Benefits
- Robust, low maintenance ORP sensor: Large, dirt-repellent PTFE junction protects from soiling by the medium. Long poison diffusion path prevents poisoning of the electrode reference. 
- Suitable for harsh applications: Gold pin or platinum cap cover the full range of oxidizing or reducing media. Shaft glass ensures high chemical stability. The sensor is pressure stable up to 17 bar (246.5 psi) absolute. 
- Memosens 2.0 technology enables the sensor to store more process and calibration data. It lays the basis for IIoT services and predictive maintenance. 
-  Extremely reliable measurement with to non-contact, inductive signal transmission results in increased process safety. 
- Lab calibration and fast sensor replacement on site allow for minimized process downtimes, reducing operating costs.
