- Dispersions
- Precipitation
- Emulsions
Pulp and paper industry

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.

Videos

This video shows how the pH value of a liquid can be determined by the potentiometric measuring principle.
Memosens technology converts measured values into digital signals and transfers them without a contacting connection. This video shows how Memosens improves processes and makes your life easier.
