The Arbin MSTAT4 is a four‑channel potentiostat/galvanostat station with a –2 V to +10 V range, up to 5 A current, and optional software features.
The MSTAT4 is a potentiostat/galvanostat station designed for battery, supercapacitor and electrochemical research. It offers four independent channels, each capable of operating as a separate PST/GST with its own reference electrode and voltage‑clamp functionality.
Hardware specifications include a –2 V to +10 V voltage range (‑5 V to +5 V optional), up to ±5 A current, 16‑bit resolution, and a 10 GΩ input impedance. The system is air‑cooled, provides TCP/IP networking, and can be expanded with auxiliary modules for voltage, temperature, pressure and pH inputs.
