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 ensures highest product safety where glass breakage is intolerable.
-
With its certified biocompatibility and pharma compliance (optional Pharma CoC), the sensor protects the quality of your products.
The sensor is suitable for hot steam sterilization and autoclaving offering long-term stable measurements.
Low maintenance: ISFET technology is insensitive to temperature variations and shows virtually no acid or alkaline errors, allowing for long calibration intervals.
Six times higher CIP stability compared to conventional ISFET pH sensors ensures a longer lifetime even when the sensor is exposed to cleaning in place.
-
Maximum process safety: Non-contact inductive signal transmission eliminates all problems due to moisture or corrosion.
