Benefits
-
Memosens 2.0 offers extended storage of calibration and process data, enabling better trend identification and providing a future-proof basis for predictive maintenance and enhanced IIoT services.
-
The additional platinum electrode enables constant monitoring of reference impedance and is a reliable indicator of the sensor quality.
-
Simultaneous measurement of pH, ORP and rH values (in rH mode) offers a better process overview and allows for a tighter process control.
-
Robust: Large PTFE ring junction and reference with ion trap prevent poisoning of the sensor.
-
Suitable for harsh applications: Process glass for highly alkaline media and pressure-stable up to 17 bar (246 psi).
-
Reduced operating costs: Lab calibration and fast sensor exchange on site minimize process downtime. Sensor regeneration in the laboratory extends the sensor lifetime.
-
Non-contact, digital signal transmission ensures reliable measurements resulting in maximum process safety.
