EmStat4S
The EmStat4S delivers desktop performance in the palm of your hand. The EmStat4S is a portable USB-powered Potentiostat, Galvanostat, and optional a Frequency Response Analyser (FRA) for Electrochemical Impedance Spectroscopy (EIS). The EmStat4S is controlled with PSTrace for Windows, or you can write your own MethodSCRIPT and control it from any platform or operating system.
Always a backup
Every EmStat4S is equipped with an internal storage of 500 MB, equivalent to 15 million data points. This means all your measurements can automatically be saved onboard as a backup. Measurements can be browsed and transferred to the PC easily using the PSTrace software for Windows.
Versions
The EmStat4S comes in two different versions:
- Low Range: current range from 1 nA to 10 mA (max. 30 mA)
- High Range: current ranges from 100 nA to 100 mA (max. 200 mA)
Both versions can be configured with optional EIS/FRA with a maximum frequency of 200 kHz.
See specifications for more information.
