Electrochemical Workstation Zennium

The ZENNIUM is a modular electrochemical workstation with a frequency range up to 4 MHz at ±2.5 A and a compliance voltage of ±14 V. With an input impedance of 1 TΩ || 5 pF the workstation is suitable for a wide range of electrochemical tasks.

For special fields of application you can extend the capabilities of your Zennium with probes, addon cards and external potentiostats (boosters).

 

ZENNIUM was developed using our 30 years of experience in producing high-precision electrochemical workstations of the high-end class. ZENNIUM provides a wider frequency range from 10 μHz to 4 MHz, an output current up to ±2.5 A and fast signal processing. Special measurement techniques guarantee an ultra high accuracy and a minimal interference with the test object.

ZENNIUM 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 can easily be adapted to very different measurement requirements. Furthermore, with the manifold options available, the ZENNIUM is able to grow with its tasks:

  • Compliance Voltage up to ±120 V (CVB120)
  • Output Power up to ±40 A / ±20 V (External Potentiostats)
  • Input Impedance up to 1000 TΩ (HiZ Probe)
  • Input Current up to 200 A (EL1000)
  • 4 Additional Channels for True Parallel Impedance Spectra (PAD4)
