Electrochemical Workstation ZENNIUM E
Electrochemical Workstation
Compact High Performance
The ZENNIUM E is a high-performance electrochemical workstation at a surprising affordable price. Besides a potentiostat / galvanostat it bears a frequency response analyzer unit (FRA) for promoting impedance spectroscopy. It provides high-end features like a frequency range up to 2 MHz, a 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 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 and potentiostats / galvanostats of the high-end class. The ZENNIUM E is a revolution in the field of compact electrochemical workstations. Since it is equipped with a freqency response analyzer (FRA) unit on-board for the immediate promotion of impedance spectroscopy it can be seen as a unique tool for nearly all kinds of electrochemical measurements during the daily research routine. It provides a wide frequency range from 10 μHz to 2 MHz, an output current up to ±2.0 A and a 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:
