Product Overview
E+H Memosens CPS62E Digital ORP Sensor
Memosens CPS62E
The Endress+Hauser Memosens CPS62E is a digital ORP sensor specifically engineered for high-precision oxidation-reduction potential monitoring in hygienic, bioprocess, and sterile liquid applications. Equipped with Memosens 2.0 digital technology, a poison-resistant reference system with an ion trap, and a CIP/SIP-resistant design, it delivers exceptional measurement stability and contactless data transmission in fermenters and bioreactors.
Precision Digital ORP Measurement for Hygienic & Sterile Processes with Endress+Hauser Memosens CPS62E
The Endress+Hauser Memosens CPS62E is a premium digital ORP (redox) electrode specifically developed for demanding biopharmaceutical, biotechnology, food and beverage, and fine chemical process environments. Engineered to thrive in sterile bioreactors, fermenters, and sanitary process lines, the CPS62E delivers fast, highly reproducible oxidation-reduction potential measurements even when exposed to aggressive CIP chemicals, steam sterilization, or process poisons such as hydrogen sulfide ($H_2S$).
Poison-Resistant Ion Trap & Biocompatible Construction
Electrode poisoning from sulfides, heavy metal ions, or organic compounds is a primary cause of reference electrode drift and premature failure in bioprocessing and industrial fermenters. The Memosens CPS62E solves this problem with an advanced gel reference system featuring a specialized ion trap. This ion trap effectively blocks hostile chemical species from reaching the $Ag/AgCl$ lead, dramatically increasing operational longevity. Additionally, the sensor is constructed from biocompatible, cytotoxicity-certified materials and is free from acrylamide and animal-derived components, ensuring full compliance with stringent hygienic safety standards.
Thermal Shock Resilience & Flexible Installation
Designed for harsh thermal environments, the CPS62E tolerates rapid temperature shifts and full autoclaving up to 140 °C (284 °F). Its pressurized gel reference system allows for upside-down installation without compromising measurement accuracy or risking air bubble entrapment at the sensing tip.

FAQ
Q1: What makes the Memosens CPS62E suitable for hygienic bioprocesses?
Answer: The CPS62E features a biocompatible, non-cytotoxic construction (free of animal-derived materials and acrylamide) and easily withstands CIP/SIP steam sterilization and autoclaving up to 140 °C (284 °F).
Q2: How does the ion trap in the CPS62E protect the sensor?
Answer: The ion trap blocks electrode poisons like hydrogen sulfide ($H_2S$) and heavy metals from reaching the internal $Ag/AgCl$ reference element, preventing reference poisoning and sensor drift.
Q3: Can the Memosens CPS62E be installed in an upside-down position?
Answer: Yes, the pressurized gel reference system allows upside-down installation without risking air bubble formation at the sensing tip.
Q4: How does Memosens 2.0 technology improve maintenance efficiency?
Answer: Memosens 2.0 digitizes data directly in the sensor head, enabling contactless inductive signal transmission immune to moisture, and allows pre-calibration in the lab for quick plug-and-play field replacement.
