general

The microvoltmeter has a sturdy plastic case with a carrying handle which can be adjusted in 30° steps. Controls and indicators are located in a clear, logical configuration. Controls are grouped in accordance with the various functions of the unit.

German Cathodic Protection

Measuring range

The microvoltmeter is a highly accurate moving coil instrument equipped both with an accumulator and a 230 V, 50-60 Hz socket for direct line connection. Two scales are provided with

10 skt and 3 skt. Fullscale ranges from 10 µV to 300 V

polarity indicator and Zero adjustment

The unit features automatic polarity switching to ensure correct readings irrespective of polarity. Two LED´s on the front panel indicate the polarity of the voltage measured; a control is provided for zero adjustment on the µV-range.

Technical Data

Measuring range input impedance

Active Filters for eliminating AC-influence

The 16 Hz and 50 Hz low-pass filters can be used to eliminate interference frequencies during measurements.

Display accuracy

Drift

Isolated Amplifier Output

An output socket for the connection of an external recorder to document the measurements is located in the front panel. A special isolating amplifier is connected to the socket to isolate it from the input circuit. Recorders with earthed inputs can therefore be used without distoring the measurement.

power supply 230 V

Power supply either via the 220 V socket or via the built-in

NiCd batteries is possible. The unit is equipped with a built-in battery charger, an automatic monitoring system and protection against excessive discharging. Both battery charging and battery charge conditions are indicated.

LC-4 Handheld multimeter

Document No.: 11-102-R0

Sheet: 1 of 1

LC-4 Handheld Multimeter

German Cathodic Protection

Pick up a Model LC-4 and have these features in the palm of your hand

DC volts for IR drop, potential & rectifier readings

AC volts for potential & rectifier readings

Ohms for continuity & resistance testing

Selectable input resistance display „freeze“ for instant off & coordinated tests

Optional plug-in shunt for current readings

Heavy duty carrying case

general

Model LC-4 is a hand-held voltmeter to include a number of special

features which facilitate corrosion and cathodic protection testing on underground structures. It is designed for field testing under almost any environmental conditions. Sealed Mil Spec. switches, sealed windows, a gasketed case and a printed circuit board with baked-on moisture and fungus resistant coating on both sides make this possible.

The large (0.5“) display characters are easy to read under both high and low lighting conditions and function over a wide temperature range with very little drain on the battery.

The LC-4 is recommended for potential surveys, side drain measurements, surface potential surveys, IR drop measurements, checking both the AC and DC circuits of rectifiers, checking for stray or hazardous AC potentials, and checking galvanic anodes. DC current measurements require the use of an optional plug-in shunt (0-20 Amp).

The selectable input resistance feature permits detection of high resistance in the external circuit and elimination of resulting errors in virtually all cases.

The push-to-hold-reading button freezes the display at any desired time, which makes the meter usable in many areas having varying stray currents. It is also useful when conducting instant-off and coordinated tests.

accessories spare Carrying Case

Made of heavy, water resistant simulated leather, this carrying case leaves your hands free to perform tests.

A quick opening snap permits ready access to the instrument, and a belt loop is included with a snap fastener.

electrode extension adapter

Designed to save effort (and your back) as well as to protect you from snakes and poison ivy, the MCM electrode extension adapter firmly mates with the base of the meter by the use of Velcro® pads. The base has a threaded socket which connects to either input terminal by means of a test lead pigtail with a banana plug. Any

MCM intermediate electrode extension can be screwed into the socket.

Measuring equipMent earth resistance and resistivity tester

Mru-105

Document No.: 11-302-R1

Sheet: 1 of 1

general information

The MRU-105 is a portable meter for measuring earth resistance and resistivity (Wenner’s method). The instrument can measure resistance with a 2, 3, or 4 poles method. The very high immunity for existing interference voltage AC + DC at which measurement is still performed:

24V (68V-p-p) but also measurement of existing interference voltage up to 40V is unique functionality of meters. Moreover meters measure the resistance of the probes and calculate automatically the error coming from probe`s resistances. The meter additionaly can be powered from

Ni-MH batteries or standard C size, and the test results can be stored in the internal memory and transmitted to PC via USB-cable. Measurements can be simplified using current clamps.

SPECIFIC SOIL RESISTIVITY ( p )

p = r x f = 2.5 x 10 cm

p = 25 cm

The soil box can be used for the measurement of specific resistivity of electrolytes ie. soil sample, water and conducting fluids.

