pH electrode CPL59E Type CPL59E

pH electrode CPL59E
Rugged pH glass electrode with Memosens technology. The ion trap offers a high stability against oxidizing agents and protects the sensor and the junction from drift and inaccurate measurements. The electrode is therefore suitable for measurements in harsh conditions in the chemical and process industry. 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 aggressive media and challenging samples
-Large dirt-repellent PTFE-junction to avoid clogging
-Electrode is durable and maintenance-free as the sensors are gel-filled
-Large measuring range up to 135 °C
-Automatic temperature compensation thanks to integrated NTC 30kW 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.
