EZstat Pro

Potentiostat Galvonostat

The EZstat Pro potentiostat/galvanostat uses a versatile menu-driven waveform generator (periodic or aperiodic) with preset battery cycling, Tafel plots, and cyclic voltammetry procedures. Users can program sequences of steps blending current and potential control with a resolution of 8 uS/point. EZstat Pro can perform electrochemical impedance spectroscopy (EIS) and uses active IR compensation. The instrument can interface with the EZpump peristaltic pump for flow batteries and fuel cells.