The specific resistivity is measured by using a normal

4 -terminal earth resistance meter in accordance with

Wenner´s 4 - electrode method.

The soil box consists of a plastic container with metal end plates for passing current through the soil sample packed into the box and potential terminals permitting measurement of voltage drop across a section of the soil sample,

The dimensions of the box and position of electrodes are designed so that resistivity of electrolyte sample in the box is obtained by multiplying the resistance value in Ohm indicated by the meter by the form factor (printed on box).

The test sample should be filled up to the top of the box.

The soil samples should be carefully filled and compacted to ensure proper contact with the plates and rod electrodes and also to remove air bubbles and voids.

The test box method gives very accurate results for fluids but the value measured for soil samples may differ from those measured at actual site due to variations of natural conditions including moisture, compaction, void ratio, particle size etc..

- geo-electrical imaging system

The SuperSting™ with Wi-Fi

®

is a portable resistivity, induced polarization (IP), and self-potential (SP) instrument with memory storage and user-defined measure cycles. It provides the highest accuracy and lowest noise levels in the industry. The instrument comes in two versions: the single-channel version R1 and the eight-channel version R8.

The R8 measures up to 8 channels simultaneously for each current injection, making it up to 8 times faster than the

R1 model. Both models exhibit the accuracy, reliability and ruggedness that all Advanced Geosciences instruments are known for.

The instrument uses a built-in power transmitter and can be used for traditional vertical electrical sounding (VES), mise-a-la-masse measurements, or multi-electrode electrical tomography in 2D, 3D and 4D (time lapse). Other applications include borehole-to-borehole tomography and underwater measurements in rivers, lakes, dams and the sea to investigate bottom conditions.

geo-electrical imaging with android™ app & Wi-Fi

Key Features of the supersting™ Manager app

You have all important information about each data point immediately available by touch screen.

The electrodes for each data point are highlighted in case a survey needs to be paused and restarted to fix a loose electrode and thus save important time in the field while improving data quality.

A floating window displays apparent resistivity, voltageRx/currentTx, voltageRx, currentTx, voltageTx, power, % error, command line number and the channels used.

The contact resistance data is now saved in a separate file documenting this primary data quality control condition along the line.

What if my android™ device gets lost or runs out of power?

Your data is safe because it is saved both on the SuperSting™ instrument and on the Android™ device.

The survey will continue localy on the SuperSting™ and can be fully controlled from the standard

SuperSting™ keypad.

What happens if i get out of Wi-Fi® range?

The Wi-Fi® max range is 100 meter depending on terrain, atmosphere etc. The SuperSting™ will continue to measure even if the Android™ device gets outside the range. As soon as the device returns within range the SuperSting™ App reconnects and continues all functions as before without losing any data.

The earthimager 2D is used to interpret 2D resistivity profiles created with any electrode array, recorded with electrodes in one plane, i.e. on a line on the surface, between two or more parallell bore holes, or between bore hole and surface. Any array or mixed data from Schlumberger, pole-pole, pole-dipole, dipole-dipole or Wenner electrode arrays are possible to invert. A special „Survey Planner“ allows the user to enter a geological model and run a virutal survey and then invert the virtual data to see if the objective of the survey can be met.

the 2D time lapse module, is used when information about resistivity changes in the ground is needed. Some common situations include potential leakage from landfills, industrial sites, etc. Other monitoring situations include fracture tracing by injection of a conductive solution such as a salt solution. Other possible monitoring situations include saltwater intrusion in coastal areas, remediation progress at environmental sites, groundwater recharge, infiltration studies, to see how the ground is

earthimager 3D will automatically determine a three dimensional resistivity model for the subsurface using the data obtained from a 3D electrical imaging survey with the electrodes arranged in boreholes and/or on the surface and presents a 3D volume of inverted resistivity data with advanced volume rendering technique. The final resistivity or IP image-volume can be rotated in any orientation, zoomed in and out, and translated to anywhere inside the image window in order to see the volume of interest in detail. Colors representing areas of less interest can be made transparent so that the shape of a pollution plume, for example, can be visible. With EarthImager 3D, resistivity inversion can be as easy as two steps: Read Data and Start Inversion with only a few mouse clicks.

