/ TECHNOLOGY DESCRIPTION
Vaisala HUMICAP® Sensor for Measuring
Relative Humidity
In 1973, Vaisala introduced HUMICAP ®, the world’s first thinfilm capacitive humidity sensor. Since then, Vaisala has
become the market leader in relative humidity measurements,
and thin-film capacitive humidity sensors have developed from
one company’s innovation into a global industry standard.
Vaisala HUMICAP sensors guarantee
quality and reliability, with their
reputation for accuracy, excellent
long-term stability, and negligible
hysteresis.
How It Works
HUMICAP is a capacitive thin-film
polymer sensor consisting of a
substrate on which a thin film of
polymer is deposited between two
conductive electrodes. The sensing
surface is coated with a porous
metal electrode to protect it from
contamination and exposure to
condensation. The substrate is
typically glass or ceramic.
The thin-film polymer either absorbs
or releases water vapor as the
relative humidity of the ambient
air rises or falls. The dielectric
properties of the polymer film
depend on the amount of absorbed
water. As the relative humidity
around the sensor changes,
4
the dielectric properties of the
polymer film change, and so does
the capacitance of the sensor. The
instrument’s electronics measure
the capacitance of the sensor and
convert it into a humidity reading.

moisture or gas-sensitive materials
– benefit from accurate and reliable
humidity measurements. Measuring
humidity in a critical environment can
be especially challenging.
In the food industry the dryers and
ovens used in bread baking and
cereal manufacture require a carefully
controlled humidity level to maintain
consistent quality and high yield, and
to give distinctive characteristics to
the finished product.

HUMICAP® – The Story of Innovation
Until the early 1970s, hair
hygrometers were commonly
used in radiosondes. At that time,
reliable humidity measurement
was an unresolved challenge
and to solve this, Vaisala began
developing a new type of humidity
sensor using semiconductors
and thin-film materials. The
revolutionary HUMICAP humidity
sensor was introduced two years
later, in 1973, at CIMO VI congress.
HUMICAP was a radical
innovation that changed humidity
measurements for good. The new
technology was groundbreaking:
the sensor had no moving parts,
and due to the advanced use
of semiconductor and thin-film
technologies, it was amazingly
small. The sensor had a fast
response time, good linearity, low
hysteresis, and small temperature
coefficiency.
Despite the fact that the innovation
was designed for a new type of a
radiosonde, the greatest interest
came from elsewhere: people
working in environments as
diverse as greenhouses, bakeries,
warehouses, construction sites,
brick and timber kilns, and

museums. The need for reliable
humidity measurement was
common to all, and instruments
that could do this accurately were
few and far between.
By 1980, a variety of products
based on HUMICAP technology
– from hand-held meters to
industrial transmitters, calibrators,
and other accessories – were
being sold in over 60 countries.
Since its birth, HUMICAP has been
part of Vaisala’s core business,
propelling the company to industry
leadership in the field of humidity
measurement.

