Visão geral

Combined pH electrode with double-junction system for pH measurements in nonaqueous media (e.g., for pHe in ethanol).

The electrode is equipped with a fixed ground-joint diaphragm which is insensitive to contamination, and the bridge electrolyte can be freely chosen (aqueous or nonaqueous).
When c(KCl) = 3 mol/L is used as bridge electrolyte, storage in storage solution is recommended. When a different bridge electrolyte is used, storage in the respectively used bridge electrolyte solution is recommended.
The two chambers for reference electrolyte ("INNER FILLING") and bridge electrolyte ("OUTER FILLING") are each filled with c(KCl) = 3 mol/l at the time of delivery.

    • Reliable measuring results over long periods of time can be guaranteed only if the pH glass membrane and the diaphragm receive preventive and regular care. Cleaning by etching with toxic chemicals or applying mechanical treatment to the diaphragm is not only complicated and expensive, it also accelerates the ageing of the pH glass electrode.The cleaning solution was developed for easy and gentle cleaning of pH glass electrodes. Regular use can considerably prolong their service life.This cleaning solution is also part of the pHit kit.
