pH electrode CPL57E / Endress+Hauser Conducta

The pH glass electrode with Memosens technology contains a reference system with salt storage for drift-free measurement at low conductivities. The electrode is therefore suitable for measurements in media with low conductivity, such as boiler feed water, pure, and ultrapure water. Memosens technology is based on true Plug & Play for minimised downtime. Measured values, calibration data, and history are stored directly in the sensor. Memosens offers absolutely secure data transmission and thus ensures increased availability of the measuring point and trouble-free processes. In addition, the inductive Memosens coupling is insensitive to moisture and corrosion.


-Ideal for pure and ultrapure water measurements
-Large dirt-repellent PTFE-junction to avoid clogging
-Electrode is durable and maintenance-free as the sensors are gel-filled
-Automatic temperature compensation thanks to integrated NTC 30kΩ temperature sensor
-With Ag/AgCl reference system
-Supports quality management requirements with tamper-proof data storage including serial number and calibration history


The sensor is supplied pre-calibrated and ready for immediate use.
