Our electrochemical workstations IM6 and 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.

Light Exclusion BoxLight Exclusion Box

The CIMPS-LEB is an indispensable supplement for all CIMPS applications using CIMPS-LED light sources. It serves as a light exclusion box and at the same time as a Faraday’s cage.

The CIMPS optical bench fits directly into a fixture. The box is compatible with all single wavelength light sources as well as with the tunable light source TLS03. The cover with top and attached front and sides can be tilted up granting free access to the complete optical bench. Three blanketed openings on three sides are leading all cables into the box but block the light.

Controlled Light Intensity

CIMPS in action


Photo-electrochemical measurements can only be reliable and of high accuracy if the light source is emitting a constant light of an exactly known intensity. This cannot be achieved by controlling the current feeding the light source but only by continuously controlling the light intensity by a calibrated photo sensor. This is what making the difference using CIMPS.

The Next Generation of MultiSine Excitation

Thales now supports intelligent Multi-Sine!

In the past multi-sine methods were suffering from a couple of severe disadvantages. The new "intelligent Multi-Sine" method developed by Zahner overcomes this drawback.
