摘要
介绍了一种智能电导率仪的测量原理和软硬件结构。以STC89C58RD＋单片机为核心，结合电导测量电路，可以实现量程自动选择、人机交换界面、温度补偿、时间显示、USB接口等功能。
The software and hardware structure,as well as its measuring principle,of an intelligent conductance device are introduced in this paper. Based on singlechip of STC89C58RD＋ and the conductance measuring circuit,this device achieves auto-gearing and temperature compensation, and it also contains man-machine interfaces, time display unit and USB connector.