How to Choose the Right Instrument for
Measuring Humidity and Dew Point
What is Humidity?
An Introduction
to Humidity
Parameters
Partial Pressure of
Water Vapor
Humidity is simply water in its
gaseous phase, properly called water
vapor. Because water vapor is a gas,
most of the common gas laws apply
to it, including Dalton's law of partial
pressures. Dalton's law says that the
total pressure of a gas is equal to the
sum of the partial pressures of each
of the component gases:
Ptotal = P1 + P2 + P3…
Learn the basics and get the best out of your humidity measurements.
Humidity measurement and control is called for in a wide variety
of industrial applications. Each application has a different set of
requirements for humidity instruments, such as required measurement
range, tolerance to extreme temperature and pressure conditions,
ability to recover from condensation, ability to operate in hazardous
environments, and options for installation and calibration. There is
no single device that is suitable for all needs. In fact, the range of
available equipment is quite large, varying both in cost and quality.
This paper discusses the following
topics in order to help in selecting
the right humidity instrument:
• Different humidity parameters
• Environmental conditions that
influence the choice of humidity
instrument
6
• Sensor properties that influence
the choice of humidity instrument
• Practical guidelines for selecting a
humidity instrument
If we consider air, the equation means
that the total atmospheric pressure
of 1.013 bar (14.7psia) is the sum of
the partial pressures of nitrogen,
oxygen, water vapor, argon, carbon
dioxide, and various other gases in
trace amounts.
Definition of Water Vapor
Pressure
Water vapor pressure (P w) is the
pressure exerted by the water vapor
present in air or a gas. Temperature
dictates the maximum partial
pressure of water vapor. This
maximum pressure is known as
saturation vapor pressure (P ws).
The higher the temperature, the
higher the saturation vapor pressure
and the more water vapor the air
can hold. Thus, warm air has a
greater capacity for water vapor
than cold air.
Effect of Pressure
on Humidity
Dalton's law states that a change in
the total pressure of a gas must have
an effect on the partial pressures of
all of the component gases, including
water vapor. If, for example, the
total pressure is doubled, the partial
pressures of all component gases are
doubled as well. In air compressors,
a pressure increase "squeezes" water
out of the air as it is compressed.
Humidity
If saturation vapor pressure is
reached in air or in a gas mixture,
the introduction of additional water
vapor requires that an equal amount
condenses out of the gas as a liquid
or a solid. A psychrometric chart
shows graphically the relation
between saturation vapor pressure
and temperature. In addition, vapor
pressure tables can be used to see
the saturation vapor pressure at
any temperature, and there are
also a number of computer-based
calculation programs available.
Some humidity measurement instruments allow an individual humidity parameter
to be chosen which can then be followed on a graphical display. This picture shows
different views of the Vaisala HUMICAP Hand-Held Humidity and Temperature Meter
HM70 display.
Relative Humidity
When thinking conceptually of water
vapor as a gas, it's easy to define
relative humidity. Relative humidity
(RH) can be defined as the ratio of
the partial water vapor pressure
(Pw) to the water vapor saturation
pressure (Pws) at a particular
temperature:
%RH = 100% × Pw / Pws
Relative humidity is strongly
temperature dependent as the
denominator in the definition (Pws)
is a function of temperature. For
example, in a room with an RH of 50%
and a temperature of 20°C, increasing
the temperature of the room to 25°C
will decrease the RH to about 37%,
even though the partial pressure of
the water vapor remains the same.
Pressure will also change relative
humidity. For example, if a process
is kept at a constant temperature,
relative humidity will increase by a
factor of two if the process pressure
is doubled.
Dew Point Temperature
Humidity calculators are also available
for mobile phones.
This happens because the partial
pressure of water vapor (Pw) is
increased, but the saturation vapor
pressure is still only a function of
temperature. As pressure builds in
a receiver tank and Pw reaches Pws,
water condenses into liquid and must
ultimately be drained from the tank.
If a gas is cooled and gaseous water
vapor begins to condense in the
liquid phase, the temperature at
which condensation occurs is defined
as the dew point temperature (Td ).
At 100%RH the ambient temperature
equals the dew point temperature.
The further negative the dew point
is from the ambient temperature, the
smaller the risk for condensation and
the drier the air.
Dew point directly correlates with
saturation vapor pressure (Pws ).
The partial pressure of water vapor
associated with any dew point can
be easily calculated. Unlike RH, dew
point is not temperature dependent
but it is affected by pressure.
Typical applications for dew point
measurement include various drying
processes, dry air applications, and
compressed air drying.
Frost Point Temperature
If the dew point temperature is below
freezing – which is the case in dry gas
applications – the term frost point (Tf )
is sometimes used to explicitly state
that the condensing phase is ice. The
frost point is always slightly higher
than the dew point below 0°C as the
water vapor saturation pressure of
ice is different to water. People also
often refer to dew point for subzero
values, even though they mean frost
point. Ask for clarification if you are
not certain.
Parts Per Million
Unit parts per million (ppm) is
sometimes used for low levels of
humidity. It is the ratio of water vapor
to dry gas or total (moist) gas, and is
expressed either by volume/volume
(ppmvol) or mass/weight (ppmw ).
Parts per million (ppmvol) can be
quantitatively expressed as follows:
ppmvol = [Pw /(P - Pws )] × 106
The ppm parameter is typically used
when defining the water vapor content
of pressurized and dry pure gases.
7
Mixing Ratio
The mixing ratio (x) is the ratio of
water vapor mass to the mass of dry
gas. It is dimensionless but often
expressed in grams per kilogram of
dry air. The mixing ratio is mainly
used in drying processes and HVAC
applications for calculating water
content when the mass flow of air is
known.
Wet Bulb Temperature
Traditionally, the wet bulb
temperature (Tw) is the temperature
indicated by a thermometer wrapped
in a wet cotton sheath. The wet bulb
and ambient temperatures can be
used together to calculate relative
humidity or dew point. For example,
the wet bulb temperature is used
in air conditioning applications
where it is compared to the dry bulb
temperature to determine the cooling
capacity of evaporative coolers.
Water Activity
Absolute Humidity
Enthalpy is the amount of energy
required to bring a gas to its current
state from a dry gas at 0°C. It is used
in air conditioning calculations.
Absolute humidity (a) refers to the
mass of water in a unit volume of
moist air at a given temperature and
pressure. It is usually expressed
as grams per cubic meter of air.
Absolute humidity is a typical
parameter in process control and
drying applications.
Water activity (aw) is similar to
equilibrium relative humidity and
uses a scale of 0 to 1, instead of
0% to 100%.
Enthalpy
The Effect of Environmental Conditions
on Humidity Measurement
Select a Representative
Measurement Location
Always choose a measuring
point that is representative of the
environment being measured,
avoiding any hot or cold spots. A
transmitter mounted near a door,
humidifier, heat source, or air
conditioning inlet will be subject to
rapid humidity changes and may
appear unstable.
As relative humidity is strongly
temperature dependent, it is
very important that the humidity
sensor is at the same temperature
as the measured air or gas. When
comparing the humidity readings
of two different instruments, the
thermal equilibrium between the
units/probes and the measured gas is
particularly crucial.
Unlike relative humidity, dew point
measurement is independent

