CHI700E series is a universal double potentiostat, which can control the potential of two working electrodes in the same electrolytic cell at the same time. Its typical application is rotating ring disk electrode, and it can also be used in other cases where double working electrodes are needed. The double potentiostat can only be used for potential control and current measurement of two working electrodes in the same solution, rather than two independent potentiostats. The instrument includes a fast digital signal generator, a direct digital signal synthesizer for high frequency AC impedance measurement, a dual channel high speed data acquisition system, a potential current signal filter, a multistage signal gain, an iR drop compensation circuit, a dual potentiostat, and a constant current meter ( CHI760E ).
