Profitrode (length 12.5 cm)

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
