Profitrode (length 31 cm)

Combined pH electrode with double-junction construction, installation length 31.0 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 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 used bridge electrolyte.
