pH计的检测元件主要由玻璃电极和参比电极构成。对过程pH计来说,电极的清洗、电极特性的校正是必不可少的。pH计的维护工作量很大,一般比温度、压力、流量检测仪表大3—5倍。因此实现电极清洗和校正的自动化非常重要。具有近四十年生产pH计历史的日本电气化学计器,最近又生产了HBM-51型微机化酸度计,可以实现包括电极清洗、电极特性校正在内的全自动校准。它主要由检测、校正装置和pH指示转换器组成。本文就这两部分及自
The pH meter’s detection element is mainly composed of a glass electrode and a reference electrode. For the process pH meter, the electrode cleaning, the correction of the electrode characteristics is essential. pH meter maintenance workload, generally larger than the temperature, pressure, flow measurement instrumentation 3-5 times. Therefore, it is important to automate electrode cleaning and calibration. Japan has nearly 40 years of history of the production of pH meter electrochemical instrument, and recently produced the HBM-51-based computerized acidity meter, including electrode cleaning, electrode calibration features, including automatic calibration. It is mainly composed of detection, calibration device and pH indicator converter. This article on these two parts and from
