these
combination sensors save money spent on acquisition and save time spent
on installation and servicing. Disruption to the soil is also minimised because only one sensor needs to be inserted.
Various possibilities for data storage and transmission are available depending on the planned measuring arrangement.
The measurement principle of measuring the water content is closed to the
FDR procedure, because the sensor operates with an contionuous signal
at constant frequency (60 MHz). The signal propagates into the medium
and is partially reflected. Compared with the original the phase shifting of
the reflected signal is considered. The size of the shift is a measure for the
permittivity εr and the water content of the soil.
UMP-1 BT
The UMP-1 BT sensor is the wireless version of the UMP-1 sensors and opens up the market to
smartphone-based measurement
technology. Measurement data
are transmitted by Bluetooth directly to and stored on an Android smartphone. The necessary
app can be downloaded from the
Google Play Store and installed by
the user on any Android smart-
phone. Up to 7 probes can be managed simultaneously using the
app, and measurement data can
be stored and visualised. During
measurement, the data can be
depicted as graph or as table of
readings. Further it is possible to
link the measurement data to the
location of the measurement site
if the smartphone features GPS.
Advantages
Technical data
•Measurement frequency for water content:
60 MHz (other frequencies on request)
•Antenna length: 100 mm (other lengths on request)
•Antenna diameter:

The standard version of the UMP-1
sensor is designed for connection
to a data logger via cable.
Data are stored on the data logger, and are read out via an interface cable on a laptop or via data
transmission.
The UMP-1 BTim is the compact
version of the UMP-1 BT sensor. It
consists of a shaft with the integrated UMP-1 BT sensor, a heightadjustable handgrip, a smartphone holder and a spring guide for
inserting the measuring rods. This
device has all possible advantages
to fast and easy carry out measuring campaigns with lots of single
measurements, distributed over
large areas. The rods are more stable with a bigger diameter compared to the standard version.
The rods are inserted into the soil
This design is especially suitable
for measurement stations with
several sensors and long-term
measurements such as soil hydrological measurement stations or
lysimeters.
with pressure. They are protected
by a spiral spring and a guide at
the bottom of the shaft. The shaft
together with the hand grip and
the smartphone holder facilitate
the handling, enabling many point
measurements in a shorter time.
The UMP-1 BTim sensor has an integrated battery. It is switched on
for each measurement and switched off again. The supply voltage
is recorded additionally. Thus, it is
possible to charge the battery in
time preventing data loss.

UMP-1 BT Plus
The UMP-1 BT Plus is the advanced version of the UMP-1 BT sensor. Data are transmitted via Bluetooth to any windows-PC and can
be visualized and managed with
the application software. Additionally this sensor features an integrated data logger and can therefore be used autonomously. The PC
or laptop is only needed to read
SMT-100
data and to start, stop and manage a measurement.
They are therefore also suitable for longer-term deployments,
especially as stand-alone sensors
independent of complete measurement stations. Since the sensor
can be completely burried the
UMP-1 BT Plus is also very easy to
protect from vandalism.

The three models of the UMP-1
are sealed to make them waterproof, and can also be completely
buried. An installation depth of
50 cm should not be exceeded for
the two wireless types of sensor
so as to guarantee data transmission via Bluetooth. The energy
supply to the wired UMP-1 sensor is provided via the electricity
supply cable on the data logger.
Wireless sensors have an integrated storage battery whose charge
lasts for 6 to 24 months depending on the measurement intervals and the frequency of reading
out data. The sensor reads out the
water content of the soil in % volumetric water content. However
the εr value can be retrieved for
independent water content calculations according to other models.
The soil temperature in °C and
electrical conductivity of the soil
in mS/cm are also read out. The
additional recording of battery
voltage enables empty batteries
to be recognised at an early stage
and so prevents data losses.

Measuring the volumetric water
content
The SMT-100 combines the advantages of the low cost FDR sensor systems with the accuracy of
a TDR system. Like a TDR, it measures the travel time of a signal
to determine the relative permittivity of the soil. And like a FDR, it
converts this relative permittivity
into an easy to measure frequency. But unlike an FDR it isn’t based
on a capacitor, but utilizes a ring
oscillator to transform the signal’s
travel time into the measure frequency. The resulting frequency
(>100 MHz) is high enough to operate well in clayey soils.
Compact, functional and robust:
the PCB board based design allows for an economic design, and
the blade shape facilitates installation. The casing and cable is
water sealed. Different communication protocols are available, as
well as analogue output. Output:

The SMT-100 has a broad measurement range. It is maintenance
free and frost resistant.
With short response times and
low disturbance by salinity it is
designed for a long term observation.

FDR - Frequency-Domain-Reflectometry
As for the TDR measurement, the water content is indirectly determined
via the relative permittivity εr in this method. Unlike the TDR method in
which the term of the reflected signal is measured, in the FDR method the
differences between the sent and reflected electromagnetic waves are determined and the water content of the soil calculated from this.
The resistance of the soil, in accordance with its relative permittivity, influences the reflection of the sent sinus waves causing a slightly altered wave
compared to the initial signal. The relative permittivity is then calculated
from the difference between the two waves at two points and then the
water content calculated.
Moisture Meter - HH2
The Moisture Meter is a versatile
device for Delta-T moisture sensors ThetaProbe, SM150T and
WET Sensor (no temperature display possible).
The HH2 offers high functionality in a compact handheld device
which has been specially developed for field use. The measured
values are listed directly on the
LCD and may be saved for later
use on the PC. The device can
be operated with one hand for
practical use in the field. For every measured value the measurement time and a unique sample
number, a measurement point
number and a sensor identification number are stored.
The data is transmitted to the PC
using the supplied RS-232 cable.
The HH2 software for Windows
PCs offers a Wizard for data inport.
The data can also be read out directly in Excel or other spreadsheet programs or in programs for
irrigation control. Alternatively,
the data can also be downloaded
as ASCII data.

EnviroSCAN
Sentek Plus „All-in-one“
Tubular probe
EnviroScan probes continuously
record the water content in the
soil profile. Depending on equipment with soil moisture or TriSCAN sensors, the salt and fertiliser content (quantity of dissolved
ions in the soil water) can be measured in addition to soil moisture. The soil moisture is measured
using FDR (Frequency Domain
Reflectometry).
Usually, 16 sensors may be placed
on a probe in flexible depth (at
intervals of 10 cm). This system is
suitable both for measurements
near the surface (starting from
10 cm) and for depth measurement (> 40 m).
The use of different interfaces
(e.g. RS232, RS485, SDI-12, Voltage, Modbus) means that the
probes can be connected not only
to Sentek systems such as Sentek
PLUS and Sentek SOLO but also
to a large number of other data
loggers.
The Sentek Plus system transmits
data from EnviroScan and EasyAG
tubular probes wirelessly using
mobile communications to an Internet server. The data are retrieved from the office and displayed
in the software IrriMAX.
The data can be read out using
GPRS via the Internet or in situ
using the connection cable.
The sensors are located in the
installation tube. This therefore
avoids direct contact with the soil
and means that the probes are
easier to maintain if required.
If installed correctly, the soil
structure is not disturbed so that
the actual water movement in
the surrounding soil can be recorded.

This way all components necessary for operation and data transfer are integrated into the housing
- a Modem, a lithium battery with
a minimum lifetime of 12 month
under normal use and an antenna. Furthermore the system features a bluetooth interface for
diagnosis and configuration.
There is no need for solar panels,
external Data loggers or modems
and hence there are no cables
that are prone to damages caused
by game animals or agricultural
machinery. Therefore the „All in

TRIME-PICO
TDR - Time Domain Reflectometry
Soil moisture measurements using the TDR principle are based on the fact
that the relative dielectric constant of water (ε0 = 81) is far greater than
the other elements of the soil (min particle: ε0 = 2-5 and air ε0 = 1) and the
moisture in the soil therefore decisively influences its dielectric constant.
The TDR probe initially only measures the dielectric constant of the considered soil body.
The soil moisture is then determined from this. The measurement of the
dielectric constant ε is based on a speed and runtime measurement of an
electromagnetic wave in the soil body. Parallel rods of the same length are
introduced to the soil through which highly frequent electromagnetic pulses are conducted. The dielectric constant is obtained from the term of the
pulse within the rods and the length of the wave guide.
Easy Test FOM/mts
FOM/mts is a portable batterydriven and microprocessor-controlled TDR meter designed for
the simultaneous in situ measurement of the volumetric water
content, of the electrical conductivity and of the temperature
in the soil. Using this instrument
both continuous and periodical
measurements can be made and
therefore also the distribution of
the soil moisture, conductivity
and temperature in different soil
horizons recorded. The instrument is equipped with a keypad
and a matrix graphics display for
menu navigation and measured
value display. As an option, the instrument can be equipped with a
GPS module to record the geogra-
phical coordinates of the measurement points. Using a USB interface, the measurement data can
be transferred to a PC.

TRIME-PICO32 - sensor with integrated TDR electronics
The intelligent TRIME rod probe PICO32 is ideally suited for in
situ monitoring systems to record
the moisture in soils and in other
porous materials. The integration
of probe and TDR analysis electronics in one sensor is unique.
Compared to other measurement
methods, an exact measurement
even at high temperatures and
conductivities is guaranteed with
the TRIME-PICO32. An integrated temperature sensor provides
additional valuable information.
With the small housing of 32 mm
in diameter, the TRIME-PICO32
can be installed without problem
in relatively homogeneous soils
and with its 11 cm rod length
provides best possible representativity. In view of its mechanical
toughness, the TRIME-PICO32
may be used in a mobile environment with the Bluetooth module
PICO-BT.
Advantages
•Small and tough design, ideal for
mobile use
Thanks to a protective housing in accordance with IP68, both sensors are
suitable for long term use.

Trime-T3
Tubular probe
Using the Trime-T3 tubular probe, it is possible to record moisture profiles up to a depth of 3
m in combination with the probe
head Trime-T3/IPH54 with integrated TDR electronics even up to
a depth of 50 m. Profile measurements are possible in increments
of 18 cm (T3) or 11 cm (T3C), whereby the measurement volume of
the T3C is smaller than that of the
T3. The Trime-T3 is therefore particularly suitable for heterogenous
soils whilst the T3C is designed for
homogenous and saline soils. The
moisture measurement is made
in accordance with the TDR principle. The measurements are conducted in plastic tubes from particularly tough and impact-resistant
TECANAT plastic. The tubes are
inserted into the soil before the
measurement and remain there
during the measurement series.
Probes with Trime-T3/IPH54 can
be inserted without plastic tubes directly into the borhole and
sealed completely with sealing
mass, thereby guaranteeing the
long term operation of the probe
for years even under harsh ambient conditions. The data may be
read out directly by the Trime-HD
or a data logger.

Soil Salinity Sensor
The salinity sensor that measures
subsurface pore water salinity
content in place.
If you need to monitor the progression of salt build up in soil
profiles, or need to see the effects of „leaching“ sequences, the
5000L Series can do that at specific
points in the profile. Only the
5000L sensors give discrete point
evaluations of in-situ total dissolved salt contents in the pore waters. Fabricated from proprietary
15 bar porous ceramics the pore
water is measured through the full
range of plant growth. The sensor
remains „saturated“ with ambient
pore waters from saturated 0 to
1500kPa matric suction. Constructed of durable acrylic housing and
made for years of subsurface use
the spring loaded head provides

Suction probe technology
The constituents and composition of soil water and soil air provide important information for the analysis of substance transportation and substance spread in soils and permit insights into internal processes through to
“... soil life (=Edaphone)...”.
Suction probes offer the possibility to obtain samples of the soil water or of
the soil air for subsequent analysis.
The suction probe itself is installed in the soil. The vacuum created by a
vacuum pump draws the water or the air into sampling vessels.

Suction probes with ceramic cup
With this suction probe the percolate is drawn from the soil to a ceramic cup (P80; 20 x 50 mm). The
acrylic glass standpipe (Ø 20 mm)
simultaneously serves as a collection compartment. No additional
sampling vessels are therefore necessary but may be connected as
required. The storage of the sample in the standpipe means that it
is extensively kept at soil temperature. Transport and vacuum line
are kept separately and can be individually sealed by drain taps at
the hose connections. The structure of this suction probe permits
a completely autonomous operation and prevents the percolate
being drawn back into the soil in
dry phases. Both the tubes themselves and the tube connections
are made of inert PE to prevent
falsification of the samples.
The suction probes with ceramic
cup are also offered as an underground version. Instead of the
standpipe, this design has a tube
to the soil surface which is connected to a separate sampling
vessel.
For the taking of larger samples
the ceramic cup with integrated
100 ml collection vessel is recommended.
Suction probes with plastic sintered cup
This suction probe can also be
equipped with a glass cup instead
of a ceramic cup for the detection of organic substances such as
pesticides or DOC without absorption losses.

The suction probes with cups
made of hydrophile, sintered PE
(ultra high molecular) and nylon
diaphragm (pore size 45 µm) have
been specially developed for the
detection of heavy metals in the
soil water. These are absorbed at
the ceramic surfaces leading to
a falsification of the heavy metal
concentration in the sample. PE
and nylon do not absorb heavy
metals so that the heavy metal
concentration in the soil is transferred into the sampling vessel
cleanly. The higher permeability
of the plastic sinter compared to
the ceramics also permits larger
sample quantities to be taken in a
shorter period.
The PE tube is then laid underground from the suction cup to
the site of sampling so as to guarantee the storage of the sample
at ambient conditions which are
as natural as possible.
The suction cups are covered with
wide mesh PE net in order to protect the nylon diaphragm from damage and for optimum connection
with the pore system of the soil
matrix. The acrylic glass standpipe
(Ø 25 mm) serves as collector. This
means that the suction probe can
be used completely autonomously and the soil solution is stored at
the natural ambient conditions.
A separate sampling vessel can
be connected without problem.
By separating the feed and vacuum line, the percolate cannot be
drawn back by the soil moisture
tension. The suction cups are also
available without standpipe for
underground installation.

