Description
The Endress+Hauser Memosens CPS76E is a combined digital electrode that measures pH, ORP and rH at the same time. Its poison-resistant reference with an ion trap and acrylamide-free gel electrolyte is designed for chemical processes with rapidly changing pH and media containing electrode poisons such as H₂S, and it is CIP/SIP capable and autoclavable.
It covers 0–14 pH and ±1500 mV from 0 to 140 °C at up to 14 bar absolute. Memosens technology transmits the signal digitally and contact-free, stores calibration and operating history in the sensor head, and detects glass breakage and reference blockage. It carries ATEX, IECEx, CSA and other approvals for Zone 0, 1 and 2.
Argonmark Ltd supplies Endress+Hauser instruments across Bangladesh — to pulp and paper mills, water and effluent treatment plants, chemical, textile, food and power plants in Dhaka, Chattogram, Gazipur, Narayanganj and beyond. Send us the model, measuring range, process connection, wetted materials and output you need, and we will confirm the right configuration, lead time and price.
