- Bioreactors/fermenters: control of culture growthFood & Beverage
- CIP/SIP applications
With ATEX, IECEx, CSA C/US, NEPSI, Japan, INMETRO approvals for use in hazardous areas, zones 0, 1 and 2.
A pharma certificate of compliance with sensor serial number specified is available.
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 sensor's exceptional accuracy and reproducibility help you to keep the pH value in the optimum range for a maximized product yield.
-
A special glass membrane and reference system makes the sensor CIP/SIP and autoclaving resistant (up to 140°C/284°F) offering maximum long-term stability.
The sensor protects your product quality with its certified biocompatibility according to USP class VI, FDA compliance of wetted parts, VO 1935/2004 compliance, no cytotoxicity, bioreactivity or animal-based materials.
Streamline maintenance of CPS61E with the Memobase Plus software that automatically stores and documents all relevant sensor and process data.
Maximum process safety through non-contact, inductive signal transmission
Reduced operating costs thanks to minimized process downtime and extended sensor lifetime.
