Potentiostat PGU 10V-1A-IMP-S

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™.

The PguTouch is our latest Potentiostat/Galvanostat in a completely new design. A modern touch display substitutes the previous instruments and manual control elements.

The core of the device is a powerful yet low-power ARM-Cortex microcontroller, the ideal prerequisite for portable battery operation.


A 4-channel 24-bit analog-to-digital converter for data acquisition and a scanner with a 26-bit digital-to-analog converter give the device the characteristics of a high-quality laboratory instrument. The built-in SD card with 2 GB memory allows the storage of a considerable amount of data. The Ethernet interface is used to read out the stored data as well as for convenient operation of the device on a PC with our EcmWin software. This potentiostat/galvanostat can be used as a laboratory measuring station for more complex tasks as well as a field device for predefined measurement routines.

The PguEducation is the new potentiostat/galvanostat for schooling persons who like to discover the world of electrochemical measurements and want to make their first experiences with this subject. Also intermediate learners can do experiments and measurements with this tiny unit.


When connecting the PguEducation with a computer running our EcmWin Software it behaves like a normal potentiostat. Performing OCP, Constant value, Scan and Pulse measurements are supported. EIS or ECN are not feasible with this device.

A maximal current of 20mA some realistic measurements can be carried out. In cases a higher current is required you can also reduce the sample size to be inside of the possible current. With 6 ranges, the lowest current range is 1 µA. It is obvious that the resolution and the accuracy of a professional device cannot be reached in this range. Nevertheless also measurement can be done in this range.

With a compliance voltage of +- 10V and a polarization range of +-5V, the device is ideal for teaching and training. Moreover it is able to introduce in the typical nature of electrochemical measurements.