Porous Ceramics
Suction plate nylon diaphragm
The ceramic products offered in
this section are the most popular
which have been sold for decades
to customers. The unique characteristics and quality of these porous ceramics allow them to be
used in a variety of applications.
The natural wetting abilities of
a porous ceramic, the uniform
pore sizing, and inert raw materials provide an excellent finished
product for research or industrial applications. Acombination of
these attractive features with the
strength and durability capabilities of a variety of ceramic shapes
leads to a limitless number of excellent possibilities.
Suction plates offer the advantage
over suction cups of obtaining the
soil solution over a larger area.
The area from which the percolate is obtained is defined exactly
and the sample does not originate
from only a single point measurement. The plates are installed
laterally from an excavation point
and therefore draw the soil solution from the undisturbed soil area
above.
The surface of the suction plate
consists of a nylon film with a pore
size of 0.45 µm. This is supported
by a layer of hydrophile PE sinter
beneath. The housing of the suction plate is made by standard of
inert PE but can also be supplied
in stainless steel.
Advantages
•Drawing of the soil solution over
a larger area
•Soil solution from undisturbed
soil
For lysimeters, lysimeter bases can, on request, be equipped with up to 7
suction plates depending on size.

Time controlled suction probe system SSA-121
This suction probe system is suitable for conveying air and gases as
well as for pumping liquids over
vacuum and is specially designed
for long-term constant pressure
conditions.
Unlike other suction probe systems or pumps, the SSA-121 has a
pressure reservoir with a volume
of 10 l or 20 l, depending on the
model. This ensures long-term
stable pressure conditions in the
system regardless of the ambient
conditions and minimizes pressure surges during pumping.
For the safe and practical use
under field conditions, the housing
is dust-and jet water-proof (IP 65)
and the device is equipped with
a 12 V DC power supply to be independent from mains current.
The stable pedestal ensures a safe
stand even during operation.
Tension controlled suction probe systems
The diaphragm gas pump with
Hostalen pump head and elastic
membrane is characterized by
a high pneumatic performance,
high gas tightness and low flow
losses. Due to the closed membrane surface and the special
sealing system as well as the new
valve system it has a long life time
(about 20,000 Operating hours)
and is almost maintenance free. If
necessary, diaphragms and valve
plates can easily replaced without
special tools.
The control of suction probes in
accordance with the tension in
the surrounding soil permits soil
solution to be drawn from various
soil moisture areas with adjusted
pressure. The respective vacuum
results from the prevailing tension amplified by a freely selectable amplification factor and / or a
freely selectable offset. Up to four

SOIL RESPIRATION
The exchange of soil air between the soil, vegetation, and the atmosphere
is an important subject in many ecological research questions. With respect to climate forecasts, greenhouse gases are important parameters for
models and assessments.
The gas exchange between the soil and the atmosphere results from numerous complex and non-linear relationships, such as physiological, biochemical, chemical, ecological and meteorological conditions.
It is possible to sample soil-borne gases by means of accumulation in closed
hoods, flows through open hoods or the use of special soil gas lances.
The analysis of soil gases is carried out using gas analyzers.

SOM - soil oxygen meter
Soil air sampler
The soil air sampler offers a simple to use and favourably priced
option to obtain soil air samples.
The sampler tube made of V2A
stainless steel may be easily inserted into the soil due to the diagonal tip.
A stainless steel filter prevents the
tube becoming blocked. The tube
connection with tap at the upper
end of the sampler is made of inert PE and facilitates simple sampling.
Advantages
•Favourably priced
•Fast and simple measurements
The soil oxygen meter (SOM) is
used to measure root respiration
and detects the oxygen content of
the soil in %. An auger drill is used
to prepare a hole in the soil into
which the sensor is placed.
The oxygen meters are generally
placed at vertical internals of 20
to 50 cm to establish a vertical
profile of the oxygen content of
the soil.

Substrate sampler
The substrate sampler has been
developed for in-depth field measurement of air permeability and
pore gas composition in the loose substrate in particular in loose
piles. With the assistance of this
measurement instrument, statements on the air- filled pore volume and its content of oxygen,
carbon dioxide and methane may
be made at increments of 0.1 m
in a depth of 4 m. As a result of
the combined measurement of air
permeability and soil gas composition, up to 5 minutes per individual measurement is saved compared to sole gas measurement.
The sampler consists of four connectable 1 m pipe pieces so as to
obtain a sampler length which is
always adapted to the local conditions.
The sampler may be inserted manually and also by hammer. The
air contact surface to the substrate is around 200 cm² and is sealed
by a cone over the measurement
area against the permeation of
outside air.
The vacuum to obtain the pore
gas is generated by vessels filled
with water whose average height
difference is set to 0.3 m. The vacuum generating unit is secured
on a 4-foot stand which can be
equipped optionally with ground
pins to increase stability on a loose base. The gas composition is
determined directly in situ using a
connected digital gas meter.
Advantages
•Time saving of up to 5 minutes
per measurement compared to
traditional individual measurements
•Sampling from defined air compartment due to self sealing of
the sampler tip
•Optional practical and safe transportation in aluminium case

Picarro G2201-i CRDS Analyzer
δ13C for methane (CH4) and carbon dioxide (CO2)
Isotope analyzer for determining
sources of carbon dioxide. Soils
as sources and sinks in the carbon
dioxide and methane cycle represent an important variable when
examining the global climate balance. The various components of
the soil/atmosphere system contribute to the situation in a complex manner. Isotope studies are
an indispensable tool for an accurate knowledge of the conversion
processes.
The examination is made considerably simpler by the G2201-i.
It is ready to use in minutes, and
is small and robust for simple use
in the field. The device can be
operated for months without interaction on the part of the user.
The concentrations of CO2, H2O
and CH4 are recorded accurately, thereby compensating for the
mutual interactions of the various
species. There is consequently no
need for gas drying.
Various systems are available for
collecting samples, enabling diverse measurements:
• Dissolved inorganic carbon (DIC)
• Dissolved organic carbon (DOC)
• Carbonates
• Solids
• Small volumes of gas
• Highly concentrated gas samp-
les
• Closed chambers
For measuring gas flows in the
field
Gas flows can be recorded in various ways. Gas measurement
hoods which either create a controlled gradient (open systems)
or which interrupt the exchange
for a set time (dynamic, closed
systems) or prevent it completely
(fixed, closed systems) have become established as the reference
method.
Open systems permit the exchange across the top edge and
provide a measurement path beneath it that can be used to determine flow rates according to the
gradient. The top opening ensures that the plants are affected
as little as possible, and that the
temperature and gas composition do not differ significantly from
that of the environment.

Penetrometer
The penetrometer measurement is a simple and yet very sensitive method
of determining the penetration resistance in the soil. This value is of great
importance both for agriculture and for the assessment of building ground.
The soil compaction, for example in the driving tracks of agricultural equipment, but also the success of processing technologies can be assessed. For
construction projects the penetration resistance is a sign of stability and
the load bearing capacity of the soil.
Type of soil, density, soil moisture, humus content and coarse soil content
are factors influencing the penetration resistance. In view of this bandwidth
of influencing parameters and the simple handling, penetrometers are very
well suited to make statements about the homogeneity of soil areas.

Mobile field penetrometer
This electronic penetrometer was
specially developed on behalf of
the Humboldt University in Berlin
to determine penetration resistance with high spatial resolution
for large test areas in a short time
and with minimum physical effort.
The penetrometer structure, in
terms of the electronic penetrometer with rods and pressure
sensor, is mounted on a sampling
vehicle. The conducting of the penetrometer measurement is automatically controlled by a track
system. To prevent springing movements by the shock absorbers,
the vehicle is lifted out with hydraulics and two supports for the
duration of the measurement.
The corresponding software runs
on a connected laptop; in addition to controlling the test, it is also
used to record data, for data processing and to display graphics.
The visualisation can be used on
site as basis for further measurements.
Installation on a sampling vehicle
makes it possible to change locations quickly. The penetrometer
is activated at the desired measurement station by the controller
and automatically inserted in the
ground.
Manual penetrometer
The resistance created is registered by a pressure sensor and saved on the connected laptop. The
automated penetration using the
track system ensures the same
penetration conditions at all
times. The penetration resistance
is dependent on the penetration speed. This remains constant
throughout the entire test run
when using the mobile field penetrometer. The crucial penetration angle of 90° for measurement
is also always maintained consistently by this system. Compared to manual measurement, this
produces greater accuracy and
improved repeatability of measurements.
What is more, the physical force
and size of the person conducting
the test are no longer decisive for
the quality of data obtained or the
measuring conditions required.
The stability of the penetrometer rod alone limits the application range of the penetrometer.
Dry and hard soils where physical
force alone is insufficient to insert
the penetrometer in the soil can
thus also be sampled. To protect
the measuring device from damage, e.g. from stones or hard layers
of soil, a maximum pressure can
be set as stop criterion during
The penetrometer basically consists of a measuring instrument, a
probe rod and a probe cone. The
instrument is pressed at a right
angle into the soil by exercising
pressure on both handles. Uneven
pressing does not produce representative measured values which
are exaggerated for specific soils.
The resistance measured by the
probe cone can be read off on
the black pointer of the manometer. The maximum resistance
recorded during the measurement is shown by the red pointer.
General principle: the larger the
probe cone, the more precisely
the penetration resistance may be
determined.
Uses
In view of its depth of use, the instrument may be used for the following tasks:
•general soil investigation
•simple foundation appraisal
•examination of the artificial compaction of the soil
•examination of the growth conditions for plants to be expected
•determination of compacted horizons
sampling. The probe rods and probe cones can be replaced easily if
measurement conditions change
or the control template indicates
excessive cone wear for the cone
test.
Uses
Advantages
The mobile field penetrometer can be used in the agricultural and civil
engineering area:
•High repeatability
•High mobility
•Minimised expenditure of time
•General soil examinations
•Examination into the suitability of the soil for agricultural and civil enginee-
The penetration resistance of the
soil (kPa/cm2) can be determined
by dividing the displayed value
by the surface area of the probe
cone. The value to be expected
for the penetration resistance determines the surface of the probe
cone to be used. For higher values, a smaller cone is used.
Penetrometers are used to determine the penetration resistance
(load bearing capacity) of the soil.

Measurement instruments for
hydraulic and pneumatic conductivity
The saturated hydraulic conductivity kf specifies the water volume which
flows through a specific area with a specific gradient per time unit. The
pneumatic conductivity is the equivalent value for gases. Both are physical
parameters of the soil which provide information in particular on structure, pore continuity and tortuosity of a soil. In addition to the potential
gradient, the kf value is the decisive parameter in the determination of
flow density in saturated porous media (DARCY Law). Usually, the saturated
hydraulic conductivity is not determined directly but rather values from
which the saturated conductivity may be calculated, such as the infiltration
speed or the water content in known soil moisture tension gradients.

Hood infiltrometer / IL-2700
The hood infiltrometer is used to
measure the hydraulic conductivity of soils in virtually saturated
areas as field tests. The infiltration is made from a sealed hood
placed on the soil and filled with
water. The circular soil surface
covered by water beneath the
hood forms the source area for
the infiltration flux. No additional
contact layer and no preparation
of the soil surface is necessary on
the measurement area. This not
only saves working time but also
makes it possible to measure the
infiltration and conductivity under
completely natural conditions in a
destruction-free manner.
The pressure beneath the hood is
controlled using a Marriott’s water supply. The effective increase
in pressure on the soil surface can
be freely selected between zero
and a vacuum up to the bubble
point of the soil. This pressure level is shown exactly on a U-tube
manometer.
The hydraulic conductivity is calculated from the stationary flux
rates determined in the test run
according to WOODING (1968).
With the IL-2700 the measurement data for the flux rate is
electronically recorded with a
pressure sensor combined with
a handheld instrument IL-2700.
With the corresponding software
they are transferred to the PC and
analysed.
GUELPH PERMEAMETER KIT
The hood infiltrometer is also
available without electronic data
recording as a favourably priced
alternative which is tough enough
to withstand adverse measurement conditions.
In order to guarantee an optimum
adjustment of the experiment to
the prevailing infiltration conditions, two hoods are available
with a ratio to infiltration areas
of around 1:2. The tension chamber, which is an available option,
creates a tension infiltrometer
together with the Mariott’s water
supply which permits infiltration
experiments up to a water tension of around 60 hPa irrespective
of the bubble point of the soil.
For maximum protection and
simple handling during transportation and storage, the complete
system is packed in an aluminium
framed case with carry grip and
foam inlays.

Double ring infiltrometer
ku-pF apparatus
The measurement of water infiltration in the soil is an important indicator
of the efficiency of irrigation and drainage, optimisation of water availability for plants, improvement in the harvest yield and erosion reduction.
The double ring infiltrometer is a
simple instrument used to determine the infiltration rate of water
into the soil. The infiltration rate
is determined as the quantity of
water which penetrates the soil
per surface area and time unit.
This rate can be calculated using
the measurement results and the
law of DARCY. The standard set
of the double ring infiltrometer
consists of a few sets of stainless
steel rings with different diameters (for transport reasons).
Several measurements may be
conducted simultaneously which
leads to an extremely reliable
and precise average result. If vertically infiltrated water flows off
naturally, the outer ring serves as
separation protection. The measurements take place exclusively
in the inside ring through which
the water flows virtually vertically.
In order to achieve good measurement results, it is important to
consider the different factors influencing the measurements: the
surface vegetation, the degree of
soil compactness, the soil moisture content and the soil properties
such as horizontalisation (strata).
The best results are achieved with
the “field capacity” of the soil. The
ring infiltrometer may be used for
the following purposes amongst
others: irrigation and drainage
projects, run-off investigations,
determination of the intensity of
precipitation and of the effects of
soil working measures.

The ku-pF MP10 is a laboratory instrument for the automatic
determination of any saturated
hydraulic conductivity ku and the
pf curve (water tension curve) in
accordance with the condensation method on up to 10 soil ring
samples simultaneously.
The apparatus is designed for the
use of the UGT soil sample rings
with 250 cm³ inner volume and
41 cm² cross sectional area. These
soil sample rings have bore holes
arranged exactly at height intervals of 3 cm for the insertion of
the tensiometers. However, they
may also be used for obtaining
samples separately from the ku-pf
apparatus.
The filled soil sample rings are set
onto filter plates, saturated and
sealed basally in the carrier basket
for the test run. The gradient resulting from the condensation on
the free ground surface is recorded by two tensiometers which
record the corresponding water
content and the flow rate by periodical weighing respectively.
Air bubbles are easy to recognise
and eliminate through the acrylic
head with bleed screw.
The arrangement of the samples
on the star shaped carrier which
rotates at the set test interval permits the examination of 10 samples simultaneously. The sample
on the weighing position is lifted
from the carrier by lifting the scales so that it is standing free. The
weighing data and the tensions
here are stored on the internal
data logger. Automatic measuring
produces continuous measurement series with a minimum of
monitoring. The scales are automatically balanced between weighings. Drift effects or any foreign
bodies on the scales do not therefore cause any interference.
The ku-pf apparatus works independently of a PC due to the integrated data logger and a microcomputer. A connection must be
created to the PC only for maintenance, test start and reading out
of the data.

