This combined combination electrode (glass and reference electrode in one shaft) has a dirt-repellent PTFE ring diaphragm with polymerized, highly elastic gel. This prevents deposits and blockages and a quick response time can be achieved. A double chamber with a double diaphragm seal prevents electrode poisons such as sulfides, amines or chromates from damaging the reference electrode. With the salt reserve integrated in the reference electrode, a longer service life can be achieved, especially in media with lower conductivity. Each electrode is individually tested and delivered with a quality certificate. The electrode is made of physiologically safe and FDA-listed materials and is RoHS2-compliant with a lead-free stem glass. Only the selection of high-quality materials and components enables, for example, use in the chemical industry, industrial wastewater technology, electroplating, power plants and waste incineration plants as well as in the sugar industry. An internal pressure buffer compensates for temperature-related changes in volume in the reference electrode area and allows process pressures up to 13 bar. With a wide temperature range up to 135 ° C and a large pH range from pH0 to pH14, the electrode can be used in demanding applications. The electrode has an integrated Pt1000 to record the medium temperature. The installation length is 120 mm.
