DESCRIPTION
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 Profitrode is available in other lengths under the following article numbers: - 6.0255.110: Length 17.8 cm- 6.0255.120: Length 31.0 cm
