Description
Metrohm Profitrode 6.0255.100 Combined pH Electrode
Combined pH electrode with double-junction construction, installation length 11.3 cm. This electrode is suitable for pH measurements/titrations of samples:
that 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 replaced 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 used bridge electrolyte.
The electrode is new in original packaging, images form part of the description
