Combined pH electrode for pH titrations. This electrode is particularly suitable:
- for pH titrations in difficult, viscous, or alkaline samples
- at elevated temperatures
The fixed ground-joint diaphragm is insensitive to contamination.
Reference electrolyte: c(KCl) = 3 mol/L, storage in storage solution.
Alternatively: reference electrolyte for measurements at T>80℃: Idrolyte, storage in Idrolyte.
