摘　　要：介绍了一种新研制的微机化pH分析仪。它用数据采集板PCL－818作A／D、D／A转换器，用PC微机作数据采集、数据处理和发送控制信号。用C语言编写软件，可以完成数据存贮、曲线打印、谱图分析及参数校正等功能。用该pH分析仪对镇江自来水样品作了测试，绘制了pH－t曲线，并且作了酸碱溶液pH值的自动滴定，实验结果令人满意。A microcomputerized pH analyzer has been designed by using PCL-818 (made by Advanctech co., Ltd)as A/D and D/A converter. Data acquisition and processing and control signal sending are performed by a PC microcomputer. The software written with C language nd the functions of data storage, curve printing, spectra analysis and parameter correction . The pH ～t curves of drinking water samples and the pH values of ecid and basic solutions obtained by automatic titration are presented. The test results are satisfactory
