The ENDRESS+HAUSER Memosens CPS71E digital pH sensor is designed for chemical processes and is resistant to contamination, making it suitable for use in heavily polluted and aggressive media. With its unique ion trap, this sensor prevents poisoning of the junction and reference, ensuring a long sensor lifetime. It offers reliable measurement even in the presence of strong acids and bases. The CPS71E features Memosens 2.0 digital technology, which provides extended storage of calibration and process data for predictive maintenance. It can be pre-calibrated in the lab and quickly exchanged on site, reducing process downtime and operating costs. With ATEX, IECEx, CSA C/US, NEPSI, Japan, and INMETRO approvals, this sensor can be used in hazardous areas, zones 0, 1, and 2.
