This combined single-rod measuring chain (platinum and reference electrode in one shaft) has a dirt-repellent PTFE ring diaphragm with polymerized, highly elastic gel. This prevents deposits and blockages and achieves a fast response time. A double chamber with double diaphragm sealing prevents electrode poisons such as sulfides, amines or chromates from damaging the reference electrode. The salt reserve integrated in the reference electrode enables a longer service life, especially in media with lower conductivity. Each electrode is individually tested and supplied with a quality certificate. The electrode is made from physiologically harmless and FDA-listed materials and is RoHS2-compliant with a lead-free shaft glass. Only the selection of high-quality materials and components enables use in, for example, chromate reduction, nitrite oxidation, swimming pool and drinking water disinfection with heavily contaminated media. An internal pressure buffer compensates for temperature-related volume changes in the reference electrode space and allows process pressures of up to 13 bar. With its wide temperature range of up to 135 °C, the electrode can be used in demanding applications. The installation length is 120 mm.
