75-4B fast polarography all using domestic integrated circuit assembly, the line is simple, reliable performance. The utility model comprises a linear scanning circuit and an automatic limiting device, a three-electrode potentiostatic circuit which automatically compensates for the IR drop of the internal resistance of the solution, a zero-resistance galvanometer circuit and a residual current compensation device, a differential circuit, a damping device and a regulated power supply. The instrument can be equipped with mercury drop electrodes for classical polarographic analysis, but also with a variety of solid electrodes for forward voltammetry and reverse stripping voltammetry analysis, and polarographic catalytic wave analysis. Can record the normal voltammetry curve, can also record the derivative voltammetry curve, therefore, has a high sensitivity and demultiplexing ability to reproduce
