摘　　要：介绍了以89S51单片机为中央处理器的电导率测试仪的工作原理、硬件电路图和软件设计。该测试仪采用了接触式电导传感器与AD0804模/数转换器将所采集的模拟信号转换为数字信号,经中央处理器计算出电导率值并显示在1602LCD显示屏上。它具有操作方便、适用性强等优点,用来检测食用油中是否掺有地沟油。A rapid detecting instrument for qualified oil based on 89S51 microcontroller is introduced. The hardware structure and principle of the software design of the instrument are given. A conductivity sensors and a A/D converter are used for signal collect and change respectively, the central processing unit calculate the results then display on the 1602LCD.This instrument operate easily and applicably, thus can be used in edible oil adulteration.
