Description
The EmStat4R delivers near desktop-level performance in a compact and rugged enclosure, making it ideal for both laboratory and field applications. It combines potentiostat, galvanostat, and optional frequency response analysis (FRA) capabilities for electrochemical impedance spectroscopy (EIS).
The instrument can be controlled via PSTrace (Windows), PStouch (Android), or custom software using MethodSCRIPT™, enabling flexible integration into research systems or portable sensing platforms.
It is particularly suitable for low-current measurements such as electrochemical sensors and analytical applications.