Low Tension System
Hood permeameter by HARTGE
Natural water movement occurs
predominantly with very small
pressure gradients.
Currently, the water movement is
described almost exclusively as a
laminar flow with DARCY equation
whereby the flux speed is proportionate to the effective pressure
gradients. The usual kf measurements in soil science are conducted with comparatively high gradients which are rarely to be found
in the natural water movement in
soils. HARTGE therefore advocated the measurement with very
small gradients. The Hood permeameter by HARTGE meets these
requirements. It serves to determine the kf value of the soil ring
samples in the laboratory from
the flux rate and the corresponding pressure difference whilst
keeping the pressure gradients as
small as possible.
The saturated sample in the manual soil sample ring is placed
in a tub on a filter plate and covered completely with water. A
dome filled with water is placed
over the soil sample ring beneath
which a pressure gradient is generated over the sample height. This
dome is suitable for the manual
soil sample rings offered by UGT
so that the soil sample can be inserted directly.
In the test run, the water volume
flowing through the sample during a specific measurement time
is determined for the stationary
flow. The area and length of the
flow path are determined by the
geometry of the soil sample ring.
Depending on version, the pressure gradient is shown as height
difference in the standpipes or recorded by a pressure sensor.

Chameleon Kit
The Chameleon Laboratory, an
accurate, versatile, and fully automated laboratory system for
measuring saturated hydraulic
conductivity (Ksat). Chameleon is
capable of performing Ksat measurements according to both the
Falling-Head Method and Constant-Head Method. Thanks to
the Monitor® Precesion Pressure
Transducer, and the Chameleon
Software Application, both measurement methods are fully automated. The Chameleon Permeability Laboratory System allows
for automated Ksat calculation in
just a few minutes to a couple of
hours. The user simply needs to
collect samples and connect them
into the system. The software will
record the data, notify the user of
steady state, calculate Ksat, and
provide reports including charts
and graphs. With both constant
head and falling head calculation
capabilities, this is the most complete permeability system.
Aardvark Permeameter
The Chameleon Permeability Laboratory System is the ideal configuration for calculating Ksat
quickly and effectively. Soil cores
are directly inserted into the system assuring minimal disturbance
for maximum accuracy. The automated software, compatible exclusively with Soilmoisture‘s new
Monitor Transducer, allows the
user to get results limited labor
and error. Constant head and falling head methodology makes this
a diverse educational tool and the
perfect system for a wide range of
research. Furthermore, the components used in Chameleon can
be reconfigured to create other
types of laboratory systems, such
as Soilmoisture‘s Tempe Cell system, with little or no additional
parts. The system includes the
complete Monitor Precision Pressure Transducer software package
so that the transducers can also
be used for other applications.
Knowing soil hydraulic characteristics is essential for many
agronomic applications such as
irrigation scheduling and application rates, watershed and runoff
predictions, and drainage system
capacities.
The Aardvark Permeameter is the
very first battery-operated automated Constant Head Borehole
Permeameter. The Aardvark sets

Set for the pF determination with ceramic plates
The equipment is suitable for the
determination of pF curves in the
range of pF 2.0-4.2 (0.1-15 bars of
soil moisture tension). Furthermore, the sets are suitable for the
calibration of soil moisture blocks
or other soil moisture measurement equipment. The standard
set contains inter alia: two extractors with ceramic plates (0.1 MPa,
0.3 MPa and 1.5 MPa and 1. 3 and
15 bars) and accessories, soil sample rings, a pressure control panel
and a compressor.
Several ceramic plates with soil
samples can be placed in the extractor at the same time. The
pressure control panel is standard
equipped with two manometers 0-2 MPa and 0-0.4 MPa (and
0-20 bars and 0-4 bars). The supplied compressor (220V / 50 Hz)
is specifically designed for this
purpose: maximum pressure 2.0
MPa (20 bars), built in safety precautions, completely guarded and
quiet.
Principle
Moisture is removed from the soil
samples by raising the air pressure in an extractor. A porous ceramic plate serves as a hydraulic
link for water to move from the
soil to the exterior of the extractor. The high pressure air will not
flow through the pores in the plate because these are filled with
water. The smaller the pore size,
the higher the pressure can be before air will pass through. During
the test run at any set pressure
in the extractor, soil moisture will
flow around each of the soil par-
ticles and out through the ceramic
plate and outflow tube. Equilibrium is reached when water flow
from the outflow tube ceases. At
equilibrium, there is an exact relationship between the air pressure in the extractor and the water
tension in the samples (and hence
the moisture content). Accuracy
of equilibrium values will not be
above that of the regulation of
air supply. Therefore, the pressure control panel has independent
double regulators.
Use
If the properties of the moist soil sample are known, the following values may
be determined:
•The pore volume of the soil.
Pressure Membrane Extractor
Pressure Membrane Extractor (0 - 15bar) Model 1000 for water retention
curves from shrink / swell soils to 15 Bars
Advantages
Compared to other methods, such
as compaction, centrifugation, molecular absorption etc, the advantages are as follows:
•Relatively simple method
•Reliable way of removing soil
moisture from soil samples
under controlled conditions
without disturbing the soil
structure.
•The method may be used on
prepared samples or undisturbed samples. The soil structure
is not disturbed. The characteristic pF curves may be developed
for each soil type. These curves
relate the moisture tension at
which the moisture is held in soil
to its moisture content. Studies
of soil moisture movement and
of quantity and availability of
soil moisture have shown this
relationship to be important for
plant growth.
A common problem in soils research is determining water retention curves for various soil
types. This applies to non soil
experiments where the material under study „curls“ as it dries.
The model 1000 is a pressure /
membrane type extractor. It is
designed to contain shrink-swell
soils during extraction. A special
EDPM rubber “hold down“ diaphragm is inflated, with 1.81kg of
force holding the soil in hydraulic
contact with the cellulose membrane surface. The cellulose membrane material is a pure cellulose
and has a pore size of 2.4 nanometers. The cellulose membrane
can withstand over 10,000 kPa
bubbling pressure. The standard
model 1000 (100261) can test up
to 12, 5.5 x 1 cm high samples and
operates in the 0 to 1500 kPa (0 to
15 bar) soil suction range. Choose
an optional PM cylinder height, to
handle undisturbed cores up to 3
inch high.
The Pressure Membrane Extractor includes the following components:
Top and bottom plates, 5/8“ (1.6
cm) high by 11“ (28 cm) inside
diameter cylinder and clamping bolts, cylinder seal O-rings,
screen drain plate, compressing
diaphragm, and eccentric clamping screw assembly. Connecting
hoses (2 required), cut celullose
membrane discs, PM Hinge, and
torque wrench with socket are
ordered separately. Soil sample
retaining rings and cylinders of
various heights are available separately.

PL-300
Air pycnometer
he PL-300 is a field measurement
instrument to determine the
pneumatic conductivity of soils.
This value describes the waterfree pore space of the soil and is a
function of water content.
A defined air flow is generated
using a measurement chamber in
the soil volume investigated. The
rate of flow is determined from
the drop in pressure through a calibrated two stage measurement
throttle in the PL instrument. The
pressure difference above the soil
volume is recorded by a further
pressure sensor and supplies the
pressure gradient of this flow.
The pneumatic conductivity is
calculated from these test parameters using the DARCY equation
and shown in the instrument display.
PL measurement chamber
PL surface chamber
The PL-300 also has connections
for an electronic soil tensiometer and a moisture probe so that
soil moisture tension and/or soil
moisture may be recorded parallel to each other. For this purpose
UGT provides a specially adjusted Tensio 150 tensiometer and
a TDR moisture probe each with
the suitable plug. The data of all
connected sensors as well as the
calibration data of the measurement chambers and a marking of
the measurement point are saved
and managed by a microcomputer within the instrument.
Its compact and tough design
make the PL-300 a practical and
portable field measurement instrument.
In accordance with the requirements of the location, different
measurement chambers are
available:
•PL-300 measurement chamber
for homogenous flow according
to DARCY with integrated pressure probe
The air pycnometer is an innovative measurement instrument to
determine the pore volume of a
substrate sample in the laboratory. It is suitable both for undisturbed soil samples as well as for
bulk goods such as sands, gravels
or plant granulate. The measurement chamber is permanently
connected to the basic body and
is sealed by a lid which is held in
place by a bar. A soil sample ring
is not essential to conduct the
measurement. Due to the large
measurement chamber with a volume of 2120 cm³, appropriately
large samples may also be examined which increases the accuracy
of the measurement and makes
a few of the investigations at all
possible.
The design of this instrument is
based on the guidelines of the
FLL (Forschungsgesellschaft Landschaftsentwicklung und Landschaftsbau).
The measurement principle is
based on the isothermal gas expansion experiment according to
BOYLE-MARIOTTE. An additional
volume of a known size is filled
with compressed air, connected
to the measurement chamber of
known size with substrates sample and a pressure equilibrium
achieved. The compensating pressure is a measurement of the air
filled pore volume because only
the solids volume within the measurement chamber serves to push
out gas.

The pressure values are displayed by a digital manometer in
a freely selectable pressure unit.
The integrated compressor renders additional devices or gas
flasks superfluous as long as air is
used as measurement gas. As an
option, a different measurement
gas may be used via a separate
feed line.

Particle size distribution is an important property-determining feature of
soils. It is used not only to determine the type of soil but also provides important information on the quality of the soil, its water balance properties,
workability and suitability as agricultural or construction land. The distribution of fertilisers or pollutants in the soil also depends on the particle
size distribution. In view of this broad influential range, the knowledge of
the particle size distribution provides the foundation for many questions

12 samples with 4 fractions (optionally 2 fractions according to the US nomenclature) Patent-No.: DE 10 2012 207 898
Advantages
The Sedimat 4-12 works on the
basis of the KÖHN analysis to DIN
ISO 11277, which is so far the only
rational measurement method to
provide identical results for the
sedimentation analysis with same
dependence on the particle shape. In this method the sedimentation rate of the soil particles
at 25 °C is examined using a soil
sample which has been previously
homogenised and separated from
carbonates and organic substance
so as to create the particle total
curve, for example, which provides the foundation for many soil
examinations.
•Reduction in workload
•Complete analysis for 12 samp-
les in 4 fractions per day possible
•Exact realisation of the prescribed measurement conditions
•High repeat accuracy
Automisation:
The sample preparation (sieving,
weighing, destruction of carbonate and organic substance) and an
initial homogenisation by shaking
or upturning is done by hand before installation of the soil samples in the Sedimat.
The fine soil is composed of the
fraction’s coarse silt (gU), medium silt (mU), fine silt (fU) and
clay (T). The diagram below shows
this composition. As a result of
the different particle sizes (< 2.0
µm - < 63 µm) and shapes, the
individual fractions have different
sedimentation rates. A controlled
sedimentation of the homogenised soil suspension can be used
for separation due to the different
sedimentation properties and
therefore to quantify the individual parts.

The separation of the fractions
is made using a pipette analysis.
During the sedimentation process, defined volumes are taken
in a defined height from the suspension at defined times and their
solid content then determined.
The manual conducting of the
test contains many sources of error due to the high requirements
placed on accuracy, such as devi-

ations in the depth of submersion
of the pipette or the time of taking the sample and is very laborious due to the long sedimentation
rate of fine soil particles.
The work is considerably reduced
and accuracy improved by automating this measurement method. Subjective measurement
errors are ruled out. Temperature
fluctuations, vibrations and turbulance which have a great influence
on the measurement accuracy are
minimised. Since the work is restricted to preparing samples and
their analysis, a complete KÖHN
analysis on 12 samples for all four
fractions can be made using the
Sedimat 4-12. Exactly observing
the test parameters during homogenisation, temperature control
and pipetting leads to a statistically reliable result. The measure
of variation on repeating the test
with the same samples is < 1 %
(with respect to the weighed samples) using the Sedimat.
*Submersion depth at sedimentation time at 25 °C to DIN ISO 11277:
•Fraction 1 (gU): •Fraction 2 (mU): •Fraction 3 (fU): •Fraction 4 (T): 20 cm ... 49 s
10 cm ... 4 min, 7 s
10 cm ... 45 min, 52 s
10 cm ... 6 h, 52 min, 50 s
Temperature control:
Homogenisation:
During the entire test run, the
samples are placed in a temperature controlled water bath to
guarantee constancy of temperature. After adjusting the samples and starting the program, this
water bath is heated to 25 °C. The
samples must then remain in the
water bath for at least 30 minutes
before the test can start. The exact observance of temperature is
important and also prescribed according to KÖHN because this has
a very great influence on the sedimentation rate of the particles.
The soil samples are stirred using
a propeller agitator with variable
speed and submersion depth. The
specially developed stirring routines guarantee complete homogenisation of the sample. In order to
prevent falsification between the
samples, the agitator is cleaned in
a bath before changing the sample and dried at very high speeds.
After stopping the agitator the
time window for the sedimentation time to DIN ISO 11277 is open
(see Tab. 1).
The suspension is taken using a
piston operated pipette with lateral suction opening. The prescribed submersion depth of the
pipette is controlled using an optical surface sensor so that this is
always exactly identical irrespective of the level of fill of the sample
vessel. For the fraction 1 ( gU) the
sample is taken at 20 cm depth,
for fractions 2-4 (mU, fU, T) at a
depth of 10 cm below the water
level. The suspension is taken out
3 s after reaching the prescribed
submersion depth. The pipetted
quantity of the suspension of 10
ml is defined by the piston operation.
After withdrawal, pipette and sensor are transported to a cleaning
station whereby any drops of
suspension are removed with a
sponge.
The pipette content is then emptied into a weighing jar at a defined position in the sample magazine. The inside and outside of
the pipette are rinsed with water
separately whereby the inner rinsing solution is similarly passed to
the weighing jar so as to capture
any fine soil particles.

