The ENDRESS+HAUSER Memosens CPS71E digital pH sensor is designed for chemical processes and offers reliable measurement even in heavily polluted, aggressive media. With its unique ion trap, the electrode prevents poisoning of the junction and reference, ensuring a long sensor lifetime. The optional pressurized reference allows for reliable measurement in blocking media. This pH sensor is equipped with Memosens 2.0 digital technology, providing extended storage of calibration and process data for predictive maintenance. It is suitable for processes in the chemical industry with high levels of electrode poisons such as H2S and quickly changing pH values. With ATEX, IECEx, CSA C/US, NEPSI, Japan, and INMETRO approvals, it can be safely used in hazardous areas.
