Compact ORP Measurement for Harsh Processes

The CPF82E is designed for ORP measurement where the process conditions are more demanding than standard water applications. It is particularly suited to industrial water and wastewater treatment, mining, minerals and metal processing.

The integrated assembly keeps the measuring point compact while providing a straightforward installation with an NPT 3/4" process connection.

Robust Reference System

The CPF82E uses a gel-filled compact electrode with a double-chamber reference system, potassium nitrate bridge electrolyte and a PTFE diaphragm. The platinum ring serves as the ORP measuring electrode.

The large, dirt-repellent PTFE junction helps reduce maintenance requirements in applications where contamination can affect conventional electrodes.

Memosens 2.0 Digital Technology

With Memosens 2.0, measurement data is transferred digitally between the sensor and transmitter. The sensor can also store calibration and process information, making it possible to calibrate the sensor away from the measuring point and then install it back into the process.

This is especially useful when sensor replacement and maintenance need to be handled efficiently.

Designed for Mining and Wastewater

The CPF82E is intended for demanding applications including neutralization, flotation, leaching and inlet/outlet monitoring. Its compact construction and resistance to contamination make it suitable for process environments where conventional ORP sensors may require frequent maintenance.
