摘要：

设计了一种低成本、高精度的三电极分析装置。此装置主要包括前端模拟电路部分、数字电路处理和上位机界面，利用TLV2262，TLV2264，ICL7650S搭建了前端模拟部分，主控芯片C8051F020完成了电压反馈控制和电流信号的采样及上位机通信。亚铁氰化钾氧化峰实验数据证实此装置运行稳定，可用于类似的实验中。

关键词: 三电极, C8051F020, 氧化峰

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.