measuring dew point, pressure
conditions must be taken into
account.

Beware of Temperature
Differences
When mounting a humidity probe
into a process, avoid temperature
drops along the probe body.
When there is a large temperature
difference between the probe and
the external environment, the whole
probe should be mounted within the
process and the cable entry point
should be insulated.
When there is a risk of condensation,
the probe should be mounted
horizontally to avoid water dripping
down the probe/cable and saturating
the filter (see figure 1).
Ensure that air is allowed to
flow around the sensor. Free air
flow ensures that the sensor is
in equilibrium with the process
temperature. At 20°C and 50%RH, 1°C
difference between the sensor and
the measurement zone will cause an
error of 3%RH. At 100%RH the error is
6%RH (see figure 2).

The Right Instrument
for High Humidity
In many applications it is advisable
to isolate the probe from the process
with a ball valve to enable the
removal of the probe for maintenance
without shutting down the process
(see figure 3).
Environments with >90%RH are
defined here as high humidity
environments. At 90%RH a
difference of 2°C can cause water to
condense on the sensor, which in an
unventilated space may take hours
to dry. Vaisala humidity sensors
will recover from condensation.
However, if the condensed water
is contaminated, the instrument
accuracy can be affected due to
deposits on the sensor, especially
salt deposits. Even the life of
the sensor may be shortened. In
applications with high humidity
where condensation can occur, a
warmed sensor head probe such as
the Vaisala HUMICAP® Humidity and
Temperature Transmitter HMT337
should be used.
The Right Instrument for
Low Humidity
Environments with <10%RH are
defined here as low humidity
environments. At low humidities, the
calibration accuracy of instruments
measuring relative humidity may not
be adequate. Instead, measuring dew
point will provide a good indication
of humidity. For example, Vaisala
DRYCAP® products are designed for
measuring dew point.
If a dryer fails in a compressed air
system, water condensation may
appear and the instrument will need
to recover. Many dew point sensors
are damaged or destroyed in such
situations, but Vaisala DRYCAP®
dew point sensors withstand high
humidity – and even water spikes.
The Right Instrument for
Extreme Temperature and
Pressure Conditions
Continuous exposure to extreme
temperatures may affect sensor
and probe materials over time. It is
therefore very important to select
a suitable product for demanding
environments. In temperatures above
When is a Sampling
System Needed for
Dew Point Measurement?
Wherever possible, the probe
should be mounted in the actual
process to achieve the most accurate
measurements and a rapid response
time. However, direct installations
are not always feasible. In such
situations, sample cells installed
in-line provide an entry point for a
suitable measurement probe.
Figure 3: A ball valve installation in a
process pipe line.
60°C the transmitter electronics
should be mounted outside the
process and only a suitable high
temperature probe should be
inserted into the high temperature
environment. Moreover, builtin temperature compensation is
required to minimize the errors
caused by large temperature
swings or operation at temperature
extremes.
When measuring humidity in
processes operating at around
ambient pressure, a small leak may
be tolerable and can be reduced by
sealing around the probe or cable.
However, when the process needs
to be isolated, or when there is a
large pressure difference between
the process and the external
environment, a sealed probe head
with appropriate mounting must be
used. Pressure leaks at the point of
entry will alter the local humidity and
result in false readings.
Note that external sampling systems
should not be used to measure
relative humidity because the
change in temperature will affect
the measurement. Sampling systems
can instead be used with dew point
probes. When measuring dew point,
sampling systems are typically used
to lower the temperature of the
process gas, to protect the probe
against particulate contamination,
or to enable easy connection and
disconnection of the instrument
without ramping down the process.
