Unitrode
Beställningsnummer: 6.0259.100

Combined pH electrode for pH titrations. This electrode is particularly suitable:

  • for pH titrations in difficult, viscous, or alkaline samples
  • at elevated temperatures

The fixed ground-joint diaphragm is insensitive to contamination.

Reference electrolyte: c(KCl) = 3 mol/L, storage in storage solution.
Alternatively: reference electrolyte for measurements at T>80°C: Idrolyte, storage in Idrolyte.
