SM23 Electrode for pH/Redox
Brand: Yokogawa Electric CorporationThis sensor is suitable for long term, reliable Sodium ion monitoring, as well as several other cations. Despite the name “Sodium sensor”, the most common application of the SM23 is pH measurement.
In this application, the SM23 is used as a reference electrode – dramatically improving measurement reliability in many demanding applications.
Typical applications for the SM23 are found in industrial process control.
