Stanford Research Systems
The EC301 Potentiostat or Galvanostat, manufactured by Stanford Research Systems, provides electrochemists the freedom to qualify their labs with high compliance, research-grade instrumentation at a very attractive price.
It was designed with an electrochemical impedance spectroscopy (EIS) in mind. This means higher accuracy and less susceptibility to parasitic effects.
It has a built-in temperature measurement that makes it easy to acquire and plot temperature right along with the rest of the data.
