Endress Hauser Combined pH/ORP sensor Memosens CPS76E
The Memosens CPS76E is a digital combined pH/ORP sensor from Endress+Hauser, engineered as the heavy-duty specialist for simultaneous pH and ORP measurement in demanding chemical processes and poisoning media. Featuring Memosens 2.0 technology and a unique contamination-resistant reference, it delivers stable measurement in polluted, poisoning media and in media with low conductivity.
Key Features and Benefits
-
Simultaneous pH, ORP, and rH Measurement: The sensor measures pH, ORP, and rH value (in rH mode) simultaneously, providing a better process overview and enabling tighter process control.
-
Unique Ion Trap for Poison Resistance: A unique ion trap prevents poisoning of the electrode’s junction and reference, ensuring a long sensor lifetime even in media with high levels of electrode poisons such as H2S.
-
Contamination-Resistant Reference: The advanced gel technology with ceramic junction and ion trap guarantees stable measurement in polluted, poisoning media and in media with low conductivity.
-
Optional Pressurized Reference: The optional pressurized reference ensures reliable measurement in blocking media, such as dispersions.
-
Memosens 2.0 Digital Technology: Offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services.
-
Maximum Process Safety: Non-contact, inductive signal transmission resists moisture and enables lab calibration, combining maximum process integrity with simple operation.

The Memosens CPS76E is a digital combined pH/ORP sensor from Endress+Hauser, engineered as the heavy-duty specialist for simultaneous pH and ORP measurement in demanding chemical processes and poisoning media. Featuring Memosens 2.0 technology and a unique contamination-resistant reference, it delivers stable measurement in polluted, poisoning media and in media with low conductivity.
The sensor operates on the potentiometric measuring principle using a gel compact electrode with ceramic junction and ion trap. It measures pH, ORP, and rH value simultaneously, providing a better process overview and enabling tighter process control. The unique ion trap prevents poisoning of the electrode’s junction and reference, ensuring a long sensor lifetime even in media with high levels of electrode poisons such as H2S. This contamination-resistant reference guarantees stable measurement in polluted, poisoning media and in media with low conductivity. An optional pressurized reference ensures reliable measurement in blocking media such as dispersions.
The sensor’s ORP measuring range covers –1,500 to 1,500 mV. The pH measuring range is 0 to 14 for Application B and 0 to 12 for Application H. Process temperature range is 0 to 140°C (32 to 284°F), with 140°C for sterilization only and a maximum of 100°C in continuous operation. Process pressure ranges from 0.8 to 14 bar absolute for Application B and 0.8 to 7 bar absolute for Application H.
Memosens 2.0 digital technology offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services. Non-contact, inductive signal transmission resists moisture and enables lab calibration, combining maximum process integrity with simple operation.
The sensor features an integrated NTC 30k temperature sensor for automatic temperature compensation. The shaft is constructed of glass to suit the process, with pH membrane glass available in Type B and Type N, and the ORP element made of platinum. The sensor has a diameter of 12 mm (0.46 inch) and is available in shaft lengths of 120, 225, 360, and 425 mm. It connects via an inductive, digital connection head with Memosens 2.0 technology and is rated IP68 for ingress protection. The sensor holds comprehensive hazardous area approvals including ATEX, IECEx, CSA C/US, NEPSI, Japan Ex, and INMETRO for use in Zone 0, 1, and 2.
