E+H Memosens CPS71E pH Sensor

The E+H Memosens CPS71E digital pH sensor contains a digital pH electrode for chemical process with an ion trap for poison-resistant reference. The electrode's ion trap prevents poisoning of the junction and reference, making it resistant to strong acids and bases and ensuring a long sensor lifetime. The sensor includes process technology and monitoring of processes with rapidly changing pH values and a high proportion of electrode poisons such as H2S. The connection for this sensor is an inductive, contactless connection head with Memosens 2.0 technology.

The Memosens 2.0 technology allows for trend identification and predictive maintenance due to the extended storage of calibration and process data. The optional pressurized reference also allows for reliable measurement in blocking media such as dispersions. Additionally, the digital pH sensor is approved by ATEX, IECEx, CSA C/US, NEPSI, Japan, and INMETRO for use in hazardous areas Zone 0, Zone 1, and Zone 2. The process temperature ranges from 32 to 284°F (1 to 140°C) and the process pressure ranges from 0.8 to 14 bar (11.6 to 203 psi).
