Description

The pH electrode is the main actor of pH measurement. It requires special care and attention. The removal of contamination is required before the electrode can be re-calibrated and used for another measurement. Rinsing with deionized water is not sufficient when silver sulfide contamination is present; Thiourea is recommended in this case.
