Our Electrochemical Workstations ZENNIUM X / ZENNIUM Pro / ZENNIUM  base on an universal and modular data acquisition system. Together with the THALES software package we offer all standard electrochemical methods at a mouse click.



CIMPS is an universal photo- and spectro-electrochemical workstation for a wide field of applications. You can easily extend the basic CIMPS system with various options for special fields of photo-electrochemical research.


Energy Storage & Conversion

Our power potentiostats, electronic loads and multi-channels acquisition systems provide a smart system for research and investigation on batteries, fuel cells and super caps.



Electrochemical noise has become popular as a new method of corrosion detection and prevention. ZAHNER has developed the CorrElNoise® technique, the first method to obtain both, potential noise and current noise from one electrochemical source.



The power cell multiplexer PMux can be used with ZENNIUM electrochemical workstations as well as with an external potentiostat from the EL-Series, PP-Series and XPot. It can manage a cell current up to ±5 A.

There are two configurations of the PMux. The PMux-S can measure 16 individual cells compared with the PMux-P which is configured to measure 16 segmented cells for example of a fuel cell.

The PMux-S is configured for sequentially measuring through up to 16 individual cells using either the internal potentiostat of the IM6/Zennium or an external potentiostat of the PP-series or an electronic load of the EL-series.

The PMux-P is configured for sequentially measuring through up to 16 segments of a segmented fuel cell. For that application a PP-series potentiostat or an EL-series electronic load is used for loading all segments except the one which is measured. The measurement is done by the internal IM6/Zennium potentiostat. The software carries out sequential measurements through all segments of the fuel cell. With one PMux-P these are up to 16 segments. Up to 3 PMux-P modules can be stacked for a total of up to 48 segments. Both, the PP and the IM potentiostat have to be connected to the PMux-P.

Each PMux device includes a RMux addon card for controlling the cell multiplexer. This means that every PMux needs an extension slot of the IM6/Zennium.