The simplest dew point sampling
setup consists of a dew point
transmitter connected to a sampling
cell. Vaisala has several models
suitable for the most common
applications and sampling needs.
For example, the easy to install
DSC74 sampling cell is designed for
the flow and pressure conditions in
compressed air applications.
In demanding process conditions,
sampling systems must be designed
carefully. As dew point is pressure
dependent, a flow meter, pressure
gauge, special non-porous tubing,
filters, and pump may be needed. As
an example, a flow chart showing the
Vaisala DRYCAP® Portable Sampling
System DSS70A for DM70 is shown in
figure 4.
9
Humidity
Installation with the ball valve set
In a pressurized system a sample
pump isn’t needed as the process
pressure induces a large enough flow
to the sampling cell.
When measuring dew point with
a sampling system, trace heating
should be used when the ambient
temperature around the cooling
coil or connecting tube is within
10°C of the dew point temperature.
This prevents condensation in the
tubing that connects the dew point
instrument to the process.
Hazardous Environments
Only products with appropriate
certification can be used in
potentially explosive areas. For
example, in Europe products must
comply with the ATEX100a directive,
which has been mandatory since
2003. Intrinsically safe products are
designed in such a manner that even
in the event of failure they do not
generate enough energy to ignite
certain classes of gas. The wiring
from the intrinsically safe product
into the safe area must be isolated
via a safety barrier. For example, the
Vaisala HMT360 series of intrinsically
safe humidity transmitters are
specially designed for use in
hazardous environments.
Vaisala HUMICAP ® Humidity and Temperature Transmitter Series HMT360 is
designed for hazardous and explosive environments.
Figure 4: The DSS70A sampling system includes a filter to clean the gas and a
needle valve to control the sample flow rate. A sample pump is needed to generate
flow from an unpressurized process gas.
Shock and Vibration
When the probe will be subject to
excessive shock or vibration, the
choice of probe, mounting method,
and installation location needs
careful consideration.
What Makes a Good Humidity Sensor?
Humidity sensor performance is a
critical contributor to the overall
quality of the humidity measurement.
Consider the importance of the
following sensor properties:
Fast Response Time
The sensor response time is the
speed of response when the sensor
is subjected to a step change in
humidity. In addition to the sensor,
factors such as temperature, airflow,
and filter type all have an effect on
response time. A blocked filter will
give a slower response.
10
Optimal Measurement
Range
The choice of humidity sensor
depends on the application and
operating temperature, especially at
the extremes of humidity.
The majority of Vaisala's humidity
sensors work over the full range
from 0 to 100%RH. Vaisala HUMICAP®
sensors are the optimal choice for
applications with a relative humidity
around 10–100%RH, whereas
DRYCAP® sensors are designed for
measurements in low humidities
around 0–10%RH.
Good Chemical Tolerance
Aggressive chemicals can damage or
contaminate sensors. The instrument
manufacturer should know the effects
of various chemicals on their sensors
and be able to give advice related to
acceptable chemical concentrations.
High Accuracy
Accuracy as a term is well
established, but difficult to define.
Each step in the calibration chain
– from the primary standard in an
internationally recognized calibration
laboratory, to the actual product
Humidity
manufacture and the measurement
on site – introduces measurement
error. The sum of these potential
errors is the uncertainty of the
measurement.
When selecting a humidity sensor,
consider the following factors
associated with accuracy:
• Linearity over the working range
• Hysteresis and repeatability
• Stability over a period of time
• Temperature dependence of the
sensor
Humidity sensors from Vaisala.
During manufacture, Vaisala
products are compared and adjusted
against factory standards that are
directly traceable to internationally
recognized standards. The
calibration chain is detailed in the
certificates that are supplied with the
majority of Vaisala products.

