EmStat4R
The EmStat4R delivers desktop performance in a rugged enclosure. The EmStat4R is a portable Battery or USB-powered Potentiostat, Galvanostat, and optional a Frequency Response Analyzer (FRA) for Electrochemical Impedance Spectroscopy (EIS). The EmStat4R is great for applications that require low currents, from 30 mA down to picoamps, such as sensor applications. The EmStat4R is controlled with PSTrace for Windows, the Android app PStouch, or you can write your own MethodSCRIPT and control it from any platform or operating system.
Features
