Electrochemical Workstation Zennium E

The Zennium E is a high-performance electrochemical workstation at a surprising affordable price. It provides high-end features like frequency range up to 2 MHz, max. current of ±2.0 A, a controlled voltage of ±12 V and an input impedance of 10 TΩ || 5 pF. The Zennium E is a perfect workstation for a wide range of electrochemical applications with the focus on corrosion, coatings and laminates.

It can be extended by a number of ZAHNER probes.

 

Zennium E was developed using our 35 years of experience in producing high-precision electrochemical workstations of the high-end class. The Zennium E is a revolution in compact electrochemical workstations. It provides a wide frequency range from 10 μHz to 2 MHz, an output current up to ±2.0 A and fast signal processing. Special measurement techniques guarantee an ultra high accuracy and a minimal interference with the test object. The Zennium E can be easily switched from grounded to floating operation.

Zennium E 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 Zennium E can easily be adapted to very different measurement requirements. Furthermore, with the probes available, the Zennium E is able to grow with its tasks:

  • Compliance Voltage up to ±120 V (CVB120)
  • Input Impedance up to 1000 TΩ (HiZ Probe)
  • FRA interface to 3rd-party electronic loads or potentiostats (FRA Probe)
