摘要：
Reliability is the paramount requirement for industrial pH measurement followed by accuracy and temperature and pressure resistance. Automatically retractable probes, contactless connectors, and "intelligent electrodes" are typical developments of the last years to reach these goals. This article is to remind on the effects of temperature on the properties of electrodes, buffer and measuring solutions as well as on instrumentation and their influence on the measurement accuracy. The above mentioned development activities have no or only a little improving effect on these aspects.
