Description
The Endress+Hauser Memosens CPS91E is a digital pH sensor for heavily polluted media, with an open-aperture reference that resists clogging by solids, emulsions and precipitates. It measures pH 0–14 at 0 to 110 °C and 0.8 to 14 bar, has an integrated NTC temperature sensor for compensation, and uses a low-maintenance stabilized gel electrolyte, with an ion-trap version for poisoning media.
Memosens technology transmits the signal inductively and digitally, stores calibration data in the sensor and supports predictive maintenance. It fits Pg 13.5 assemblies in four lengths, is IP68 and is approved for Zone 0 hazardous areas worldwide.
Argonmark Ltd supplies Endress+Hauser instruments across Bangladesh — Dhaka, Chattogram, Gazipur, Narayanganj and the gas fields, refineries, terminals and power plants beyond. Send us the model, range, process connection, output and any hazardous-area requirement, and we will confirm the right configuration, lead time and price.
