Combined pH electrode with filling XRV1H-S7 - CHAUVIN ARNOUX

- Combined electrode for pH measurement (Measuring electrode + reference electrode = in the same body)
- Protected in PVC body -> more robustness, limits electrode breakage
- Universal glass (type H), allows precise measurements up to pH 12

Glass is the element sensitive to oxonium ions (H30+(aq)) when the electrode is immersed in an aqueous solution; there is indeed a potential difference on either side of the glass membrane due to the different ion exchanges between the membrane and the solution. Liquid electrolyte, KCI 1 mol/L
