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 IM6 is our high class A-level modular electrochemical workstation having a potentiostat / galvanostat and a frequency generator and response analyzer unit (FRA) on-board within its standard configuration. This grants a frequency range up to 8 MHz at ±3.0 A and a compliance voltage of ±14 V. Eight free extension slots provide huge expansion capability for all fields of application.

High flexibility, high precision and high reliability are the basic elements which make the advanced concept of the IM6 unique!

Equipped with a programmable potentiostat, a pair of high precision amplifiers for current and potential, a flexible frequency generator/analyzer and four slots for additional input and output modules the IM6 is designed for nearly all measurement situations in the electrochemistry lab. Specially designed for spectrum analysis in the electrochemical field, the modular hardware concept of the IM6 allows you to configure the IM6 for applications far beyond impedance spectroscopy. With the appropriate hardware and software modules you can perform nearly all important data acquisition and analysis techniques which are required by electrochemical applications. Its versatility and its application range can easily be extended in connection with our external power potentiostats PP201, PP211, PP241, and XPot.

The Electrochemical Workstation IM6 has been developed with a background of 15 years of know-how in the field of impedance spectroscopy and electrochemical measurement techniques. It is based on the high end data acquisition system AMOS/ANDI and has therefore access to all its hardware and software modules. Very special, partially patented measurement and analysis techniques guarantee highest accuracy and minimal interference with the test object. The great number of different modes of acquisition and analysis as well as the unique upgrade concept make the IM6 an indispensable universal measurement tool in electrochemical laboratory.

IM6 comes bundled with the outstanding Thales Z 3 software package which offers all standard methods and more at a mouse click. This is why the IM6 can easily be adapted to very different measurement requirements. Furthermore, with the manifold options available, the IM6 is able to grow with its tasks:

  • Compliance Voltage up to ±120 V
  • Output Power up to ±40 A / ±20 V
  • Input Impedance up to 10 TΩ
  • Input Current up to 200 A
  • 16 Additional Channels for True Parallel Impedance Spectra