FOGII Plus Digital Soil Calcimeter™ with UMP-1
The FOGII Calcimeter provides the
measurement of carbonate content. It has a rugged design and is
easy to use so that it is suitable for
field campaigns.
Based on the Scheibler method it
measures the temperature compensated pressure rise after application of hydrochloric acid. As
such it replaces the lab Scheibler
apparatus, and gives access to the
on-site determination of the carbonate content. The Plus version
comes with an integrated UMP-1,
which allows the in-field measurement of the water content and
the dry soil correction of the readings. This eliminates the obligatory drying step.
The calcimeter by Eijkelkamp is
suitable for the simultaneous determination of the carbonate content in 5 samples. Where possible
the vulnerable glass was replaced
by synthetic materials. Because
hydrochloric acid is used a stable
and ergonomic design was chosen. The calcimeter is delivered
complete with reaction vessels
and test tubes (without reagents).

As a consequence of the repeatability and the accuracy, a series of
measurements should be executed in a room in which there are no
differences in temperature exceeding 4°C. In addition the reagents
used must meet the standards for
analysis. It should also be considered that other gasses (for instance
in polluted soils) may be released.
The gas will then have to be purified first and the CO2 will have to

In these times in which buzzwords such as soil overuse and sealing, extreme flow-off and desertification are no longer simply issues for science, soil
erosion is assuming an ever greater importance.
Water and wind erode the soil and move it to other places. The incorrect
management of the soil, such as over-grazing, leads to the protective layer being destroyed and intensifies the natural erosion process to create a
man-made problem. This is because the excessive overuse of the soil leads
to an impairment in its productivity and even to its complete destruction.

Run off measurement instrument
Wind erosion sediment trap
The measurement system serves
to record and examine surface run
off and the erosion materials contained therein. The surface run
off water is collected in a collection channel and quantified by a
tipping counter before being filled
into sample vessels. The start and
intensity of the run off event is registered by an internal data logger.
The final filling of the samples of
the surface run off into up to 24
brown glass flasks is performed
fully automatically and solely via
water pumps. There are no bottlenecks which could clog, cause
a congestion or lead to the reduction of the flow speed. The
erosion material can thus be
transported in the flowing water
without impediment. Coarse dirt
is already retained by a stainless
steel sieve. In order to be able to
ideally record the different run off
events, the sampling frequency is
adjusted by a microcomputer to
the run off intensity.
The wind erosion sediment trap
automatically records the aeolically transported sediment material. This is weighed directly in the
system and then remains in the
weighing dish for the subsequent
investigations. The body of the
system is made completely of rust
free stainless steel and consists of
a base, logger, accumulator and
scales as well as rotatable head
section with wind vane for the
actual sample. The base of the
system is usually installed underground in order to guarantee that
the wind flow is influenced as little as possible and the apparatus is
steady.
With upstream connected run off
dividers, both test parcels and
also small capture areas up to 3 ha
in size can be investigated.
Combined with meteorological
and hydrological measurement
points a comprehensive picture of
the run off and erosion processes
can be obtained in this way.
With low run off quantities the
entire surface run off recorded by
the collection channel is taken as
sample in order to obtain a sample quantity which is as large as
possible. By contrast with a considerable run off event, sample
water is only taken at adjusted
time intervals. The remaining water is discharged after having been
quantified. This prevents the sample flasks filling too quickly and
guarantees that the samples are
distributed via the entire run off
event.
Advantages
•Fully automatic sampling
•Sampling adjusted to the run off
intensity
•Water distribution solely via
water points
Technical data
•Number of samples: 24
•Sample volume:
1000 ml
•Energy supply:Replaceable storage battery 12 112
The entire system is made of rust
free stainless steel which is inert
to the samples. It is installed underground so as to generate the
flow solely as the result of the
height difference and not to be
dependent on pumps and therefore to generate a free flow and
minimise energy consumption.
V/10 Ah
Also solar panels on request
Umwelt-Geräte-Technik GmbH
The wind vane means that the
head section with the inlet opening is always facing the wind
direction so that the wind flows
directly into the measurement
system. It hits a baffle plate from
which the sediment particles carried in the air fall onto the scales. The air flows out through the
outlet opening located above the
baffle plate. The scales weigh the
cumulative sediment and this result is recorded in the internal
data logger. The recorded data
therefore shows both the start
and intensity of an event.
Combined with a weather station, the aeolic sediment material
in connection with the meteorological parameters, particularly
the wind conditions, may be obtained. This provides a comprehensive picture of the wind related erosion. Using measurement
points such as this, the weighing
www.ugt-online.de
data may be recorded via the data
logger of the weather station so
that two loggers are not required.
The energy supply is then assumed by the weather station.
Usually both the wind erosion
sediment trap and the weather
station are supplied with power
by a replacement storage battery.
However, the power supply may
also be provided by solar panels
for autonomous operation.

Flow measurement
Reliably determining the quantities of inflowing and discharged water
forms the basis of every water management consideration, as well as the
consideration of many flow processes. This ranges from small lysimeters
to landfill sites, sealed surfaces and through to entire river basins. Various
measurement methods have emerged to adapt to different flow rates and

Polycarbonate tipping counters
These polycarbonate tipping
counters with a tipping tray volume of 0.1 l are particularly suitable for determining small flow rates
and can be used up to a maximum
discharge of 5 l/min. They offer an
inexpensive alternative to the V2A
tipping counters but are equally
weather-resistant. In addition, unlike V2A tipping counters, they are
food safe, and can therefore also
be deployed in drinking water.
H-flumes
A 1% sample of the volume can
be filled into the 250 ml PE collecting flask per tipping. The number of tipping actions is recorded
by a REED sensor which can be
connected to a data logger. In
the case of individual devices a
1-channel data logger (e.g. Easylog) is advisable. On request the
polycarbonate tipping counters
can be supplied with wall bracket
or base support.

material means that significantly
larger models are possible than
with plastic tipping counters. In
order to cater for all flow rates,
these tipping counters are availa-
ble with a large selection of tipping tray sizes ranging from 0.1 l
to 20 l. Up to a tipping tray volume
of 3 l the tipping counters can also
be equipped with a connection to
the sampling device.

H-type flumes were developed to
determine widely fluctuating flow
rates, from very low to extremely high volumes. For example it
is possible to measure seasonally
changing discharges or discharges resulting from heavy rainfall
events. Furthermore H-flumes
are also deployed to record agricultural and industrial discharge
processes. On condition that there is an open flume with free discharge on the outlet, they deliver
outstanding accuracy even in the
case of contaminated water. An
upstream stilling channel ensures
even distribution of the flow over
the entire measurement range.
The H-flumes are manufactured
from strong, stainless V2A steel.
The water level is gauged in a contactless procedure using ultrasonic transducers or capacitive sensors installed in a V2A protective
housing. In combination with UGT
data loggers, the temperature and
wind compensation of ultrasonic transducers takes place in the
data logger.

RBC flumes
Flow rate measurement system with data logger
RBC flumes are used to measure
quantities of water. Compared to
familiar flumes such as the WSC
or Parshall flumes, RBC flumes
give the most accurate results.
The RPC flume has been especially
designed for use in small streams
(irrigation, inflows and discharges,
furrows etc.). It is a simple and reliable instrument for measuring
water volume that flows onto a
field as irrigation. The standard
range includes flumes with different measurement ranges of between 0.1–8.7 l/s and 2.0–145 l/s.
Larger measurement ranges can
also be covered on request. The
essential condition for obtaining
precise measurement results is
that the flume be erected absolutely horizontally and that water
can flow onto the flume and out
of the flume without obstruction.
The value of the increased water
level can be read off on the measurement equipment (measuring
cylinder) at the end of the measurement flume. The flow rate
(discharge rate) is calculated using
standard formulae.
122
A compact, easy to handle device
to determine the flow rate in hoses, such as for pump trials in the
groundwater.
The impeller wheel flow meter for
2 to 48 l/min is combined with a
1-channel data logger to record
the flow rate at selected measurement intervals. The recording of
data begins automatically as soon
as a flow is registered. The value
of the preceding measurement
interval can be seen in the data
logger display.
The miniature data logger is supplied with Windows software for
configuration and data retrieval,
as well as a 1 m connection cable
for the PC. Measurement system
and hoses are connected using
quick couplings.
A pressure sensor can also be installed and connected to a data
logger instead of reading measurements off the measuring cylinders.
As a result the measurement
equipment is easy to install and
can be used without difficulty on
various hoses. Due to its small size
it can be easily transported and
with protection type IP 65 it is suitable for outdoor use.
Flow meter
This enables automatic measurement (and activation), storing and
reading. In the case of an automated flume, the threshold value of
the water level is recorded using
an extremely accurate pressure
sensor connected to a data logger.

The precise recording of series of water levels that are as complete as possible forms the basis for the hydrological description of the situation surrounding a body of water, the processes occurring within it as well as the
conduct to be expected and therefore also the water balance. In addition
to the purely hydrological significance, this information also has practical
use, for example for flood water warning, for the planning and management of water management and hydraulic installations and for shipping.

Level measurement equipment with ultrasonic scanning
The water level is measured from
the distance of the water surface
to the top of the attached ultrasonic sensor. The level measurement equipment is installed in a
soundproofed stilling pipe. Disturbances, particularly from waves,
are minimised in this way. The
measurement range is between
100 mm and 600 mm.
Level measurement equipment with capacitive level transmitter
In the case of this level measurement equipment, the water level
is determined via the change of
capacity between an internal and
external conductor. The capacitive level transmitter is installed in
a PVC protective stilling pipe as
protection from external influences, and in particular from waves.
The data are exported via a voltage output with 0 to 1 V.
In combination with a UGT data
logger it is possible for data recording and power management
to be controlled by micro computer. On site calibration means
that measurement values can be
directly read out as actual water
level. The data are exported via
an RS-232 interface on the data
logger.

Level measurement equipment with pressure transducer
Via the pressure sensor, the measurement system determines the
water level from the pressure of
the water column. This sensor
with gold-coated ceramic membrane and stainless steel housing is
compact, robust and durable. It is
placed in a PVC stilling pipe below
the lowest anticipated water
level. When combined with a UGT
data logger, the sensor can be calibrated to the installation depth
and directly read out the water level from the water column resting
on it.
When combined with a UGT data
logger with micro computer, the
data can be recorded and after
appropriate calibration the water
level can be directly read out and
an intelligent power management
can be implemented. The reading
out of the data from the logger
takes place using an RS-232 interface.

Umwelt-Geräte-Technik GmbH
The lake probe is a measurement
device designed to determine the
low pressure gradients associated
with the typical flow processes
at the bottom of lakes and rivers.
For example it is possible to establish whether water flows off via
the bottom of the lake or river,
or whether the groundwater additionally feeds the lake or river.
This information is important for
hydrological, hydrogeological and
geotechnical monitoring amongst
other things. The measurement
principle is based on the selective
determination of pressure gradients between the pore water in
the lake sediment and the absolute pressure from the free water
level in a closed, water-filled system. In addition to the composition of the upper sedimentary
layer (grain size, capillarity) and
the consequent penetration resistance of the probe, the measurement process is above all influenced by hydraulically dynamic
interactions between the current
near the bottom of the water and
the pore area current. The measurement equipment can be used
up to a water depth of 40 m and
www.ugt-online.de
operates at a fixed data recording
rate of 20 s. The pore water pressure is determined using a differential pressure sensor, while the
current water depth is calculated
at the same time using an absolute pressure sensor. The measurement position of the probe at
the bottom of the water can be
checked using the integrated incline sensor. Values are recorded
and administered in a micro logger in a handheld format. The UGT
software tools supplied with the
equipment facilitate simple subsequent visualisation and processing of the data on the PC.

Sampling and Analytic
It is essential to take water samples to get information on the state of the
water or aquifer. This task makes very high demands both of the people
processing the information and the sampling devices so that conclusive
samples can actually be taken. In hydrology sampling is not, however, merely restricted to the water. Samples of sediment provide information on
the current state and development of a body of water.

Groundwater-Shuttle
The shuttle guard system prevents
vertical currents and the associated danger of substance transportation, thereby permitting longterm undistorted sampling.
The system can easily be retrofitted in existing, regularly developed groundwater measurement
points and can also be dismantled
again without causing damage. Unlike special measurement
points and installations which
are associated with considerable
costs and which usually only allow sampling of a restricted depth
range with removal of small sample quantities.
GW-stations
The system comprises two parts:
•.Groundwater station (GW station) to separate the groundwater area from the affected stagnant water
• Groundwater shuttle (GW shuttle) for isobar sampling under in situ pressure
The PVC groundwater (GW) station has been designed for permanent installation in a measurement point, but can also be easily
removed again for maintenance
work. It has two inflatable packers
which permanently seal the filter
area of the groundwater area that
water flows through to protect
this against the stagnant water
above and below it, thereby preventing substance transportation
between aquifer and stagnant water or atmosphere. To do this, the
GW station is positioned in the

The water sample is conveyed at
the corresponding water depth
into the pressure-retaining, replaceable sample container, maintaining the ambient pressure. Even
during the inflow of water there
is no serious change in pressure
here. Degassing and precipitation
processes are avoided.
The GW shuttle is then undocked
from the GW station and moved
out of the measurement point.
The filled sample container is removed. If necessary the sample
can be taken all the way to the laboratory in the container maintaining in situ pressure. A new sample container is inserted in the GW
shuttle to take another sample.
Advantages
However the filter length should
not exceed 10 m.
The GW shuttle must only be procured once. It can serve all GW
stations. Additional sample containers are recommended depending on the required number of
samples and frequency of sampling.

Every groundwater measurement
point must be equipped with its
own GW station which permanently protects the aquifer and
is available at all times for taking
samples. The modular design of
the GW station enables simple adaptation to the filter length of the
groundwater measurement point.
blank
The shuttle guard system permits the removal of groundwater samples from an undistorted
area of groundwater. Distortions
even arise in regularly developed
measurement points due to vertical currents in the water column
(through unavoidable vertical
differences in pressure, temperature and/or substance concentration). The associated substance
transportation has effects on the
geochemical composition of the
sampled water and/or the correct
assignment of the sample to the
depth.
It is not possible to obtain a representative groundwater sample reliably using classic methods where
there are vertical currents.
To take a groundwater sample
the GW shuttle is lowered into
the measurement point where it
docks onto the GW station. There is no need to pump water from
the groundwater measurement
point because the GW station separates the filter area from the
stagnant water. For a perfect sample the connection path between
sample location and sample bag is
first rinsed with fresh groundwater after docking. Only then does
sampling take place.

