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.


Displays and Luminescence

LCDs, LEDs, OLEDs: Liquid crystaline displays, light emitting diodes, organic light emitting diodes. Research on display technology, material characterization and charge extraction. 

Interactive, flexible liquid crystals displays (LCDs) will determine our visual and touching senses in the near future and determine the way how we will see the world through multimedia.

Other light emitting devices such as diodes (LEDs) and electrochemical cells (LECs) are at the edge of revolutionizing today's light technologies, making them less energy consumable and more environmental friendly.

Electronic consumer products, automotive vehicles and many other applications are already equipped with latest display and LED technologies, which make our daily lifes more convenient.

CIMPS mdtr/ois - Synchronous Multi Spectral DTR (OIS)

Synchronous Multi Spectral DTR (OIS) with Parallel Impedance Measurement System
With this option your CIMPS system gets the ability to investigate electrochromic systems, displays, PDLCs, smart windows...


Light Sources

Over 50 monochromatic light sources from UV to IR are available. The portfolio includes high power white and coloured LEDs, tungsten lamps and tuneable light sources.

PEC - Cells

The PECC-1/PECC-2 are specially tailored for testing electrode materials with photoelectrochemical techniques. Several mounting options for samples offer flexibility for various tasks.

Light Exclusion Box

The CIMPS Light Exclusion Box (LEB) is an indispensable supplement for all CIMPS applications using CIMPS LED light sources. Next to its function to protect the sample setup from light, at the same time, it works as a Faraday’s cage.
