Ingsens IGS4200 series are computer-controlled, fully automatic and power electrochemical measurements. The system contains an advanced MCU for digital function generator with a high speed data acquisition circuit. IGS4210 works as a potentiostat/galvanostat while IGS4220 and 4230 have AC impedance. The potentiostat/galvanostat uses a 4-electrode configuration, allowing it to be used for liquid/liquid interface measurements and eliminating the effect of the contact resistance of connectors and relays for high current measurements. The instruments are designed for electrochemical applications that require relatively large current and high compliance voltage, such as battery studies, supercapacitors, electrolysis, and electroplating. The potential control range is ±10 V, the current range is ±2 A, and the compliance voltage is ±25 V.
