This combined single-rod measuring chain (glass and reference electrode in one shaft) has a high-quality zirconium dioxide diaphragm with a biocompatible special hydrogel validated according to EN ISO 10993-5. 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, for example, in hygienic applications, sterilization and fermentation processes in the food and pharmaceutical industries as well as universal use in non- and slightly contaminated aqueous media as well as in drinking, salt and sea water applications. 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 up to 6 bar. The electrode has an integrated Pt1000 to measure the medium temperature. The installation length is 120 mm.
