摘　　要：文中设计了一个以MCS-80C196KB单片微处理器为核心的自动pH测量系统。系统采用高灵敏度的离子选择性电极传感器,选用高精度的16位A/D数据转换器件、点阵液晶显示器件和微样本量的精确进液系统。设计的自动pH测量系统经调试和试用,表明硬件电路工作稳定、软件界面合理、精度较高、使用方便。A automatic pH measurement system was designed based on MCS - 80C 196KB microprocessor in this paper. In the system, the high sensitivity Ion selective electrode sensors, high-precision 16-bit A/D data conversion devices, Dot-matrix liquid crystal displays and micro-precision sample inlet system were adopt. The commissioning and testing resuits on the designed automatic pH measurement system show that the hardware circuits of the system works stably, and the software interface is reasonable. The system has high-precision and is easy to use.