Protective filters for Vaisala’s humidity
instruments.
No matter what the application, the
total range of gas temperatures and
expected water vapor levels must be
known in order to decide the optimal
humidity parameters and the optimal
instrument for the environment.
The process pressure must also be
known when measuring humidity
within the process. In addition, it
must be decided whether to make the
measurement at the process pressure
or at some other pressure. For gases
other than air, the gas composition
must be known.
The terms probe, transmitter, and
sensor describe products that
measure humidity. The probe is the
part of the product that contains
the humidity sensor. The probe may
be rigidly bound to the transmitter
Vaisala designs and manufactures
a range of products for measuring
relative humidity, temperature,
and dew point based on HUMICAP®
and DRYCAP® sensors. All Vaisala
humidity instruments feature
built-in temperature compensation
to minimize the errors caused by
temperature variations and operation
at extremes of temperature. Many
of the products include built-in
calculations for other humidity
parameters.
Protect the Sensor
and Electronics with
the Right Filter
As well as screening the sensor from
any stray electromagnetic fields,
the filter protects the sensor from
dust, dirt, and mechanical stress.
A membrane or netting filter is a
good alternative for the majority of
applications. In temperatures above
80°C, in high pressure, or in rapidly
moving air up to 75 m/sec, a sintered
filter should be used.
A suitable protective enclosure
protects the instrument electronics
from dust, dirt, and excessive
humidity. An enclosure with an IP65
or NEMA 4 classification gives good
protection against dust and sprayed
water. The cable entry points need to
be sealed during installation.
When using the instrument outside,
it should be mounted in a radiation
shield or Stevenson screen to prevent
solar radiation or extremes of weather
from affecting the measurement.
Must the Instrument
Tolerate Condensation?
Making good quality humidity
measurements in near-condensing
conditions is very challenging.
Warmed probe technology ensures
reliable measurements when
measuring relative humidity close
to saturation point. The humidity
level of the warmed probe always
stays below the ambient level, where
condensation occurs.
Must the Instrument
Withstand Exposure to
Chemicals?
A chemical purge feature helps to
maintain measurement accuracy
in environments with a high
concentration of chemicals or
11
cleaning agents. The chemical purge
heats the sensor at regular intervals
to remove chemicals that may have
accumulated over time.
The Importance of
Electromagnetic
Compatibility (EMC)
There are many standards defining
the ability of products to withstand
external electrical interference.
In addition, the product must not
generate emissions that can cause
interference to sensitive equipment.
Industrial applications have more
demanding EMC requirements
than HVAC installations – the CE
marking used in Europe guarantees
compliance.
Consider Wiring
and Earthing
Except for short cable runs, a
screened cable is recommended.
Proximity to high-voltage cables or
RF sources should be avoided. It is
good practice to earth the connection
cable screen at a common point and
avoid multiple earth points. Galvanic
isolation is also available on some
Vaisala products.
Vaisala HUMICAP ® Humidity and Temperature Transmitter Series HMT330 is a
flexible product family designed for demanding industrial applications.
Which Power Supply
and Output Signals
are Needed?
The majority of measurement
instruments are powered using a low
voltage supply. If a low voltage AC
supply is used, an isolated supply is
recommended for each transmitter
to avoid earth loops or interference
from an inductive load.
Analog output instruments usually
have an option for both voltage and
current outputs. The choice depends
on the length of the signal path and
on the interfacing equipment. Some
products have a 4–20mA loop power
connection, which is a 2-wire system
where the output signal current is
measured in the supply line.
In addition to analog outputs, some
Vaisala products feature digital
communication via RS-232, RS-485,
or LAN/WLAN interfaces. Selected
commercial protocols (Modbus,
BACnet) are also available.
Consider Calibration before Purchasing
Instruments typically need to be
calibrated every year or every second
year. Calibration requirements
depend on the application and the
stability of the instrument, with wide
variations in how easy it is to carry
out field checking and calibration.
Some instruments need to be sent
to a laboratory for calibration,
for example. Understanding the
calibration needs is therefore
an important part of instrument
selection.
Calibration Frequency
An individual calibration certificate
for a particular instrument indicates
the accuracy and linearity at the time
12
of calibration. However, it does not
reflect the stability of the instrument
in the long run. Calibration at routine
intervals is essential to understand
the instrument’s long-term stability.
Calibration frequency depends on
the operating environment. A rule
of thumb for Vaisala instruments
is that yearly calibration is enough
for HUMICAP® products, whereas
in most applications a two-year
calibration interval is suitable for
DRYCAP® products. When measuring
in constant high humidity (>85%RH),
high temperature (>120°C), or
chemically aggressive atmospheres,
more frequent checks may be
needed.

Humidity Instrument
Calibration
In calibration, the humidity reading
of an instrument is compared against
a portable reference. The reference
should be regularly calibrated and
provided with a valid certificate.
When selecting one of the many
calibration methods, time, cost,
technical requirements, expertise,
and the unique needs of the
organization must be balanced.
Portable meters and products that
can be removed from the installation
can be calibrated in an approved
laboratory or returned to the
instrument provider for calibration.
Vaisala has four Service Centers
around the world available for
calibration.
Instruments installed in processes
that operate within narrow
boundaries can be calibrated using
on-site one-point calibration that can
be performed without disconnecting
the instrument. One-point calibration
can also be used to identify the
need for further calibration and
adjustment.

