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 electronic load EL300 is an one-quadrant potentiostat designed to sink currents up to 100 A at a total power of 100 W (air cooled) and up to 300 W (water cooled).

The EL-Series potentiostats are controlled by an EPC42, a plug-in module for the Electrochemical Workstations IM6 and Zennium. Each EPC42 can address up to four EL-Series potentiostats. Up to four EPC42 cards can control up to 16 ELs by one IM6/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 EL-Series potentiostat, spectra are taken from all modules in a definable order. The EL-Series is completely integrated into the IM6/Zennium environment. Thus, all acquisition and analysis techniques that run on the IM6/Zennium can be applied with the EL-Series potentiostats as well. The installation of one or more EL-Series potentiostat will upgrade your IM6/Zennium to an even more versatile, high-current electrochemical workstation.
