Endress+Hauser Conducta

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 samplesLarge dirt-repellent PTFE-junction to avoid cloggingElectrode is durable and maintenance-free as the sensors are gel-filledLarge measuring range up to 135 °CAutomatic temperature compensation thanks to integrated NTC 30kΩ temperature sensorWith Ag/AgCl reference systemSupports quality management requirements with tamper-proof data storage including serial number and calibration historyThe sensor is supplied pre-calibrated and ready for immediate use.

Endress+Hauser Conducta

pH electrode CPL57E

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 measurementsLarge dirt-repellent PTFE-junction to avoid cloggingElectrode is durable and maintenance-free as the sensors are gel-filledAutomatic temperature compensation thanks to integrated NTC 30kΩ temperature sensorWith Ag/AgCl reference systemSupports quality management requirements with tamper-proof data storage including serial number and calibration historyThe sensor is supplied pre-calibrated and ready for immediate use.
