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 EL1000 was designed to investigate single cells or complete stacks up to 100 V. Adding an additional external electronic load, the maximum current of 200 A can be raised up to 680 A and the corresponding power from 1000 W to 68 kW.

Due to the limited potential span resulting from the combination of chemical elements or compounds, a huge number of cells have to be stacked to achieve a technical practicable voltage, say for instance 100 V. The EL 1000 was designed to investigate complete stacks in combination with a ZENNIUM X, ZENNIUM pro or ZENNIUM Electrochemical Workstation for instance for impedance measurements. Adding an additional external electronic load, the power can be raised up – adding the PAD4 to the controlling workstation, individual segments of the stack can be investigated separately.

The EL-Series potentiostats are controlled by an EPC42, a plug-in module for the electrochemical workstations ZENNIUM X, ZENNIUM pro or ZENNIUM. Each EPC42 can address up to four EL-Series potentiostats. Up to four EPC42 cards can control up to 16 ELs by one ZENNIUM X, ZENNIUM pro or ZENNIUM electrochemical workstation. 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 ZENNIUM-series environment. Thus, all acquisition and analysis techniques that run on the ZENNIUM electrochemical workstations can be applied with the EL-Series potentiostats as well. The installation of one or more EL-Series potentiostat will upgrade your ZENNIUM workstations to even more versatile, high-current electrochemical instruments.
