Metrohm, 6.0020.4300, dProfitrode

Digital, combined pH electrode for OMNIS with double-junction system. This electrode is suitable for pH measurements/titrations of samplesthat contaminate the reference system of the electrode (e.g., galvanic baths, samples containing sulfides)for which potassium chloride c(KCl) = 3 mol/L cannot be used as reference electrolyte (e.g., reaction of potassium or chloride with sample)The electrode is equipped with a flexible ground-joint diaphragm which is insensitive to contamination and which can be exchanged when needed.
When c(KCl) = 3 mol/L is used as bridge electrolyte, storage in storage solution is recommended.
The bridge electrolyte can be easily replaced with a suitable electrolyte (e.g., potassium nitrate c(KNO₃) = 1 mol/L (6.2310.010)). Storage in the bridge electrolyte used.
dTrodes can be used on OMNIS Titrators.