Sedimentation traps
AQUA-CHECK 2
The sedimentation trap is a plate
trap that has been produced by
UGT GmbH under licence from
IGB Berlin, and which is used to
measure the sedimentation of
fine organic and inorganic particles found on the beds of bodies of
water. The defining hydrodynamic
conditions of the beds of bodies
of water are reproduced through
the design and arrangement of
the plate traps, and the sedimentation rates in moving water (e.g.
rivers, shallow seas, seabed, canals and harbour basins) are measured under the effect of gravity
and soil shearing stress.
It consists of a vertically mobile
piston whose upper surface constitutes the collecting surface.
When the water charged with
sedimentary particles sweeps
past the upstream approach rim,
a boundary layer develops under
the impact of shearing stress similar to that at the bottom of the
water. The particles settle on the
collecting surface in relation to
these conditions. A rigid roof connected to the piston protects the
deposited sediment from external
influences.
At the end of the exposure period
the deposited material is transported to the inside of the sedimentation trap by lowering the
mobile piston. The roof seals the
sedimentation trap in this position and prevents material getting
lost when the trap is lifted out of
the water. The movement of the
piston is pneumatic. A hand pump
is recommended for simple use
in the field. The hose connection
provided for this has an inner diameter of 4 mm.
The sedimentation trap can be
placed directly on the bottom of
the water or can be positioned at
the desired height in the water
using a mounting rod.
Delivered in its sturdy hard case,
the entire analysis equipment is
well protected, and can be transported with ease on field trips.
The photometer, all necessary indicators, testing tubules, as well
as the timer and safety glasses are
always ready for usage, thanks to
the neat arrangement within the
hard case. Preparatory time for
the measurement is thus minimal.

fully extensible measuring probe,
a broad measuring range is at the
Aqua-Check 2’s disposal. Hence,
even miniscule concentrations of
phosphate can be detected reliably. The Aqua-Check 2 is delivered
with solutions for the titrimetric
determination of total and carbonate hardness by default. Using
the test kit included in its delivery items, a total of 390 individual
analyses can be carried out. Although the pro equipment allows
for environment-independent water analyses, it nevertheless ensures professional measurements.
The Aqua-Check 2 is powered by
a customary 3-Volt coin battery,
which allows for up to 1’000 individual measurements.
Technical data
Technical data
The Aqua-Check 2 is a highly sensitive and portable photometer,
built for the precise determination of substances and there concentration in water. As the device
was equipped to measure a broad
variety of water parameters, it
responds both to industrial demands, and to those of the fishery, aquaculture and koi keeping
sectors.
The Aqua-Check 2 draws upon the
photometric procedure, which is
eminent in physics and chemistry.
The photometer sends light beams
of a defined wave length through
a water sample, which is especially coloured for this procedure.
Using the measured change in intensity of the incident light , the
device can meticulously establish
the concentration of the parameter under investigation. Conventional tests commonly use cuvettes.
However, as they may vary in wall
thickness, or may be subject to
impurities, measured values are
often distorted. In stark contrast,
the Aqua-Check 2 determines
these values without cuvettes, en-

Weather stations
Weather stations are used to record large-scale dynamic processes within
the atmosphere in addition to limited spatial climates such as those for
woods or cities. These processes and the resultant weather dynamics have
decisive influence on the water balance of a region, on the soil, on flora and
fauna and thus also on land use.
The extension of a measurement station to include meteorological sensors
generally generates increased information, permitting a comprehensive
picture of the hydrological, geological, biological or chemical processes.
The equipment on the weather station can look very different depending
on the objective of the application.

Weather station UGT
iMETOS® pro weather station
UGT offers specially customised
weather stations to meet the precise requirements of the planned
use of the weather station. The
core element of these weather
stations is the tried and tested
UGT data logger DL-200. Depending on the project requirement,
sensors for the following examples of parameters can be connected to these data loggers:
• Wind direction
• Wind speed
• Solar radiation
• PAR
• Air temperature
• Air humidity
• Air pressure
• Precipitation
• Soil temperature (optionally
at different depths)
• Soil moisture (optionally at
different depths)
In the following chapters on the
subject of meteorology you will
find a summary of the standard
meteorological sensors offered by
UGT. Other sensors are possible
on request. Equipping weather
stations for specific applications
makes it possible to also record
non-meteorological data such as
soil moisture at the same time.
The measurement data can be
transferred and retrieved from
the data logger using remote data
150
transmission, by USB cable or by
feeding data into a data network.
The efficient energy management
of the logger reduces the energy
requirements of the weather station to a minimum. The energy
supply can therefore be provided
optionally using the mains current
(230V / 50 Hz) with back-up battery to bridge failures in the mains
current with solar panel or using
rechargeable batteries. You can
find detailed information on this
in this catalogue in the section on
“data acquisition and energy supply”.
UGT uses weather station masts
made from high quality V2A stainless steel pipe for reliable installation and minimal influence on
sensors. The ground socket specially developed for this (which

The masts are available in any
length in line with the individual
character of the UGT weather stations, but are generally 2 m long in
accordance with German Meteorological Service guidelines
Umwelt-Geräte-Technik GmbH
The iMETOS® pro weather stations can be equipped with up
to 80 sensors, and can therefore
deal with almost all established
micro meteorological challenges.
The energy supply for the entire
weather station is provided using
solar panels and rechargeable
batteries, so that no mains connection is required on the installation site. All data measured by
your iMETOS® pro are transmitted via GPRS/GSM to the uniform
“field climate” user platform with
password protected access. This
website offers the following options: access to weather data in
the most diverse forms (tabular,
graphics, various averages etc.),
alert programming for SMS alerts
(threshold value changes, entering a telephone number etc.)
and options such as automatic

to other servers.
You can change your parameters
at any time, thereby adapting
your requirements quickly and
individually. This central internet
solution requires absolutely no
additional software on the part of
the user, but merely an internet
access with browser. It therefore has unrestricted potential for
expansion. The field climate platform provides open interfaces

Automatic rain gauge with tipping bucket
This rain gauge with tipping bucket has a magnetic encoder with
reed contact. The tipping bucket
empties automatically each time
it catches rain from 0.2 mm precipitation and triggers an electrical
pulse. These pulses are added together when recording the data.
The data recording can either use
an electronic counter or a 1-channel data logger.
The housing is completely made
of plastic (PE) and all parts are
rust-proof. The surface of the tipping bucket is metallic to make it
more durable. The automatic rain
gauge can be used both in weather stations and as “stand alone” measurement instrument. A
mounting base with adjustment
screws is used to attach the rain
gauge on the installation mast and
also for the horizontal alignment
of the device. A built-in spirit level
can be used to check the horizontal alignment.
Precipitation sensor/ombrometer
This automated rain gauge can be
supplied with an electrical heater to record precipitation in the
winter. The electrical connection
takes place using a 12 m cable
with RJ 11 socket fixed to the sensor. Extensions are possible on
customer request.
This device is used to record readings of precipitation volume and intensity
for digital transmission of these measurements. The measurement principle is based on the description in the »Guide to Meteorological Instruments No. 8« from the WMO. The tipping actions of the tipping bucket are
recorded by a contact and read out via the electronics as a pulse for further
processing using intensity-related linearisation.
This precipitation sensor is made
from weather-resistant stainless
steel and is also available with 49
W and reinforced 113 W housing
heaters. As a result it is especially
suitable for use in mountains.

Temperature and moisture sensors
The temperature sensors introduced in this chapter are in no way purely
meteorological temperature sensors. The chapter also introduces sensors
for soil temperature, because the soil temperature is of great significance
to processes in the soil, to the soil life (the edaphon) and to plants.
Moreover both temperatures can deliver information on the water balance. Because air temperature and air humidity are closely related to each
other, measurement equipment exists with sensor combinations that can
record both of these parameters together.

Radiation sensors
The temperature of the surface of the earth as well as fundamental life
processes of plants are determined by the radiation balance. This describes
the overall effect of radiation, taking absorption and reflection as well as
re-emission and diffusion into consideration. Depending on their design,
radiation sensors can record the radiant flux density of specific irradiance
parts or of all irradiance.

CMP 3 pyranometer
This transmitter is used to measure solar irradiance. Due to the
spectral range of 0.31 – 2.8 µm,
the device can also be used as
albedometer in the sense of a
double pyranometer. The CMP
3 is smaller and lighter than other
CMP pyranometers. It has a strong
4 mm glass dome which protects
the thermopile from external influences. Its small size and waterproof construction make this instrument ideal for deployment in
agriculture, for monitoring solar
NR Lite silicon net radiometer
installations, in industrial applications and for use underwater. It
has a screw-on mounting rod for

The CNR 4 consists of two pyranometers and two pyrgeometers
whereby one instrument faces upwards and the other faces downwards. Together they all measure the energy balance between
short wave and long wave (far
infrared) radiation as well as the
Albedo. The CNR 4 is the successor to the familiar CNR 1, and has
considerably improved properties. The CNR 4 is extremely light
and equipped with an integrated
sunshield to reduce the impact
of thermal effects on the measurement. The meniscus-shaped
dome of the upper pyrgeometer
ensures a significantly better measurement of long wave radiation.
The optional CNF 4 ventilation

AIR ANALYSIS
NR Lite silicon net radiometer
Information about air constituents is vital for providing knowledgeable answers to current environmental research issues. In addition to the
„classic” greenhouse gases such as CO2, CH4, CO and H2O which have been
and which continue to be at the centre of attention with regard to global
change, ever more constituents of the air are gaining significance in atmospheric research. Here it is apparent that real time measurements in the
field detect trends more quickly from which forecasts can be derived. To
guarantee this, robust but compact measuring systems are required which
can detect the concentrations and isotope ratios for the most important
molecules up to an accuracy of ppb. Modern equipment with a high temporal resolution in terms of measurement frequencies in the hertz range
are deployed in the most diverse atmospheric „flux” measurements. Measurements with these modern devices are, of course, not restricted to the
field; they can also be used under indoor conditions at any time.

Climate influenced by vegetation
Local climates are greatly influenced by the vegetation found there, just as
vegetation is substantially influenced by the prevailing climate. This interaction is of great interest both to ecology and to meteorology. At the same
time, however, it also represents specific challenges with respect to the
monitoring of meteorological parameters. This is especially the case in the
area of forestry where, due to their size, trees have an enormous influence,
but one which differs in spatial and temporal terms depending on the type
of tree, concentration and season. Tried and tested meteorological measurement procedures are adapted and additional parameters measured to
reliably record the influence of types of vegetation on the climate.

Litterfall trap
The litterfall trap can be used to
obtain samples of fallen leaves,
conifer needles, pieces of wood
and seeds. Important information
can be discovered about the state and process operations of the
ecosystem from the mass of litter
and its temporal distribution. The
chemical examination of litterfall
samples in the laboratory gives an
insight into the nutrient balance
in the ecosystem.
The UGT litterfall trap is funnelshaped with a collecting surface of
500 mm x 500 mm and a ground
surface of 100 mm x 100 mm.
Rain gully under vegetation
It is made from weatherproof
aluminium and is riveted in the
corner areas. The folds are sealed
with silicon rubber. This design
means the litterfall trap is both
very robust and resistant to falling
branches.
The base frame made from square
steel tubing enables simple installation and keeps the collector in
the correct position. It is fixed in
the ground using two ground stakes. The corrosion coating guarantees a long service life.
An optional strainer insert for easier removal of litter is available.

Deposition sampler
The deposition sampler is used
to record precipitation to analyse the precipitation composition
in the laboratory. Collecting tank
and collection volume are connected to each other by screw
connection. A protective filter
that is overlaid with glass beads
is integrated in the screw connection. This filter system prevents
the entry of coarse dirt and at the
same time avoids condensation
from the collector volume in order to maintain the concentration
of the substances dissolved in the
water.
It is made of PE-HD. The aperture
is restricted by an acrylic glass ring
to guarantee the collecting surface of 100 cm².
By way of standard the deposition
is recorded 1 m above the surface
of the soil in a PVC pipe (Ø 130
mm) that has a ring attached to its
free end to prevent birds settling
on it. However the tiered installation of the deposition sampler is
possible on customer request.

Mobile roof construction beneath the treetops
This individually adapted, mobile
roof construction which is either
manual or automatically controlled by rain sensors has been
designed for targeted irrigation
scenarios (e.g. drought stress trials) in forests, also where there is
fully grown vegetation. The trunks
of the respective “covered” trees
are integrated in the roof structure; the stemflow is collected
using elastomer collars (see also
UGT stemflow meter) and conveyed away on the roof. The rainwater obtained in this way can be
collected and examined or used
for targeted spray irrigation.
Depending on the respective vegetation situation, 80-90% of the
entire roof surface made from
special transparent UV-resistant
film across piping rails can be constructed so that it can be moved.
The remaining 10-20 % is permanently closed. The special construction, which can be compared
to a “pagoda roof”, enables a vertical and horizontal exchange of
air even when closed.
Advantages
•Keeps substance concentration

sampling. The measurements can
be consistently recorded using a

As a result the micro climate of
the crops is only slightly disturbed
and problems caused by “stagnant air” such as mould are avoided. The entire roof construction
has a modular structure and can
be extended almost indefinitely
from a minimum size of 2 m².
The materials used are aluminium, PE foil and stainless steel, as
well as small quantities of diverse
plastics and galvanised components. In order to be able to completely rule out the entry of zinc
into the soil, special solutions without galvanised components can
be offered on request. The roof
construction can be expanded by
a camera system for monitoring of
the sample area.