supersting swift Dual Mode (us patent 6,404,203) electrode switches

The Swift dual mode electrode switches facilitate automatic induced polarization measurement in a multi-electrode array using stainless steel stakes for current injection and non-polarizable (porous pot) electrodes for the potential measurements. The electrode switch can operate either as a dual mode electrode with separate current injection and potential measurement or in mono mode where both current injection and potential measurement occurs through the stainless steel stake. The electrode switches have been re-designed in order to reduce the size of the electrode switch. On one side of the electrode switch is a miniature banana jack where the non-polarizable electrode is connected when the electrode is used in dual mode. When the banana jack is not in use, it is covered by a plug to prevent dirt and moisture to enter the jack.

earthimager 2D

AGI EarthImager 2D is a Windows based computer program that interprets two-dimensional (2D) electrical resistivity and induced polarization (IP) data and produces inverted resistivity and IP sections that reveal the sought-after target and subsurface geology. EarthImager turns the complicated resistivity data inversion into a simple step wise process, i.e., reading a data file, running the inversion and plotting the figurs for a report. EarthImager also presents a long list of options for advanced users.

EarthImager supports all Windows true type fonts and Windows 24-bit true color. Hardware accelerated graphics powered by OpenGL leads to fast graphics on the screen and export of report ready plots. The graphical user interface allows browsing of the processing results from one parameter to another and one iteration to another. There are multiple visualization options such as 3D volumes with variable opacity and color scale so that the viewer can see inside a subsurface volume.

general

The new MiniLog2 is a waterproofed universal measuring instrument with

LCD and keyboard designed for CP measurement tasks. Used in data logger mode, the MiniLog2 samples for both channels DC and AC simultaneously.

In interrupter mode, the built-in relay swiches fully GPS synchronized for interrupting not only rectifiers, but coupons for IR-free potentials. Finally with survey mode, the MiniLog2 is able to make DCVG and CIPS surveys while storing the GPS position for every measuring point taken.

Datalogger with Microvolt

Measurement

Two channel sampling, each with DC and

AC measurement, resulting in 4 values simultaneous measured per sample.

Both DC channels got microvolt resolution and have active filters built-in to prevent low AC frequency interference. The MiniLog2 is able to sample up to 1 300 000 values.

This results in up to 20 min. sampling even when measuring in “High-Speed mode” (= 1,000 measurements / second). The built-in USB connector allows galvanically isolated data transfer via a USB.

Miniaturised gps interrupter with rechargeable Battery

The MiniLog2 has a mechanical

15A/60V relay built-in for switching of rectifiers, flanges and coupons.

Optionally a version with built-in electronic relay 30A/60V is available.

Via the keyboard and the LCD a switching cycle resolution of

0.1s is configurable by the user. In addition, night and weekend savings are selectable. The rechargeable Li-Ion battery allows

GPS synchronised switching for 30 days without recharging.

For fixed installations in rectifier housings an USB mains supply and fix mount can be used. To increase the switching power even more, miniaturised external slave relays for

MiniLog2 are available with 50 A and 100 A.

Coupon Measurement with

MiniCoup

For measuring IR-free potentials on a coupon, MiniLog2 can sample and interrupt simultaneously.

For accurate sampling of the complete off depolarisation curve,

MiniLog2 is able to measure 1000 samples/s for one channel for up to 20 min. time.

Optionally with the „MiniCoup“ adapter and its built-in 10

Ohm shunt, the MiniLog2 samples every second for up to 24h. By just connecting pipe, electrode and coupon with the adapter sockets, On and Off potential and DC and AC current are collected simultaneously.

gps synchronisation and gps position

The optional Garmin GPS receiver allows synchronisation of the MiniLog2 time and date. Using the MiniLog2 as data logger in DCVG survey mode, the GPS positions are automatically stored beside each value.

DCVg and Cips survey with google

Maps presentation

Like with an analogue multimeter,

MiniLog2 shows the DCVG voltage difference in a bar graph for quick recognition. With a simple press of the „OK“-button mounted on the electrode, the DCVG value and the related GPS position are stored and the survey continues. In the same way potential (CIPS) and/ or voltage gradient measurements can be done.

The survey path and the defects can be directly presented with

Google Maps and the WinLog 2.0 software.

Current interrupter - GPS-Syntakt

Document No.: 11-501-R1

Sheet: 1 of 2

Current Interrupter - GPS-Syntakt -

General Information

The GPS-Syntakt time switch is used for the synchronous switching of rectifiers, flanges and coupons for cathodic corrosion protection applications.

