DIN Standards Committee Materials Testing

Abstract

This document contains requirements for pH transmitters for potentiometric pH and ORP measurement in industrial plants with pH sensors or ORP electrodes. Due to their practical importance, only the connection of a pH glass electrode or precious metal electrode for redox is described in more detail. Other electrodes (ISFETs, antimony and hydrogen electrodes) are used in selected applications, but are not part of this standard. This document was prepared by the working committee NA 062-09-21 AA "pH measurement technology" of the DIN Standards Committee for Materials Testing (NMP).
