DESCRIPTION
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.
