The EmStat4S delivers desktop performance in the palm of your hand. The EmStat4S is a portable USB-powered Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The EmStat4S is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.

The EmStat4S comes in two different versions:

  • Low Range: for lower currents and potentials
  • High Range: for higher currents and potentials

Both versions can be configured with optional EIS/FRA with a maximum frequency of 200 kHz.
