Polilyte HT sensors have been designed to withstand demanding industrial processes in chemical, petrochemical, process water, and water treatment applications. The sensor has a maintenance-free design, as clogging is eliminated by the two single-pore junctions that enable direct contact between the Polisolve reference electrolyte and the sample, ensuring optimal measurement performance. Polilyte HT sensors show excellent measurement accuracy in highly alkaline solutions as well as in samples with very low conductivity. They are steam-sterilizable, autoclavable, and suitable for clean-in-place (CIP) procedures. The sensor offers exceptional stability and robustness, even at high temperatures, while the Hamilton PHI glass ensures minimal signal drift after cleaning and high chemical resistance. Integrated Memosens_^™ technology enables safe, contactless digital signal transmission, enhancing data reliability and simplifying sensor handling. _{Memosens™ is a trademark of Endress+Hauser.}
