Combined pH electrode with XRpt1-BNC filling - CHAUVIN ARNOUX

- Combined electrode for pH measurement (Measurement electrode + reference electrode = in the same body) - Protected in PVC body -> more robust, limits electrode breakage - Universal glass (type H), allows precise measurements up to pH 12 - Glass is the element sensitive to oxonium ions (H3O+(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, KCl 1 mol/L