After having been synchronised, the switching cycle (4/2, 12/3 or 27/3) is maintained even when the device is not in operation and immediately available again even after the time switch has been transported in an instrument car for several weeks.

GPS-Synchronisation

GPS-Syntakt resynchronises itself automatically every 2 hours via the connected GPS antenna and thereby guarantees continuous synchronous switching without time deviations. The GPS reception quality and successful GPS synchronisation (during the last 24 h) are indicated by a two-colour LED on the front panel.

Manual and External Synchronisation

It is possible to manually synchronise via the corresponding push button or externally via another timer when no GPS antenna is connected. In this respect the functions correspond to the functions of the predecessor

Syntakt.

High-Precision Quartz Time Base

Being equipped with a highly precise and temperaturestabilised quartz time base the GPS-Syntakt enables synchronous switching for several weeks without resynchronisation.

Battery Operation

During GPS-operation

GPS-Syntakt’s internal lead-acid storage battery facilitates mains-independent synchronous switching for more than 6 weeks.

During 230 V mains operation the internal storage battery is automatically charged, and the installed charging electronics monitor the charge state.

LS50 - Electronic Powerswitch 50 ampere

German Cathodic Protection

Night and Weekend Shutdown

It is possible to suspend the switching operation during the night and on weekends via a programmable LCD clock display installed on the front panel in order to maximise the protective current for the pipeline.

Secondary Switching

Power:

Mechanic Option:

60 Volt DC / 15 A (via pole terminals)

Electronic Option:

100 Volt DC / 30 A (via pole terminals)

Connection of External Slave Relays

To increase the switching power, an external slave relay can be additionally connected when the time switch is 230 V mains-operated.

The LS50 slave relay permits switching power rates of up to 50 A

.

The LS100 slave relay permits switching power rates of up to 100 A

.

LS100 - Electronic Powerswitch 100 ampere

Powerswitch with electronic relay. Build for usage in combination with a switcher.

The LS50 is intended for switching of CP rectifiers, flanges, soutirages and drainages.

GPS Synchronisation

Set the < Cycle> switch to the desired switching cycle (e.g. 12/3)

Set the < Mode> switch to [1 Normal] or for an operation including night and weekend shutdown to [2 Timer]

Insert the bullet connector of the GPS antenna in the [ Signal GPS] socket of GPS-Syntakt.

Align the GPS antenna as horizontally as possible with an unobstructed view of the sky. It is possible to position the antenna horizontally below a plastic main cover inside a rectifier cabinet. A GPS reception in metal cabinets, buildings or in forests underneath dense vegetation is mostly impossible.

In general, only one successful GPS reception within 24 h is necessary due to the highly precise and temperature-stabilised quartz time base of GPS-Syntakt.

During mains operation GPS reception attempts are performed continuously. During battery operation GPS reception attempts are only made every 2 h to spare the storage battery. However, by pressing the < Battery Mode> push button twice (on and off) it is possible to manually start a new GPS reception attempt at any time during battery operation.

The ( Signal GPS) LED indicates a sufficient GPS signal by flashing in Green colour. It is flashing in Red colour when the signal is insufficient.

A Green (GPS SYNC) LED signalises at least one successful GPS synchronisation during the last 24 h. A Red LED indicates that there has not been any GPS synchronisation during the last 24 h.

The ( GPS SYNC) LED is flashing during battery operation to keep the current consumption low. It is continuously illuminated during

230 V mains operation.

German Cathodic Protection

porosity detection and corrosion control

Flaws in protective coatings such as pores, cracks and fissures, if undetected, may impair the corrosion resistance of a product.

The PoroTest 7 has been specifically designed for nondestructive porosity testing of such coatings, based on automatic test voltage control specific to the thickness of material to be tested and vice versa. The major fields of application of the

PoroTest 7 range from vendor inspection to quality assurance in corrosion protection.

Test principle and field of application

Designed for detecting flaws and pores, the PoroTest 7 can be used for testing all insulating coatings on conductive substrates such as steel, Aluminium, etc.

The test instrument consists of a high voltage probe with an integrated high voltage generator and a test electrode, which is simply connected to the probe. The control unit features a digital display and control pad. The control unit housing is fully portable and made of rugged ABS plastic with an integrated handle. The high voltage probe and control unit are connected via a rugged cable. To detect porosity, the appropriate test voltage specific to the material thickness is set on the control unit which applies, when activated, a spark discharge at the moment a material flaw is detected.

