This combined single-rod measuring chain (platinum and reference electrode in one shaft) has a high-quality zirconium dioxide diaphragm with polymerized solid electrolyte. The additional salt supply in the form of rings improves the service life with media with fewer ions or with high flow rates. The single-rod measuring chain was specially developed for use in swimming pool and drinking water disinfection with relatively clean media. It can be used for a redox range of plus/minus 1500 mV and has a temperature resistance of -5 to +90 °C. The installation length is 120 mm.