Rainmaker
IDS-Plant
The Rainmaker is a flexible overhead irrigation system for use in
the field, which has been developed in collaboration with the
soil and water protection working
group at the technical university
TU Bergakademie Freiberg. Using
this system, precipitation events
of varying intensity can be simulated over areas of 1 m² to 3 m².
Enclosing the measuring station
using the corresponding stainless
steel frame enables the surface
runoff and eroded soil material to
be captured.
The system has a modular design,
made from an adjustable base
frame and individual sprinkler
heads. Each sprinkler head covers
a test area of 1 m². For larger test
areas, up to 3 sprinkler heads can
be combined into one overall system for a maximum measurement
area of 3 m². The enclosed size of
the measuring station can be adapted accordingly. Swivel nozzles
in the sprinkler heads distribute
water from a tank evenly onto the
test plot. The height of the sprinkler heads can also be adjusted on
the frame. This makes it possible
to change how far the water falls
and also facilitates use in uneven
or sloped terrain, because the
sprinkler heads can always be aligned horizontally. The telescope
function of the legs of the frame
enables a fast and simple rough
adjustment, which is then the
basis for the precise alignment
of the system. The accurate, fine
alignment of the sprinkler heads
can be achieved using the spindle
drive on each of the legs.
The system can be completely
dismantled for transport, thereby enabling it to be used at different measuring sites. The sup-

As required, the control unit can
be designed as a portable, selfsufficient system or as a stationary

port frame and mountings of the
sprinkler heads are manufactured
from anodised aluminium for minimum weight and high robustness. The hoses can be disconnected and connected using quick
connectors. All cables have separable connections using couplers
with protection class IP65.
Tarpaulins can optionally be
mounted on the device support to
prevent the influence of wind.
The entire peripheral equipment
of the irrigation system can be
freely selected. For example, existing pumps and water tanks can
be used. However it is important
to ensure that both the pump performance and the volume of the
water tank are consistent with
the idented irrigation intensity.
Pumps and water tanks can also
be ordered from UGT GmbH as
required. In this case, the pump
and water tank are selected so
that they produce a complete and
integrated system with the specified intensity.

The distributon elements each
consist of a 200 ml reservoir with
a self-opening and self-closing
valve combination for inlet and
outlet of the medium to be distributed. These valves have no
small passages and thus don`t get
clogged. Therrefore the system is
also suitable for the distribution
of ferrous or calcic groundwater,
polluted surface water, biologically preclarified wastewater and
fertilizer. Further also plant effective gases such as CO2 can be
applied with the distribution elements. Additional filter systems
are not necessary.
The swivel speed and the dwell
time of the nozzles can be adjusted at the terminal point via a
control unit with LCD display in order to regulate the simulated precipitation intensity. For independent operation, the energy supply
to the control unit is by means of
a storage battery.
Advantages
•Flexible
•Transportable
•Adjustable precipitation intensity
•Even irrigation due to moving
The application is carried out in
a pulsed manner in three clocks:
Pulse = filling clock + draining
clock + pause clock
During the filling clock, the medium is pumped into the reservoir
by the control unit. Thereby the
air in the reservoir is compacted
so that an overpressure builds
up in the system. When this pressure reaches the limit set on the
control unit the emptying clock
starts. The hose system between
the reservoirs is vented so that
the pressure drops. Thereby the
outlet valve of the reservoir is
opened and the compressed air
pushes the medium out. The reservoir is completely emptied.
Through this control technology
all reservoirs connected by tubes
open at the same time and apply
the same amount of the medium
independent from their position
in the overall network. With the
pause clocks the time for the start
of the next pulse is controlled. The
pause clock can be set as a given
time interval or via a given tension. This way the pulse frequency
can be optimally adapted to the
demand of the plants.
In adjustment to the planned
application the distribution elements can be designed in different ways (e.g. as jet or distributer
hose).
Leakages in the system are automatically detected by the control
unit instantly since in that case
the designated pressure is not
reached at all or not within the
set time.
The system therefore offers a high
dosing accuracy and high operational reliability with minimal maintenance.
Advantages
•Parallel application of water, additives and CO2
•Low maintenance effort
•No clogging of the distribution elements
•No filter systems necessary

•High operational reliability

The photosynthesis processes in
plants and the biomass production depend heavily on solar radiation. For this reason data on the
PAR (“photosynthetic active radiation“) are of great significance if
the ideal light conditions for maximum yields are to be determined.
The SunScan system supplies such
data and is suitable for measuring and analysing the PAR in the
leaf canopies of crops. The SunScan package consists of a light
incidence probe, data acquisition
module and software. The probe
can also be supplied separately if
data acquisition systems are already present. The probe is 1 m
long and contains 64 PAR sensors
which are read out during every
measurement.
Connection to a data acquisition
module uses the RS232 interface.
Fast and accurate measurements
can be taken using the control
button on the probe handle. Using
the data acquisition module the
probe is programmed for automatic measurement at intervals ranging from 1 second to 24 hours.
The data module reads out the
readings and calculates the average light level of each individual
sensor. The individual readings remain in the memory, which enables an additional, more detailed
examination of the PAR. The raw
data and the derived functions
(light transmittance/LAI) can be
collated, stored and displayed.
Average values for groups of readings can be created, and vari-

Dendrometer
The dendrometers presented here are used to determine the circumference, radius or diameter of plants. It has long been the case that not only
trees are measured, despite the actual meaning of the word (tree measuring device). Modern dendrometers are becoming ever smaller, lighter
and more accurate, which makes them suitable for an ever larger range of
applications. For example special dendrometers can also be deployed for
agricultural crops and fruits. Electronic dendrometers used in combination
with data loggers permit the recording of entire hydrographs of the plant
diameter over days, months or years so as to be able to make statements
about the growth and conduct of the plants and the influence of correlating environmental factors.

DB20 manual band dendrometer
Manual band dendrometers are
frequently deployed in commercial forestry and research. They
are an extremely reliable and inexpensive method of precisely
measuring and monitoring tree
growth rates. The tree growth
rate already makes it possible to
gain sufficient insight into many
issues, such as those in the area
of commercial forestry. In addition to this, tree growth rates can
also be combined with sap flow
data to correlate the respective
water use or water consumption
with the growth rate.
The DB20 band dendrometer
consists of a fixed and a sliding
DRL26 logging band dendrometer
scale which is held in position by
a spring. By cutting the band, the
DB20 band dendrometer can be
individually adapted to the respective tree circumference, and is
then held in place by spring tension. The tree growth in the form
of increased diameter can be read
off the sliding scale manually in
0.1 mm steps.
The water balance of an entire
tree can now be examined more
easily and more accurately. The
logging band dendrometer has
its own, internal data logger. The
integrated lithium battery means
that no external batteries or solar
cells are required as energy supply
for the logger. As a result the dendrometer can be fixed to a tree
without any other accessories.
This individualised measurement
enables the most diverse range of
trees in a large study area to be
sampled because there is no need
for connection to a central logger.
This makes it easier to conduct
studies with large spatial distribution, e.g. different growth or age
structures.
The DRL26 dendrometer is a very
reliable and inexpensive method
of precisely measuring and monitoring tree growth rates.
In addition to the long-term
growth, the recording of changes
in the stem diameter with a resolution of 0.001 mm permits observation of everyday fluctuations in
the trunk tissue that are a reac-

This sensor for recording the tree
trunk growth is particularly distinguished by its stable installation.
It is anchored in the heartwood
using two screws and in this way
measures the change outside the
heartwood as radial growth.
This arrangement guarantees
both that long-term measurements are very stable and that the
fastening is secure. There is only
very little counter pressure created on the measurement point its-
elf so that the radial growth is not
obstructed by the sensor. Damage
to the tree caused by the necessary drilling can be minimised using
tree resin. The instrument is connected to an external data logger
to record the data. This enables it
to also be connected to an existing data logger to expand existing
measurement stations. The radius
dendrometer is supplied with 2 m
of cable as standard. Cable extensions are available on customer
request.

changes (e.g. daily variations).
The data on daily trunk tissue fluctuation can be combined with sap
flow data on the same tree to improve correlation between water
consumption and understanding
about the functional hydrology of
the tree and/or specific treatment
measures.
The DRL26 is a non-invasive measurement system with a rotary position sensor for infinitely variable
measurement of the trunk diameter and the growth of the tree studied. The memory card installed
in the data logger has capacity
for 50,000 readings. This means
data storage of over 4 years with
storage at hourly intervals. In this
case the internal lithium battery
provides an energy supply for 5
years. The logger has an environmentally friendly seal, and communication takes place via an infrared interface. A sophisticated
MS Windows-based software package facilitates configuration of
the logger and detailed statistical
data analysis.

Umwelt-Geräte-Technik GmbH
The DC2 is the improved version of the DC1 for measuring
the changes in circumference of
trees without damaging them.
The change in circumference is
determined via the tensile force
of a metal wire that is clamped
round the tree being measured.
Slide rings tubes reduce the friction between the wire and bark
and reduce pressure on the measurement point. For trees that are
predominantly round the pressure data obtained can be directly
converted using the corresponding Excel program. The pressure
sensor supports itself and does
not need to be held by the steel
wire. Owing to the special tensioning system, the pressure on the
tree is unrelated to the tree size.
For this reason the data from different sizes of trees can be easily compared using the DC2. This
dendrometer supplies sensitive
readings even for very large trees
because the tensile force of the
wire is automatically adjusted.
The DC2 is supplied with a 2 m
cable and 1 m wire cable, but
can also be supplied with special
lengths of cable and wire on customer request. Data are recorded

Sap flow and water potential
The water balance of an ecosystem is largely influenced by the water balance of the corresponding plants, while in turn this plant water balance is
influenced by the ecosystem itself. An understanding of these interaction
processes therefore forms the basis for water balance examinations and
for studies of plant physiology.
Sensors measuring sap flow record the transportation of water in stems or
branches. The aim of today’s technology is to cause as little damage to the
plant as possible and ideally none at all and to influence the transportation
process as little as possible. The water potential of the plants can be determined both on woody parts and on leaf samples using psychrometers.

Stem psychrometer
Stem psychrometers are used to
record the plant water potential
of living plants without damaging
them. Compared to more commonly deployed leaf psychrometers, they offer the advantage of
being considerably easier to attach. This minimises disruptions
to the energy balance which in
turn improves the overall measurement accuracy.
The stem psychrometer consists
of two welded, series-connected
chrome contantan thermocouples inside a chrome-plated brass
chamber, forming a large insulating thermal mass. One thermocouple is in direct contact with
the test stem, while the second
simultaneously measures the air
temperature in the chamber and
then serves as a wet bulb thermometer. A third, soldered copper
constantan thermocouple used
for temperature compensation
is situated inside the body of the
sample chamber to determine
its temperature. All temperature
measurements are entered into
the calculation of the plant water
potential.
The stem psychrometer is attached to the stem by clamps
using light pressure. These clamps
are available in two sizes for stem
diameters of up to 2 cm and up to
Field plant water status console
approx. 5.5 cm. The psychrometer
can also be attached to thicker
stems using special solutions. The
measurement can be either psychometric (wet bulb thermometer measurement) or hygrometric
(measurement of dew point) and
consistently permits the production of precise and reproducible
measurement of the plant water
potential with the help of automatic correction of the temperature
gradients inside the measurement
chamber. With good thermal insulation the setting half-time can be
reduced to 60 seconds, making
this a very fast and reliable instrument. Every stem psychrometer
contains a Smart Sensor Interface which converts the microvolt
measurement signal into calibrated stem water potential. The
integrated microprocessor keeps
the selected calibration equation
and measurement frequency in
the memory and provides regulated excitation voltage and the
Peltier cooling current so that no
complicated programming and
wiring of the sensor is necessary.
In conjunction with the ICT Smart
Logger, use of the stem psychrometer can be flexibly adapted to
various operational objectives in
an accurate, user-friendly and efficient manner.

HFD sap flow sensor
The Heat Field Deformation (HFD)
technology is ideal for measuring
radial sap flow profiles. This tool
can therefore be used to create
a hydraulic “map” of the tree architecture. High, low and negative
volumes of sap flow can be determined using the HFD sensor technology. HFD measurements are an
ideal supplement to SFM-1 measurements.
The HFD technology is a thermodynamic method based on measurement of the temperature
gradients in axial and tangential
direction inside the sap wood
with reference to a linear source
of heat.
The heater needle is heated at a
constant level of approx. 50 mA,
generating an elliptical heat field
under zero sap flow conditions.
This becomes more markedly deformed the more strongly defined
the current sap flow is. The symmetrical temperature difference is
used to measure the bidirectional
flow in the case of very low flow
volumes, while the average and
high sap flows are determined
using the asymmetrical temperature difference.
The HFD sensor consists of three
measurement needles in combination with a heater needle. These are integrally connected to the
Smart Interface based on a digital
24 bit microprocessor.
The sensor is exclusively compatible with an SL5 Smart Logger on
which the dT symmetric (dTsym)
SFM-1 sap flow sensor
and dT asymmetric (dTas) values
are stored in °C for every radial
measurement by all measurement needles.
206
A short heat pulse is the tracer
for this thermometric method of
measuring sap flows in xylem tissue. It is possible to calculate the
quantity and direction of the sap
flow from the ratio of the amount
of heat transported to two symmetrically arranged temperature
sensors.
Each HFD Sensor includes a precision voltage regulator to control
the heater voltage between 0 and
12 V in 0.01 V increments. The
voltage can be adjusted independently of other sensors in order to
ensure complete freedom when
designing experiments. The voltage can be adjusted simply via the
sensor setup menu either directly
using a wired connection or wirelessly using a wireless modem.
The HFD sensor has a maximum of
8 measurement points along each
needle, and therefore 24 measurement points on all three needles. On the sensor setup menu the
user can set the number of measurement points to be used on the
needle from 1 to 8. The data are
recorded in °C and downloaded
as ASCII file, then imported into
the HFD software. This automatically detects the correct number
of set measurement points per
set of needles and calculates the

The sensor consists of three
35 mm long needles connected
to a 16 bit microprocessor. The
top and bottom probes each have
two thermistors. The third probe
is positioned centrally; it is heated across its entire length and is
a linear heat source, generating a
constant heat pulse along the sap
wood.
The integrated microprocessor
is the heart of the fully automated, plug & play capable sensors.
It controls all operating settings
and sensor calculations, converts
analog signals to calibrated values
and reads these out via the serial
interface. Program variables such
as heat pulse interval, energy input, distances between probes
and measurement frequency are
stored in the memory.

Leaf physiology
The state of a plant and its reaction to environmental conditions can frequently be first perceived from the leaves, although this often only becomes actually visible after a long time. Such changes can be detected quickly
using parameters such as the chlorophyll content of the leaves, the stomatal conductance, CO2 content or oxygen partial pressure. These data are
not only used to determine the current state of the plant, but also serve as
a basis for optimised cultivation to substantially boost the harvest.

