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 ZAHNER PAD4 is a 4-channel add-on card for ZENNIUM Electrochemical Workstations. It introduces four additional parallel sampled signal inputs for cell voltage and impedance in fuel cell stacks and battery packs, with a common current.

The capacity of the Zahner Zennium is one PAD4-cards, supporting up to five channels, while the Zennium X can be extended by up to four cards, allowing a maximum count of 17 parallel channels.

PAD4-cards are plug ’n’ play – they are detected automatically on start-up and they are integrated in the Thales impedance series measurement support. Each input can be activated individually. The PAD4 may be combined with the basic ECW or with the ECW controlling a slave potentiostat or an electronic load, finally providing tests on stacks of up to 100V / 600A / 50 KW. High resolution 18-bits-AD-converters and a wide frequency range of 10 µHz - 250KHz make this solution extremely versatile.