HUMICAP® Hand-Held Humidity

the Vaisala DRYCAP® Hand-Held
Dewpoint Meter DM70 can be directly
connected to the installed product
and the readings compared to those

variations in humidity, multi-point
calibration is recommended. Twopoint or three-point calibrations

can be accomplished in the
field with the help of humiditygenerating equipment, as long as

HMT330 Series Humidity and Temperature
Transmitters for Demanding Humidity Measurement
Features/Benefits
The HMT330 transmitter family offers reliable performance for a wide variety of
demanding industrial humidity measurements.
The Vaisala HUMICAP® Humidity
and Temperature Transmitter Series
HMT330 is designed for demanding
industrial applications where
stable measurements and extensive
customization are essential. With
multiple options to choose from, the
instrument can be tailored to meet
the specific needs of each individual
application.
Proven Vaisala HUMICAP®
Performance
The HMT330 series incorporates
Vaisala’s 40 years of experience in
industrial humidity measurement.
The updated fourth-generation
HUMICAP sensor provides accurate
14
and stable measurement even in
environments with high humidity or
chemical contaminants.
Chemical Purge Minimizes
Effects of Contaminants
In environments with high
concentrations of chemicals and
cleaning agents, the chemical
purge option helps to maintain
measurement accuracy between
calibration intervals.
The chemical purge involves heating
the sensor to remove harmful
chemicals. The function can be
initiated manually or programmed to
occur at set intervals.

to generate over four years of
measurement history, and zoom in on
any desired time or time frame.
The display alarm allows any
measured parameter to be tracked,
with freely configurable low and
high limits.
Versatile Outputs and
Data Collection
The HMT330 can support up to three
analog outputs; an isolated galvanic
power supply and relay outputs are
also available.
For serial interface the USB
connection, RS232, and RS485 can
be used.
HMT330 is also capable of applying
the MODBUS communication protocol
and, together with an appropriate
connection option, provides either
MODBUS RTU (RS485) or MODBUS
TCP/IP (Ethernet) communication.
The data logger, with real-time clock
and battery backup, guarantees
reliable logging of measurement data
for over four years. The recorded
The display shows measurement
trends and over four years of real-time

data can be viewed on the local
display or transferred to a PC with
Microsoft Windows® software. The
transmitter can also be connected to
a network with an optional (W)LAN
interface, which enables a (wireless)
Ethernet connection. A USB service
cable makes it easy to connect the
HMT330 to a PC via the service port.
Flexible Calibration
The HMT330 instruments are
calibrated at six humidity points
at the factory and come with a
calibration certificate that meets
all the relevant traceability and
compliance requirements.
A quick, one-point field calibration
can be performed with the handheld HM70 meter. A two-point field
calibration can be performed,
for example, with the HMK15 salt
bath calibrator in a controlled
environment. The transmitter
can also be sent to Vaisala for
recalibration, and accredited
calibrations are available.

• With a warmed probe, for near-condensing conditions
and dew point measurement
• With a warmed probe and an additional temperature
sensor, for near-condensing conditions and relative
humidity measurement
True Humidity Readings in Condensation
Conditions
Vaisala’s unique warmed probe provides fast and reliable
measurement in environments where humidity is near
saturation. The heating prevents condensation from
forming on the sensor.
As the probe is heated, the humidity level inside it stays
below the ambient level. With accurate temperature
measurement, the ambient dew point can be calculated
precisely.
If the relative humidity value is needed, an additional
temperature sensor is used. The measured ambient
temperature provides the compensation for calculating
relative humidity and other humidity parameters.
Installation Options
Tight installation through a process wall can be achieved
with Swagelok ® fittings. The optional HMT330MIK
Installation Kit is available for outdoor installations; duct
installation kits are also available.

Transmitters for High Performance HVAC Applications
Features/Benefits
The HMW90 Series Humidity and Temperature Transmitters are designed for
demanding HVAC applications.
Wall-mounted Vaisala HMW90
Series HUMICAP® Humidity and
Temperature Transmitters measure
relative humidity and temperature
in indoor HVAC applications, where
high accuracy, stability, and reliable
operation are required.
The flexible HMW90 series offers
a variety of options and features.
Transmitters include a display and a
sliding cover with either an opening
for the display or a solid front. Both
analog and digital output options,
including special scalings and
calculated parameters, are available.
Quick and Easy to Install
HMW90 series transmitters are quick
and easy to install. The wiring is
connected through the back plate
and the electronics with the sensors
can be snapped on easily after the
wiring is complete. The transmitter is
configured using dip switches, which
are accessible when the enclosure
is open.
38
Digital Communication
Brings Benefits
The introduction of digital (BACnet/
Modbus) communication to field level
devices brings many advantages. For
example, all sensors can be centrally
accessed and their performance
can be easily monitored. Wiring is
simple when multiple sensors are
installed on the same bus. Sensors
can be set up using standardized
tools, and the system can be enlarged
with additional sensors quickly and
conveniently. In addition, parameters
influencing measurements, such as
pressure or site elevation, can be
centrally set and updated.
Choose from a Wide
Variety of Calibration
Options
On-site calibration and adjustment is
exceptionally easy. The sliding cover
exposes offset trimmers for onepoint calibration without disturbing
measurement. The display instantly
indicates the effects of changes,