LCi-SD photosynthesis measurement system
The LCi is an ultra compact photosynthesis measurement system.
Measurement takes place using
a newly developed miniaturised
analyser for infrared gas analysis
(IRGA) which is housed in the plant
leaf chamber. The leaf chamber
permits very accurate and reliable
CO2 and water vapour measurements for various types of plants.
The LCi is an open system. No large external volume is required because a new buffer application is
used that compensates for fluctuations in the concentration of CO2
in the surroundings.
LCpro-SD advanced photosynthesis measurement system
There is also automatic atmospheric pressure and temperature
compensation for all CO2 measurements.
The LCpro-SD is the smallest, lightest and most inexpensive system
for measuring photosynthesis,
permitting complete control of
environmental conditions. It offers complete, automatic and independent control of the environmental conditions inside the leaf
chamber. The automated control
of conditions is possible both above and below ambient values.
The device is operated using a
control console which has a number of buttons, a large LCD display
and a range of user-friendly menus with which the user can access numerous parameters. Data
are stored on removable SD memory cards. Measurements can
either be started from the control
console or using a push button on
the leaf chamber.
The recorded data can be exported via a USB interface or using
direct transfer from the SD card
to a computer. The data format
is compatible with usual spreadsheet software. In addition to the
standard leaf chamber (broad
model), leaf chambers for narrow leaves, small leaves, conifers,
small canopy growth (e.g. lawn),
whole plants, fruits and soil respiration are also available.
Weighing just 4 kg, the LCpro-SD
has less than half the weight and
half the size of conventional systems offering microclimate control. Nevertheless the space-saving LCpro-SD console has almost
unlimited storage capacity and offers flow control and full programmability.
The set consists of:

A range of interchangeable heads
is available to ensure the system

can be exchanged easily, also during use in the field. Boundary layer resistance and concentration
gradients are minimised irrespective of which head is used. All of
the measurement chamber materials have been carefully selected
to guarantee minimum interaction with H2O and CO2. All windows are silicon-coated to reduce
scratching. The various measurement chambers (broad, narrow
and the special conifer chamber)
each have an individual light source with red/blue LEDS. The light
source is designed to supply PAR
with high intensity and an even
spectrum but with little heat loss.
All real-time photosynthesis data,
calculations and graphs are presented clearly on a large HD LCD
display. In addition to the classical photosynthesis and transpiration calculations, the LCpro-SD
also provides calculations on soil
respiration including NCER when
the soil chamber is used. Data

AP4 porometer
The stomatal aperture is the dominant factor in the diffusion
conductance of leaf surfaces; this
regulates both the loss of water
from leaves and the absorption
of CO2 for photosynthesis. The
measurement of diffusion conductance is therefore an important indicator for the plant water
balance and provides a valuable
insight into plant growth and adaptation of the plant to the respective environmental conditions.
The AP4 measures the diffusion
conductance by comparing the
precise rate of humidification
within a small cuvette to readings
obtained on a calibration plate.
This plate has 6 settings for diffusion conductance whose values
have been accurately determined
using finite element analysis.
MINI-PAM-II
The information cited on the accuracy of other porometers and
gas analysis systems is based on
time-consuming laboratory arrangements and calibration procedures which bear little comparison to operating conditions
in the field. By contrast the AP4
features simple, direct calibration
in the field in line with a tested
physical standard. The special leaf
chamber minimises leaf stress
and therefore unwanted stomatal
closure. The light and ergonomic
sensor head, the large and clear
LCD display and complete QUERTY keyboard also ensure that it is
extremely user-friendly.

The robust chlorophyll fluorometer is suited for routine analysis
of photosynthesis in the lab and
outdoors. An internal computer
provides a multitude of options
which are controlled by a fieldreadable b/w touchscreen. Also,
operation via a Windows PC is
possible. The device is specialized
to measure the photochemical
efficiency of photosystem II (ФII).
In conjunction with a 2035-B leaf
clip, the quantum flux density of
photosynthetic radiation at leaf
level (in units of µmol s-1 m-2) can
be measured. The latter data together with the ФII permits the
calculation of photosynthetic
electron transport rates.
The fluorometer is equipped with
a red LED that maximally emits
at 654 nm (alternatively blue,
474 nm). By means of microsecond timing, the same LED can
emit weak measuring light, continuous light up to 3000 µmol s-1m-2
or very strong light pulses up to
6000 µmol s-1 m-2. Also, the device
provides a far red light source to
specifically excite photosystem I.
Fluorescence is detected by a
photodiode.
AA Mignon batteries provide
power in the absence of external
electricity. An optional accessory is the 2035-B leaf clip which is
equipped with sensors to measure light intensity, leaf temperature
and relative humidity. Further
add-ons are dark leaf clips to determine FM und F0 under day light,
and a thermostattable cuvette

JUNIOR-PAM
The JUNIOR-PAM is the chlorophyll fluorometer used in
teaching. The inexpensive instrument for teaching in schools and
universities can be operated using
just a notebook. The device measures pulse amplitude modulated

which makes it possible to examine photosynthesis under natural light conditions. Using the
“saturation pulse analysis” it is
easy to establish the photosystem

both for studies on rapid fluorescence kinetics and for saturation
pulse analysis. Its compact design
makes the fluorometer mobile
and therefore suitable for use in
the field. In conjunction with a
suitable light sensor (2030-B leaf
clip accessory) it is possible to
estimate the linear electron transport through photosystem II.
The internal light source generates
blue modulated excitation light
with maximum emission at 465
nm and two modulation frequencies (5 and 100 Hz) or blue actinic

The chlorophyll content is an indicator of the health of the plant
and can be used to optimise the
time and extent of additional fertilisation measures; this brings increased yields and improved quality while simultaneously causing
less environmental pollution. The
konica Minolta SPAD-502Plus conducts a fast measurement of the
chlorophyll content in leaves without damaging the leaf. The measurement is carried out simply by
enclosing the leaf with the sensor
head. Because the leaf is neither
damaged nor needs to be cut off
for this procedure, the same leaf
can be measured again later as
the plant grows. Up to 30 measurements can be stored in the memory and displayed as trend curve, indicating changes in readings
over time and revealing abnormal
values at a glance.

Lysimeter technology
The knowledge of water balance and the transport processes between atmosphere, plants, soil and soil life through to ground water and the resultant interactions is the focus of ecological as well as agricultural, forestry
and water-related questions time and again. Modern lysimeter technology
offers the possibility to investigate all these aspects parallel to each other,
always with the highest priority placed on conditions which are as natural
and undisturbed as possible. UGT has a large and constantly growing repertoire of lysimeter technology along with the know-how collected over
15 years of experience in this specialised area to be able to cater to all
requirements.
Only a brief overview may be provided in this catalogue. Our special brochure entitled “Novel Lysimeter Techniques” provides further detailed information on the functioning of lysimeters, the techniques of obtaining
and retrieving samples, our range of standard and special lysimeters, past
and current projects and we would also be happy to advise you personally.

Lysimeters are an important way
of determining the water balance
for ecosystems using water balance parameters. In addition to
the quantity, it is also possible to
investigate the quality of seepage
water. Soil monoliths of defined
dimensions are taken from their
natural environment and given
defined boundary conditions.
In combination with corresponding measurement technology, it
is possible to investigate the function and mode of action of eco
systems in this way. The results
can be transferred from small
to large scales and are amongst
other things a good method to
determine the evapotranspiration of a defined area (typically 1-2
m²), of the water and solute transport in a defined volume (typically
1-5 m³) and the degradation and
conversion of substances under
weathering influences. Due to the
possibility of long term outdoor
investigations under real location
226
Container Unit (Polyethylen PE-HD)
conditions, statements may be
made using lysimeter tests on the
water balance of certain climate
scenarios, for example.
Other possibilities are the comparison of several similar lysimeters
in areas with different weathering
conditions or the comparison of
different soil types or different vegetation with the same weather
over a longer time period. These
investigations provide the foundation for many models to estimate
the effect of climatic change, the
spread of contamination in the
soil or the success of re-conditioning measures. Typical areas of
use for lysimeters are agricultural
land locations, forest locations,
landfills and post-mining landscapes as well as areas with existing waste deposits in need of recultivation.
The combination of several lysimeters is recommended for statistically verified statements.
Up to 4 lysimeters may be put to-
gether in autonomous lysimeter
stations made of PE-HD. For larger
test setups several stations can be
combined or large lysimeter systems erected with concrete basements.
In addition to the outdoor lysimeters, there is also the possibility
to operate lysimeters in column
experiments under laboratory
conditions. These lysimeters are
typically smaller and are used to
investigate the behaviour of natural soils or vegetations under special environmental conditions, as
well as physical/hydrological soil
properties of manually imported
soils or processes of (contaminant) substance distribution, relocation and leaching.
The size of the soil monoliths can
vary from very small dimensions
(95 cm² in area, less than 1 m
deep) through to large lysimeters
(2 m² in area, up to 3.5 m deep).

for mineral soils
Patent No.: 10 353 485; 10 2011 006374
for organic soils and peatland
Soil columns can be sampled with
a high degree of precision and undisturbed soil structure without
the use of heavy duty equipment
using the unique sampling technology for mineral soils developed
and patented by UGT.
The sampling device guarantees
a vertical passage of the lysimeter vessel down to the sampling
depth of the soil monolith and
cuts the contour of the soil monolith using a milling device which is
guided concentrically around the
lysimeter vessel. Due to the cutter
on the face of the lysimeter vessel, the final contour of the soil
monolith is formed. The lysimeter vessel accommodates the soil
column to shape. Only low axial
forces are required to cut the lysimeter due to reduction of the
sheath friction. The soil monolith
is not deformed during extraction
and keeps its natural structure.
For quality assurance purposes,
the cutting process is monitored
by a remote camera.
On reaching the sampling depth,
the soil column is separated from
the surrounding soil area by a cutting device.
After extraction of the monoliths,
the soil profile in the extraction pit
is undisturbed and easily visible.
This permits a good assessment
of the soil profile in the lysimeter
vessel and the taking of soil ring
samples for laboratory investigations into soil properties.
After the monolith has been completely cut, it is held in place by
the profile holder on the cutting
device, acting as a temporary seal
of the lysimeter vessel so that the
monolith can be lifted safely from
the sampling pit after cutting. Xray and computer tomography examinations of the soil columns extracted using this technology have
shown that no cracks or structural
changes occur within the monoliths using this method.
All in all the use of lightweight
technology impairs the extraction
point only minimally and no special requirements are placed on
the properties of the ground. Furthermore, this method of extraction is very space-efficient so that
the surrounding area is influenced
as little as possible when extracting the soil columns.
Special lysimeter vessels and patented sampling technologies
have been developed for the challenges presented by organic soils
particularly in bog land. Large organic soil columns can be investigated using the Moor Lysimeter.
For this purpose, the lysimeter
vessel is trough-shaped, 4 m long,
A diameter of up to 200 mm traditional column shaped monoliths
can be obtained by vertical cutting
using a new extraction technology. The peatland column cutter is
made of an easily adjustable basic
frame, a cylindrically formed, rotating cutting tube and the tubular cartridge to accommodate the
cut soil body.
Ground anchors guarantee the
stability of the device also on
swampy soil. The cutting element
on the lower side of the cutting
tube cuts through the vegetation
top layer and also any organic deposits such as roots, without shifting position. This maintains the

This vessel is lowered into a starting pit to extract the soil monolith from where it is horizontally

In order to minimise the destruction of the soil, the soil monolith
is precut by means of a cutting device on the face side of the vessel.
After completion of the extraction
process, the lysimeter vessel is
lifted from the pit and sealed for
transportation such that the soil
cannot shift.

Lysimeter station types
There are a variety of materials
to house the lysimeters for the
installation of a station. Firstly, it
is possible to build lysimeter basements from solid concrete which
are usually the choice for large
installations. But the construction
of concrete shafts is also possible
for individual lysimeters. These
are then composed of individual
concrete rings. A good alternative here is hermetically sealed PEHD container stations which have
many advantages over the concrete structure. They are absolutely
water proof and gas tight. PE-HD
is also not only distinctly lighter
but also more stable than concrete which considerably simplifies
the transportation and installation. Unlike concrete, the plastic
can also be used in contaminated
and aggressive media. Contrary to
the lysimeter shafts from concrete
rings, the basement integrated in
the PE-HD stations permits simple access to the lysimeters and
therefore unproblematical and
comprehensive maintenance.
230
In special cases, the possibility
exists to integrate metal housing
(usually stainless steel).
Lysimeters are available in different specially adjusted versions
depending on the different tasks.
We offer weighable and nonweighable lysimeters, Forest Lysimeters which can also be used
with tree stock, Groundwater Lysimeters in which the water level
can be controlled according to
real conditions or scenarios, Hillside Lysimeters adapted to the
inclination of the ground, Moor
Lysimeters for use in peatland and
Laboratory Lysimeters for column
experiments in different dimensions.
The efficacy of green roofs and
railway lines has recently assumed
greater importance for ecological
urban planning. UGT has also developed special Roof Lysimeters
and Urban Track Lysimeters for
these experiments.
Greened roof with Roof Lysimeter in
the front
Following long term experiments
it may be of interest in individual
cases to consolidate the data obtained by examining the lysimeter
soil. Year-long influences of microbial processes, the penetration
of roots and substance transportation play a decisive role in the
structure of the soil. Furthermore,
soil changes in the lysimeter compared to the reference soil at the
extraction site can be recorded. A
condition for these experiments
is the extraction of the soil monoliths from the lysimeter vessel
which is as gentle as possible.
UGT has developed a special patented cable cutter, the “lysimeter
soil retriever” (LSR) for this difficult task. A diamond cable cuts
along the inside wall of the lysimeter vessel, thereby loosening
the entire soil column from the
lysimeter vessel. Only a maximum
of 1 cm at the edge of the soil monolith is discarded as a result of
precutting. A hydraulic pushing
device beneath the soil plate then
makes it possible to push up the
released soil monolith virtually
without any deformation. A second cutting device is attached to
the top side of the lysimeter ves-

sel to cut soil slices of the required
thickness, e.g. at the horizon borders from the soil column. In this
form the lysimeter content is still
essentially undisturbed but easy
to access and can be transported
even to a laboratory for further
investigation.
As a result of this form of retrieval, the upper layers do not need
to be destroyed to examine the
lower layers. After retrieval, the
lysimeter vessel can be refilled
and used for further lysimeter experiments.
Advantages of the retrieval technology:
•Facilitates detailed examination of the soil inside the monoliths
•The soil column is impaired during retrieval only minimally around
the edges

