EtOH-Trode

EtOH-Trode
Beställningsnummer: 6.0269.100

Combined pH electrode with double junction construction for pH measurements in non-aqueous media (e.g., for pHe in ethanol).

The electrode is equipped with a fixed ground-joint diaphragm which is insensitive to contaminaiton, and the bridge electrolyte can be freely chosen (aqueous or non-aqueous).
When c(KCl) = 3 mol/L is used as bridge electrolyte, storage in storage solution is recommended.
When another bridge electrolyte is used, storage in the used bridge electrolyte.
