E+H Memosens CPS96E Digital pH/ORP Sensor

High-Performance pH & ORP Measurement in Severely Contaminated Media

Accurate pH and Oxidation-Reduction Potential (ORP) tracking in industrial wastewater, chemical slurries, and solids-laden liquids is vital for process control and environmental compliance. Traditional glass electrodes often fail prematurely due to junction clogging, diaphragm poisoning, or moisture ingress at cable connections. The Endress+Hauser Memosens CPS96E Digital pH/ORP Sensor provides a reliable analytical solution specifically designed to overcome clogging and signal loss in severe process environments.

Clogging-Resistant Open Junction & Solid Gel Reference System

The core engineering highlight of the Memosens CPS96E is its specialized open junction design combined with a stabilized solid gel reference electrolyte. Unlike standard ceramic diaphragms that easily clog in media containing high suspended solids, emulsions, or sticky polymers, the open junction maintains direct, unobstructed contact between the process liquid and the reference system.

This design prevents electrolyte poisoning and blockage caused by sulfides, heavy metals, or fats. The robust glass shaft resists chemical attack across extreme pH ranges (0 to 14 pH) and withstands operating temperatures up to +110 °C (+230 °F).

Memosens 2.0 Inductive Technology & Predictive Maintenance

Equipped with Endress+Hauser’s advanced Memosens 2.0 digital technology, the CPS96E converts analog signals directly inside the sensor head into secure digital data packets. Digital signal transmission via contactless inductive coupling eliminates corrosion, humidity interference, and signal distortion caused by wet field cabling.

Memosens 2.0 stores calibration data, total operating hours, process temperature history, and sensor load cycles directly inside the sensor memory head. This enables lab-based pre-calibration under controlled clean conditions, allowing operators to perform quick field sensor swaps in minutes without recalibrating on-site.

Paired with Liquiline transmitters (such as CM44 or CM14), the CPS96E supports predictive maintenance diagnostics, alerting operators to electrode wear before process performance is impacted.

FAQ

Q1: Is the Endress+Hauser Memosens CPS96E supplied as an authentic original unit? A: Yes. We supply 100% genuine, brand-new Endress+Hauser instruments complete with original factory serial numbers, calibration reports, and official documentation.

Q2: What is the main advantage of the open junction on the CPS96E over standard ceramic diaphragms? A: The open junction prevents clogging and blockage in media with high suspended solids, fats, oils, and fibers. It provides direct contact between the reference gel and process liquid without a porous diaphragm that can become fouled.

Q3: Can I calibrate the Memosens CPS96E sensor in a laboratory before installing it in the field? A: Yes. Thanks to Memosens 2.0 technology, calibration data is stored directly in the digital sensor head. Sensors can be calibrated in a clean laboratory environment and quickly swapped in the field without on-site re-calibration.

Q4: How can I request distributor quotes and confirm delivery lead times? A: Simply submit your required E+H model ordering code, immersion length, process media details, and transmitter configuration through our inquiry form. Our sales team will provide a prompt, competitive quotation and export delivery timeline.
