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 PP241 is a 4-quadrant power potentiostat designed to apply and sink high currents up to ±40 A at a voltage range of ±5 V. The total power dissipation of the PP241 is 200 W.

The PP-Series potentiostats are controlled by an EPC42, a plug-in module for the ZENNIUM-series Electrochemical Workstations. Due to the built-in microprocessor, each EPC42 can address up to four PPSeries potentiostats. Up to four EPC42 cards can be installed in an ZENNIUM-series workstation. In total, up to 16 PPs can be controlled by one ZENNIUM. Each potentiostat will hold the control parameters from one access to the next one, so that no potential or current disturbances can occur while scanning the potentiostats. If series measurements are performed with more than one PP-Series potentiostat, spectra are taken from all modules in a definable order.

The PP-Series is embedded completely in the ZENNIUM environment. Thus, all acquisition and analysis techniques that run on the ZENNIUM workstation can be applied with the power potentiostats as well. The installation of one or more PP-Series potentiostat will upgrade your ZENNIUM to an even more versatile, high-current electrochemical workstation.

The PP-Series potentiostats can also be controlled by a Windows®-PC. In this case they provide methods, summarized in the table below. They also work as a LabView® Virtual Instrument under the LabView® software. To implement the PP-Series potentiostats into existing test environment, a supporting DLL is available on demand.

You can control the PP-Series potentiostats in a mixed mode with an ZENNIUM and a PC in parallel. Both devices can be connected and disconnected during operation.
