Power Potentiostat PP242

  • The PP242 is a 4-quadrant power potentiostat designed to apply and sink high currents up to ±40 A at a voltage range of up to ±5 V (max. power output 200 W).
  • For medium power applications, the PP242 is used as an extension of the ZENNIUM series potentiostat.
  • Besides an extension, the PP242 power potentiostat can also be used in stand-alone mode for standard DC measurements i.e., charging/discharging of batteries.

Application areas

  • Power extension of ZENNIUM potentiostat for fuel cells, or electrolyzer single cell measurements.
  • Typical application for the PP242 is the complete electrochemical investigation of single fuel cell or electrolyzer systems.
  • Optimal system for invastigation of large single cell fuel cells with CV and LSV.
  • Possible integration in a Python work environment.

    Zahner-Elektrik GmbH & Co. KG

    Since 1976, Zahner is manufacturing potentiostats for use in the field of electrochemistry. With a core competence in impedance spectroscopy, Zahner has designed its potentiostats with the modularity concept that can be customized to the needs of the customers. Zahner potentiostats can be easily extended for medium power (up to 200 W) and high power (up to 68 kW) applications. In addition, the potentiostats can also be equipped with addon cards which further increase their functionalities i.e., with PAD4 cards, Zahner potentiostats can simultaneously record multiple spectra from each segment of a fuel cell or electrolyzer.