In addition to the spark discharge, flaws are indicated by a visible and audible signal and counted. Typical applications: Testing linings and coatings applied on ducts, pipes, hulls, oil and storage tanks, enamel, paint, rubber and bitumen linings, vessels and tanks, GFK and other plastics materials.

ISOTEST 4S - Porosity Testing of Coatings

German Cathodic Protection

Application

ISOTEST 4S is indispensable in the area of passive corrosion protection.

Non-destructive high voltage testing of the most diverse coatings and corrosion protection materials has proved itself again and again over long periods of time. The test, prescribed by many works’ specifications and Standards, has made a successful contribution, within the framework of quality control to reducing stoppalte times and avoiding interruptions to production and subsequent repair costs.

Coating thicknesses from a few hundred micrometres to several millimetres can be tested for pores, cracks or scarcely discernible transport damage by means of short high voltage impulses. The short action time of the impulses, which treats the material gently, makes it possible to test with reserves of energy, which, in turn, guarantees the stability of the selected test voltage even with dirty or damp surfaces.

ISOTEST 4S stands for:

Robust construction for using at construction sites

Testing of dyrty, damp and even slightly conductive surfaces

Defective areas can be clearly distinguished, whether it be with externally or internally coated tubes, rubber coated containers, seams in plastic, fully coated fittings or machine parts

... everywhere where non conductive coatings are overlaid an conductive materials (e.g. metal, wet concrete) or where non conductive coatings have an underlay of conductive materials (e.g. plastic seams in tubing or containers).

The pH value describes the activity of hydrogen ions in aqueous solutions on a scale of -1 to 15. Based on this scale, liquids are characterised as being acidic, alkaline or neutral: a solution which is neither acidic or alkaline is neutral. This corresponds to a value of 7 on the scale.

Acidity indicates a higher activity of hydrogen ions and a pH value lower than 7. Alkaline solutions are characterised by a lower hydrogen ion activity or higher hydroxide ion activity, respectively and a pH value above 7. The graph below uses examples to illustrate the pH scale.

The pH scale is logarithmic. A difference of one pH unit represents a tenfold, or ten times increase or reduction of hydrogen ion activity in the solution. This explains how a solution’s aggressiveness increases with the distance from the neutral point.

The pH value can be measured using electrochemical measuring systems, litmus paper, indicators and colorimeters. Of these methods, electrochemical sensors provide the most accurate results.

The pH electrode is an electrochemical sensor which consists of a measuring electrode and a reference electrode. The measuring electrode is made of special glass which, due to its surface properties, is particularly sensitive to hydrogen ions. It is filled with a buffer solution which has a pH value of 7.

The monitoring and control schemes of cathodic protection systems require very accurate measurement of relatively very low potential differences between metallic objects and surrounding electrolytes soil or water, with respect to a standard reference electrode :

Zn, Cu/CuSO

4

, ag/agCl or MnO

The conventional low input impedance instrument can not be relied upon to give good results in such cases. The zinc reference electrodes which have relatively longer reliable operation life than other electrodes are installed in permanent systems but the measured values are to be usually / conventionally displayed and reported in terms of potentials with respect to Cu/CuSO

4

or Ag/AgCl reference electrodes for easy interpretation of results.

German Cathodic Protection

The present practice of marking the scales for both types of reference electrodes on analog type instruments solves the problem to some extent but not at all when the low input impedance analog type instruments are replaced by high input impedance digital instruments.

The transmission of field data by long cables between local measuring points and master control station for remote monitoring and controls, makes it necessary to convert the measured low voltage signal into an equivalent low current signal to preserve its integrity. These practical considerations indicated the need of developing a potential converter which can be conveniently connected across the conventional potential measuring devices to provide the desired results.

portable reference electrodes

German Cathodic Protection

Portable reference electrodes are used to carry out potential measurements on all types of buried and submerged structures. The reference electrodes are made of solid copper elements which are housed in impact resistant plastic tubes.

To ensure that the copper elements remain electrically stable, copper sulfate crystals are provided with each ordered reference electrodes. The crystals surround the copper elements in the plastic tube, and when mixed with distilled water, create a super saturated solution of copper sulfate to reduce ion intermixing. A window on each cell allows the operator to observe the water level of the crystallized solution. If the level is insufficient, water and copper sulfate crystals can be simply added by removing the filling cap found on each creference electrodes.