these products the ideal choice for
demanding applications.
Measures both Humidity
and Temperature
Resistant to Chemicals
and Dust
The accuracy of the transmitters
is simple to check using either
the Vaisala HUMICAP® Hand-Held
Humidity and Temperature Meter
HM70 or the Vaisala HUMICAP®
Humidity Indicator HMI41. The
calibration can be done in seconds
with a single potentiometer without
disturbing the operation, resulting
in great savings both in maintenance
time and costs.
The duct mount HMD60 and HMD70
transmitters can also be used in
many industrial humidity monitoring
applications, where their stability
and resistance to chemicals and dust
are of great value. A useful feature
of these duct mount transmitters is
the ability to remove the electronics
without removing the unit from

The Vaisala HUMICAP® Hand-Held
Humidity and Temperature Meter
HM70 is designed for demanding
humidity measurements in spotchecking applications. It is also ideal
for field checking and calibration of
Vaisala's fixed humidity instruments.
The HM70 incorporates the latest
generation of the Vaisala HUMICAP®
Sensor. It is reliable and has better
than ever long-term stability.
Additionally, it has a sensor that
copes well with chemical interference
and provides accuracy that lasts in
demanding conditions.
The chemical purge option
maintains measurement accuracy
in environments with high
concentrations of chemicals. The
sensor preheat option reduces
measurement delays as it keeps
the sensor dry when the probe
is inserted into hot and humid
processes.
Three Probes
to Choose from
The HMP75 is a general purpose
probe whereas the HMP76 is a long,
stainless steel probe especially
suitable for spot-checking in ducts.
The HMP77 is a small probe at the
end of a 5-meter cable. The probe is
ideal for difficult-to-reach areas and
for on-site calibration of Vaisala's
process transmitters.
In addition, the HM70 supports the
use of Vaisala's dew point, carbon
dioxide and moisture in oil probes,
allowing measurements in several
multiparameter applications.
MI70 Link
The optional MI70 Link Windows®
software and the USB connection
cable form a practical tool for
transferring logged data and real
time measurement data from the
HM70 to a PC.

Humidity and Temperature
Probe HMP42
The HMP42 probe can be used for spot
checking humidity and temperature
in applications which require an
extremely thin probe. Typically the
probe is used for monitoring the drying
of structures during construction or
after water damage. It is ideal to be
used when measuring in any tight
places, in ducts or chambers or, for
example, under a linoleum floor.
The probe diameter is only 4 mm,
allowing access into very small, tight,
and hard-to-reach spaces.

Typical applications for the HMP46
are plant maintenance, installation
and inspection of air conditioning
systems, production and storage areas
and production processes. The HMP46
operates in full humidity range of
0 ... 100 %RH. The temperature range
is from -40 to +100 °C (-40 ... +212 °F).
For short periods of time, the probe
can withstand temperatures up to
+180 °C (+356 °F).
The HMP46 probe is solid and
rugged. Its stainless steel probe is
made to withstand rough handling in
mechanically demanding applications.
The probe’s long shaft can also reach
otherwise unreachable places.

SHM40 Structural Humidity Measurement Kit
A borehole in concrete and a measurement
probe HMP40S inserted in it.
Vaisala HUMICAP ® Structural Humidity Measurement Kit SHM40 offers an easy and
reliable solution for humidity measurements in concrete and other structures.
Concrete dries unevenly and is usually
drier on the surface, consequently
it is important to measure beneath
the surface conditions. The borehole
method provides information about the
humidity profile under the surface. In
this method, a humidity probe is left in
the borehole until the humidity in the
hole has reached an equilibrium state
and the stabilized values can be read.
SHM40 Is All You Need
for Borehole Humidity
Measurement
The Vaisala HUMICAP ® Structural
Humidity Measurement Kit SHM40
is an ideal solution for the borehole
method. The starter kit is comprised of
an HMP40S probe, HM40 indicator and
accessories for the borehole method in
a weather-proof case, optimized for use
in harsh and humid construction sites.
Additional accessories for the SHM40
can be used to prepare a moisture
measurement hole in fresh concrete.
Pre-formed holes eliminate the need
for drilling and the risk of damaging
70
heating elements or tubing embedded
in the concrete.
Easy Measurement with
Multiple HMP40S Probes
and Quick Connectors
HMP40S measurement probes
are interchangeable. The probes
connect easily to the HM40 indicator
with a snap-on connector enabling
convenient use of multiple probes
with one indicator. The measurement
data can be displayed in numeric,
statistic or graph views.

