The PGU 10V-100mA is a laboratory potentiostat / galvanostat for the measurement of lowest currents. The modulation voltage amounts to approximately ±13V, the polarization voltage ±3V with the integrated nominal voltage generators and ±10V with interface. The maximal measureable current amounts to 100mA that is enough for many tasks. The lowest current range is 100pA that is equivalent to a resolution of 10fA=1mV. A feature is the battery operation. If the device is used without interface or with an external one then the potentiostat will be able to work extremely noiseless and potential-free in battery operation for several hours.
The PGU 10V-1A is a cheap laboratory device. As solid constructed potentiostat / galvanostat it performs a variety of standard experiments.

The PGU 100-PCR is our potentiostat / galvanostat for standard measurements and for the measurement of the electrochemical noise. The basic construction is equivalent to the PGU 10V-100mA. Two more modules on the right side of the device extend the features for the measurement of the electrochemical potential and current noise. These modules provide several special features like AC-interlinking, switchable filter frequencies and amplification. Meanwhile we have also equipped other devices of the PGU-series with these noise modules with the result that the measurement of the electrochemical noise is not limited anymore to this type of device.
The devices of the PGU-MOD Series are built for pure computer operation. They contain neither display modules nor manual control elements. The design is considerably smaller than other standard PGU devices. The picture above shows a single device, the following picture a four-channel device. With a current range
of 100nA to 200mA or 100mA to 10nA, most applications are processed. Interface and our software EcmWin are included in the product contents.
When multiple channel devices are connected to a computer, EcmWIn is started several times, so that each module can be operated separately and with full range of functions.
The PGU-MOD-TP device is a extension of the PGU-MOD. It is designed with a touch panel for operation and display. It is conceived for stand alone operation. The potentiostat can be loaded with a configuration software with various polarization functions. These functions are associated to function keys and can be started with a "keystroke" on the touch panel. The storage of the measurement data is ensued on a USB stick. The data can be accessed via ethernet network or by changing the stick. Futhermore specific customized analyze modules can be deposited that allows an evaluation of the results by skilled persons (quality management).
The PGU-1A-OEM is a more powerful model of the PGU-MOD-series. With a maximum current of ±1A measurement tasks that require a higher current can be processed.
It is built in a 42HP case, compared to the 100/200mA variant with its 28HP case. If additional potentiostats shall be accommodated in the same housing, we use a twice as high (6U) standard 84HP wide table top case. The following picture shows the 2A version.
Especially at request of a customer, we equipped the 2A model with additional displays for potential and current. The devices are used for long term measurement and even with the monitor of the computer in sleep mode, the potential and current can be read off quickly.
This instrument equipped version approved well in practice, so we will maintain it.
In addition to the variant of the modular potentiostat with one or more modules, there is also a variant with additional electrometer inputs.
These inputs can be connected to additional reference electrodes to measure the potential at various points of a sample. The measurement and storage of these additional channels is already provided in our EcmWIn software. Depending on your hardware, up to 8 additional channels can be enabled and captured. The values are inserted in the data file as an additional column.
The PGU-MOD-16k was developed in cooperation with IKTS Dresden and was firstly special designed for the measurement of so called multi-sensor arrays. After the first pretests it showed up that this device is also suitable for other measurements where several samples must be measured parallel. The device contains 16 individual potentiostats. Each cell can be measured in 2 or 3 electrodes operation. For the 2 electrodes operation the reference electrode is internally short-circuited with the counter electrode, the setting is done by software. The potentiostats have each two current ranges. The maximum measuring current amounts to 4mA per potentiostat. The connection of the cells takes place via the built-in Sub-D connectors on the frontside. If needed, other connectors can be used.
The P-M 100 is a purely manually operated potentiostat. It is mainly dimensioned for hold experiments. The purpose is for example to analyze the cathodic disponding. According to requirements the device can be assembled with only one but also with up to 4 modules. The modulation current amounts to approximately ±12V, the current can be displayed with two ranges with 20mA and 100mA, the maximum current amounts to approximately 180mA. The device has digital instruments for current and voltage. An internal nominal voltage generator amounts to ±2V. No in- and output computer connections.
The PGU 10V-10A is a high current device for speration experiments or battery research. The construction is equal to the standard PGU devices. It is completely manual operable. Equipped with interface all standard methods are available. 8 current ranges provide also a sensible resolution of lower currents. As 20V device a higher output voltage is available. Optionally the polarization voltage can be raised accordingly. This can be necessary for example when poor conducting electrolytes are used. But it is also necessary when 12V batteries are tested at a higher modulation current as well as a higher polarization current.

The PGU 100V-10A is the big brother of our 100V standard device. Particularly for galvanic experiments or for anodization both high voltages and high currents are needed. Due to the high performance of this device it is equipped with a programmable power supply. Thereby, no excessive power dissipation must be dissipated as heat. However, this means a limitation of the control rate / speed. This device is not suitable for pulse experiments with rise times in the ms range.
This potentiostat / galvanostat can be used for standard and impedance measurements. This device has a signal generator for frequencies from 100µH up to 100kHz. A fast measuring module inside allows frequency measurement up to 100kHz as well. The integrated offset adjustment for current and voltage allows efficient amplification of lowest signals down to the lowest frequency range. Due to a specifically approximation procedure very low current signals can be reliable measured at lower fA-range with the result that impedances up to 200GOhms (where applicable even higher) are measurable. Furthermore all available standard methods in our software can be performed with the result that this device is universal.
The retrieved values of the impedance measurement are provided with frequency, real and imaginary part. To analyze the data we recommend Solatrons® software ZView™.
