Combined pH electrode with XRV1H-S7 filling - CHAUVIN ARNOUX

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