ZENNIUM and IM6. These devices are developed using 30 years of experience in producing high-precision electrochemical workstations of the high-end class. They provide a frequency range up to 4 MHz (ZENNIUM) / 8 MHz (IM6), an output current up to ±2.5 A (ZENNIUM) / ±3.0 A (IM6) and fast signal processing. Special measurement techniques guarantee an ultra high accuracy and a minimal interference with the test object.

ZENNIUM/IM6 come bundled with the outstanding THALES-Z (Zennium release) software package which offers all standard methods and more at a mouse click. This is why the ZENNIUM/IM6 can easily be adapted to very different measurement requirements. Furthermore, with the manifold options available, the ZENNIUM/IM6 is able to grow with its tasks. It is best suited for investigations on fuel cells, batteries and solar cells as well as on membranes and sensors or on coatings and laminates, to name only a few.


  • ultra low-noise potentiostat
  • wide frequency range dual DDS FRA
  • high CMRR precision U/I-amplifiers
  • PulSAR® state-of-the-art differential 18 bit ADCs for AC
  • connectors optimized for High Z & Low Z
  • 4/9 extension card slots
  • 410 MIPS (Dhrystone 2.1) V4e ColdFire® signal processor
  • floating USB 2.0 interface

The highest priorities for the developement and production of the ZENNIUM instruments are accuracy and reliability. The accuracy map of the ZENNIUM clearly shows the high quality of the hardware. These specifications are proofed by measurements for practical use, based on the high-end components we use. They are not only calculated by the theoretical specifications of some components.

Software The powerful Thales software package is part of the standard equipment of each IM6 and ZENNIUM system. It provides a multitude of measuring and analysis methods. The Thales software provides unique features for the acquisition and analysis. The most prominent examples are SCRIPT and SIM. SCRIPT offers you to program user defined combinations of all types of electrochemical measurements, mathematical analysis, algorithms, documentation and data export to a reproducible, fully automatic process. With the outstanding features of SIM you are able to create equivalent circuits and fit the measurement data to these models. The ZHIT feature of SIM helps you to validate your impedance spectra.

For evaluation only it is also possible to run Thales software package on a ThalesBox. The ThalesBox provides a single user licence of Thales. So you can process your recorded data on a simple PC or Laptop while your tests still run on the IM6 or ZENNIUM.
