EmStat4M Module

Tested & calibrated potentiostat module

  • Desktop performance in the palm of your hand
  • Enables rapid prototyping
  • Easy to reproduce measurements using MethodSCRIPT™
  • Many code examples for different languages and platforms


The EmStat4M is a potentiostat/galvanostat module supporting all common electrochemical techniques, including Electrochemical Impedance Spectroscopy (EIS). The EmStat4M can be evaluated with our PSTrace software for Windows. You can write your own applications for the EmStat4M module using our .NET libraries or MethodSCRIPT™ and control it from any platform or operating system.

  • Low Range (LR): current range from 1 nA to 10 mA (max. 30 mA)
  • High Range (HR): current ranges from 100 nA to 100 mA (max. 200 mA)
