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.
Unbreakable: PEEK sensor body withstands harsh conditions ensuring product safety
Open aperture prevents blocking of the sensor even in media with a high dirt load.
Chemically stable reference gel assures long-term stable measurements
Low maintenance: ISFET technology is insensitive to high temperature or temperature changes which results in long calibration intervals
Maximum process safety: Non-contact, inductive signal transmission eliminates all problems caused by moisture or corrosion.
