Abstract:

       We design a lowcost and highprecision threeelectrode analysis device. It includes frontend analog circuit, digital circuit and PCsoftware. Its frontend analog circuit consists of TLV2262, TLV2264and ICL7650S.Chip C8051F020 performs voltage feedback control, current signal sampling and communication with PC. Experimental data of potassium ferrocyani oxidation peak show that this device is stable and can be used in similar experiments.

Key words: three electrodes, C8051F020, oxidation peak