Lysimeter technology
Measurement and control technology
In order to exploit the full potential of our lysimeters for comprehensive and precise data acquisition, we have also developed the
requisite measurement and control technology.
The foundation for the water
balance analysis is provided by
weighing the lysimeter. This is
done using the precision weighing
system from UGT with weighing
monitor. Even the smallest water
increases such as dew or frost on
vegetation can be recorded using
this system. The quantity of the
water flowing off on the lysimeter
bottom, and the quantity of the
water samples obtained using the
suction cups is determined using
the tipping counters attuned to
the throughput to be expected.
Water samples can be taken from
any depth in a time- and tensioncontrolled manner using our suction probe systems.
UGT has a broad repertoire of high
performance sensory technology comprehensively presented in
the chapters “Tensiometers”, “Soil
moisture meters” and “Temperature sensors” of this catalogue for
the measurement of soil moisture, soil moisture tension and temperature at any depth.
The UGT data logger (see chapter
“Data acquisition and power supply” are designed such that this
high bandwidth of sensors can be
simply connected and managed
even in large unit numbers.
Furthermore, after cutting the soil
monolith, the objective of natural
conditions which are as undisturbed as possible is met.
The peripheral conditions of the
232

DryLabLysimeter with mobile roof
monoliths cut from the soil must
be controlled in accordance with
the surroundings or alternatively
with the aspired to scenarios.
This will usually relate to the temperature and the tension on the
bottom side of the lysimeter primarily so that the surface is subjected to the same climatic conditions as the surrounding area.
One exception here is the control in accordance with selective
scenarios for example in drought
stress tests, or comparative measurements.
UGT offers a heat exchanger for
the temperature control on the
lysimeter bottom which transfers
the temperature of the surrounding soil directly to the lysimeter
bottom. With a heating or cooling
system the temperature can be
controlled also independently of
the surrounding soil temperature
such as for climate experiments.
The soil moisture tension of the
surrounding soil is recorded with
tensiometers and then transferred to the lower edge of the soil
monolith by means of a pump system via ceramic cups. Here, too,
the possibility exists to conduct
the control process in accordance
with the scenario irrespective of
the ambient conditions.
PE-HD lysimeter stations can also
stand in ground water due to the
fact that they are water tight. For
this special case the surrounding
water level can be transferred directly into the lysimeter vessel via
a pressure compensation system
with filter. If the ground water in a
lysimeter distant from the ground
water is to be simulated, this can
also be artificially dammed - on
request also in accordance with
the values of the distant ground
water level which can be transferred to the control unit in the lysimeter via a radio modem.
We also offer special solutions for
the control of the water input on
the top edge.
The uncontrolled water input as a
result of rain can be prevented by
a mobile roof which automatically
moves over the lysimeters when
it rains. Since the roof only covers
the lysimeters when it rains, the
influence of the roofing on the vegetation is very low. Rain systems
can be installed for selective fully
automatic watering. In the special
case of a sloped lysimeter, it is
also possible to record the surface
run off. This is captured in a collar, recorded in a tipping counter
and filled into collecting flasks as
required for later investigation or
as an adequate sample.
An Ecotron is a measurement system to investigate ecosystem functions in the soil-plant-atmosphere
system under defined boundary
conditions. Ecotrons are used to
investigate processes within the
soil-plant-atmosphere system as
well as the interactions between
the compartments. Ecotrons are
lysimeter applications beyond the
investigation of only soil processes and thus the generic term for
lysimeter applications of all kinds.
An Ecotron consists of three units.
The lower unit contains the soil,
which can either be inserted directly into the container or in
extra stainless steel cylinders (lysimeters). The latter allows the
investigation of undisturbed soil
monoliths. Up to four lysimeters
can be installed in one Ecotron.
Several soil sensors can be installed in the lower unit to collect
soil temperature, soil moisture
and soil tension data. To investigate root systems and root growth
rhizotrons can be installed as
well. The lower unit is equipped
with a system to collect seepage
water and a system to control the
temperature conditions at the lower boundary of the soil. On top
of the lower unit a second unit is
attached, which isolates the environment above the soil surface
from the surrounding. The size of
the isolated habitat is big enough
for growing of medium shrubs.
The second unit can be equipped
with additional walls to divide the
Ecotron in four self contained sub
units. On top of the second unit
the upper unit is located, which
contains equipment for irrigation, lighting and ventilation. The
upper unit can also be equipped
Ecotron-plant at UFZ Leipzig
with sensors to collect data of
temperature and humidity as well
as with a gas analyzer.
The lower and upper units are
equipped with a control cabinet
containing the required power
supply and signal transformation
as well as the measurement and
control technology. The Ecotron
comes with a touch panel to visualize collected data and to control
the Ecotron.
The equipment and design of the
Ecotrons are always optimized for
the customer-specific research
goal.

Ready-to-go Lysimeter
Lab lysimeter
There are a number of advantages
to studying soil processes under
laboratory conditions: the controlled environment allows more
precise experiments, the scale is
adapted to several processes and
permits shorter test times compared to field studies. Different materials can be integrated quickly.
Laboratory lysimeters can be used
to realise both monoliths and specifically filled columns.
Column experiments on laboratory lysimeters lend themselves
to the examination of physical
soil parameters using multistep
outflow or multistep flux experiments. These can also be used for
measuring conservative or reactive transport.
The Ready-to-go Lysimeter is a
small lysimeter station for soil columns with an area of up to 0.5
m² and a length of up to 1 m. The
Ready-to-go lysimeter is suitable
both for disturbed soil (filled by
hand) and for undisturbed soil
monoliths when using the patented UGT excavation technology.
The compact lysimeter station
consists of a PE-HD lysimeter
vessel with weighing system and
seepage tank with tipping bucket,
a weather station, a data logger
and a range of soil hydrological
sensors. The system operates as
plug and play system, so that the
entire station can be erected and
put into operation without special
tools or specialist personnel. The
data are displayed on the internet
using the SVADSS online data management system.
Up to four Ready-to-go Lysimeters
can be connected to one data logger.
UGT GmbH offers laboratory lysimeters in a range of configurations. It is possible to control the
boundary conditions using a suction base or overhead irrigation,
as well as to configure measuring
probes freely.
Every lab lysimeter system is adapted specifically customized according to the planned project.
Lysimeter vessels made from different
materials and with different dimensions
SOILINSIGHT®
How are the roots growing in the
earth? How fast? What is the movement strategy of worms in the
soil? SOILINSIGHT® makes it possible to observe and measure root
growth during the entire crop cycle. With the University of Lorraine,
UGT GmbH has jointly developed
a new method for observing undisturbed soil in its development.
Here earth and biological elements such as plants or worms
are placed in a mini cosmos.
The device can be connected to a
Windows-based laptop or laboratory PC, and scans images of the
physical structure and biological
components (plant roots, worms
etc.) of the soil.
In contrast to the traditionally
deployed structure stability tests
and soil sampling procedures, this
new device permit the continuous
234
observation of soil without disturbing it.
The Ready-to-go Lysimeter
is the ideal supplement to an
existing weather station
for directly calculating
evaporation.
Advantages
•Inexpensive
•Small, and can therefore be
handled and exported without
large machinery
•Can be installed by the user himself
Digital weighing monitor UGT WM 100
Images of the development of the
soil over a specific period of time
can be combined in a film, which
enables better studies to be made
of the dynamics of aggregation
(using zooming, fast forwarding
etc.).
Lysimeters are weighed at UGT
with three precision weighing cells
of the accuracy class C3 / C6 and
the digital weighing monitor UGT
WM 100 with a large graphicscapable LCD display. The stainless
steel structure made of tubular
steel on B15 concrete base provide a safe base for the weighing
technology. This so-called load
triangle guarantees a stable and
exact installation of the weighing
cells as the foundation for a precise measurement. The weighing
cells are installed with the assistance of shock mounts which are
torque and shear-force free. The
use of shock mounts facilitates
mechanical flexibility of the force
input into the scales. Tensions between the weighing cells through
temperature fluctuations, flection
and vibrations which would lead
to considerable measurement
errors are therefore prevented.
Advantages
•Automated high resolution image
collection
•Undisturbed observation
•Multi-scaling
(from 21 x 30 cm to 50 µm)
•Individual image editing
•Analysis software to quantify
pore size, root length, growth
rate, soil porosity etc.
Umwelt-Geräte-Technik GmbH

In addition to the centralised data
acquisition the new weighing monitor facilitates direct communication with the connected lysimeter.
In the lysimeter mode, measurement curves from earlier measu-
rement periods can be graphically
displayed in addition to settings
and measurement interval changes. Irregularities can therefore be
recognised directly during inspections of the lysimeter.

Thanks to modern logger technology continuous, high resolution data series can be recorded with a minimum of manpower. Data loggers permit
the common recording, storage and management of several sensor outputs of a measurement point. In addition microprocessor-based data loggers control the measurement conditions depending on the current measured values. As a result of constant improvements in power management,
the data loggers are becoming increasingly independent of mains power.
The data acquisition is already completely autonomous for many applications with solar power supply and remote data transmission.

Data logger DL-200
The UGT data logger DL-200 is
a modular compact device with
microcontroller-assisted RAM for
the recording of up to 230,000
measured values thanks to an optimised data memory. It is suitable
for the use in lysimeters, hydrological soil measurement points,
climate stations and many other
applications requiring reliable automatic data acquisition - particularly with measurement points
with a large number of different
sensors because it is compatible
with all commercially available
physical, soil physical and meteorological sensors. It can also be
programmed as process control
system with or without logger
function, whereby the modular
concept ensures a simple, efficient and favourably priced design. If the freely adjustable measured value limits are exceeded
the user can be notified by text
message or email. This prevents
measurement failures or even
damage to the measurement
technology.
The measurement cycle can be
freely selected between 5 seconds and 2 h. The data can be
statistically analysed directly in
the logger over 15 seconds to 10
days.
... Data logger DL-200
The use of a 16 bit A/D transducer with real differential inputs
(resolution: 15µV) permits up to
64 input channels. Up to 64 event
inputs are available via the digital
interface for the recording of date
and time of the events precise to
the second and 16 counting inputs for the time-controlled recording of numerical values (e.g. tipping counter). 4 switching outputs
with up to 16 sensors per output
as setpoint generator form the
foundation for the use of the DL200 for process control.
Configuration and data transfer
takes place by notebook with the
user-friendly software interface
UGTLOG via RS232 or USB interface.

As an option the DL-200 can be
be equipped with GSM modem or
Ethernet TCP/IP for remote data
communication and remote configuration. The device can be operated in situ using the communication unit with LCD display, also
without a notebook.
The intelligent power management places the data logger in a
sleep mode between the measurement cycles from which it
is woken up by signal inputs or
at a set time as well as manually
via the communication unit or by
connection of a data transfer unit
to the interfaces. The resultant
low energy requirement permits
battery operation with replaceable storage batteries as well as
solar power supply for completely
autonomous operation in addition to mains power supply.
Depending on place of use, different logger housings are available.
Our ABS housing with class of protection IP65 provides the ideal
outdoor protection for the logger

technology from the influences
of weather and mechanical damage; it can also be used indoors
such as in lysimeter basements
or laboratories. Alternatively, the
data logger can be housed in a
high quality switch cabinet. This
permits simple access to the logger for the connection of sensors
and protects the logger technology from mechanical destruction.
This attractive and easily accessible housing has been particularly
designed for use in laboratories
and may only be used indoors. A
favourably priced housing version
for very large loggers indoors and
also for use outdoors is provided
by the painted steel housing with
a plastic cable flange plate, with
diaphragm bushings for cables
instead of PGs to minimise installation work.
Portable field data logger DL-200 Mobil
The DL-200 Mobil offers the tried
and tested modular UGT logger
technology in portable form as
8-channel or 16-channel version.
As for the stationary DL-200, the
DL-200 Mobil is compatible with
all commercially available sensors. It is equipped specifically in
accordance with customer requirements. Connection sockets are
provided in the front plates for the
sensors selected by the customer
so that these may be simply inserted in the field. The 512 kByte
memory holds up to 230,000 data
which may be statistically analysed directly in the logger. Configuration and data transfer is realised using a notebook with the
user-friendly software interface
UGTLOG, via USB interface.
As an option the DL-200 can also
be supplied with additional RS232
interfaces. The communication
unit with LCD display permits a
fast and simple review of the recording process. Energy is supplied by an internal storage battery with 3.5 Ah. The intelligent
power management minimises
energy requirements. The data
logger moves to sleep mode between measurement cycles from
which it is woken up by signal
inputs or at a set time as well as
manually via series interfaces or
the communication unit.
The weatherproof light metal casing with handle makes the logger
light and secure and can also be
transported even in difficult terrain.

Logger software UGTLOG
EASYlog data logger
The accompanying software UGTLOG for logger configuration and
data transfer is an ideal utilisation
of the resources of the Data logger DL-200.
EASYlog data loggers are available
as single channel data loggers for
different measurement sizes. In
addition to models for temperature, moisture and temperature/
moisture, a model for process
signals is available which records
voltages (0-2 V and 0-10 V) or
currents (0-20 mA and 4-20 mA)
as well as a model to record pulses and contact signals.
This extensive software is very versatile and can therefore be exactly
attuned to every logger. The user
interface shows all existing modules and slots. The assignment
of the slots by sensors is shown
by characteristic symbols so that
an overview of the current structure and assignment of the logger is provided at all times. Once
the connection has been created
between notebook and logger the
current values of all sensors can
be faded in on the user interface.
Depending on model, EASYlog
data loggers offer a memory capacity of up to 48,000 measured
values. The recording interval
can be set from 2 seconds up to
1 hour. The recording can be started automatically, via a removable electronic key or also if set
limit values are not reached.
The data are read out by a simple
2-wire connection which can have

Umwelt-Geräte-Technik GmbH
The optional equipping of the
data logger DL-200 with a modem
permits the fast and inexpensive
remote transfer of data via GPRS
because the data volume is very
low due to the optimised memory
regimen. The data can be read out
at any time – in connection with
UGTLOG also fully automatically
– using any PC, thereby minimising the staffing requirements of
a measurement point. The logger
may also be configured via GPRS
so that remote maintenance is
also possible in the case of a fault
in addition to remote diagnosis.
If the device is equipped with a
modem, data of other loggers can

also be used as setpoint values
if the logger is used for process
control. Depending on the storage
conditions of the measurement
point, the logger can also be incorporated in an existing network
via a COM interface so as to use all
these advantages without GPRS
connection and the associated
costs.