challenging in environments
where humidity is near saturation.
Measurements may be corrupted
by fog, mist, rain, and heavy dew. A
wet probe may not give an accurate
measurement in the ambient air.
74
This is an environment to which
Vaisala has designed a patented,
warmed probe for reliable measuring.
As the sensor head is warmed
continuously, the humidity level
inside it stays below the ambient
level. Thus, it also reduces the risk of
condensation forming on the probe.
Fast Measurements
With its fast response time, the
additional temperature probe for the
HMP155 is ideal for measurement
in environments with changing
temperatures. The new membrane
filter speeds up the RH measurement.

Long Lifetime
Protecting the sensor from scattered
and direct solar radiation, and
precipitation will increase its lifetime.
Thus, Vaisala recommends installing
the HMP155 in one of the following
radiation shields: DTR503, DTR13,
or a Stevenson screen. For the
additional temperature probe, an
installation kit is available to be
used with DTR502 radiation shield.
Easy Maintenance
The probe can be calibrated using a
pc with a USB cable, with the push
buttons, or with the MI70 indicator.

The Vaisala Meteorological
Installation Kit HMT330MIK enables
the Vaisala HUMICAP® Humidity
and Temperature Transmitter
HMT337 to be installed outdoors to
obtain reliable measurements for
meteorological purposes.
True Humidity Readings in
Condensing Conditions
In weather observations dew
formation makes reliable humidity
measurement difficult. When dew has
formed on the humidity sensor, it is
impossible to obtain a true reading
until this dew evaporates.
Both the PTU307 and HMT337 avoid
this problem by warming the probe.
When warmed, the relative humidity
inside the probe stays below the
ambient level. With an accurate
temperature measurement, the
ambient dew point can be calculated
precisely. To obtain the ambient
relative humidity, an additional probe
measures the ambient temperature,
Open Shield Prevents
Microclimates
The warmed probe of the HMT337/
PTU307 is mounted in a shield which
is open at the bottom to ensure steady
air circulation to the sensor even in
calm weather.
In traditional radiation shields sleet
or snow can accumulate on the shield
and prevent the proper air circulation
through the shield, and create a humid
microclimate until the snow melts.
Essential for Critical
Weather Measurements
Obtaining a true humidity reading is
particularly important e.g. in traffic
safety: at airports and at sea as well
as on the roads. It is essential, for
example, in fog and frost prediction.
For calibration, a portable HMP77
reference probe is easy to attach beside
the HMT337 or PTU307 probe.

cause errors in measurement. The
patented warmed probe prevents
condensation from forming on the
sensor.
Protective Enclosure
The HMT300TMK includes a white,
painted stainless steel enclosure
with an installation kit for the
probe. The HMT337 Humidity and
Temperature Transmitter is installed
in the stainless steel enclosure at the

Outer cover provides
protection from rain and
direct sunlight
It is ideal for measuring in water
vapor injection applications because
the sensor has been optimized for
high humidity environments by
utilizing a patented, warmed probe.
Water vapor is added to the intake of
the turbine to increase the mass flow
which in turn increases compression
and electrical power output.
Low Maintenance
Power turbines also require exact
water vapor injection in the chamber
to reduce pollutant emissions.
Vaisala’s warmed probe technology
is ideal because of its reliability in
the field. In fact, the only suggested
scheduled maintenance is annual
calibration.
Patented, Warmed Probe
Prevents Condensation
The HMT300TMK with the HMT337
installed, provides fast and reliable
dewpoint measurement especially
under high humidity conditions
where dew would normally form
The outer cover protects the
transmitter from direct sun light and
rain. The installation kit protects the
probe from outer water splashes,
keeps the sensor dry, and prevents
any parts that could vibrate loose
from entering the turbine.
The HMT300TMK can be ordered
separately for installation with the
customer’s existing HMT337.
HUMICAP® Performance
The HMT330 Series Transmitters are
fitted with the latest generation of
the HUMICAP®, the polymer sensor
known for its accuracy, reliability and
long-term stability. The sensor has a
high tolerance for particulate abrasion
and chemical contamination.
Vaisala HUMICAP®
Humidity and Temperature
Transmitter HMT337
The HMT337 is intended for
