ZAHNER – ZENNIUM pro

ZAHNER ZENNIUM pro Electrochemical Workstation

The all-purpose instrument

The ZENNIUM pro is a modular electrochemical workstation including a potentiostat / galvanostat and a frequency response analyzer (FRA) unit with a frequency range up to 8 MHz at ±3 A and at a compliance voltage of up to ±28 V. With an input impedance of more than 10 TΩ || 5 pF the workstation is suitable for a wide range of electrochemical tasks.

The electrochemical measurement capabilites of the ZENNIUM pro workstation can be extented by adding up to five additional plug-in cards such as TEMP/U or EPC42. For example, the latter makes it possible to control up to four additional external devices such as power potentiostats of the PP/XPot-series (boosters) or electrical loads of the EL-series. Thus, our ZENNIUM pro electrochemical workstation is able to provide even more advanced measurement methods and allows us to satisfy any of your electrochemical research requirements.
