- Bioreactors/fermenters: control of culture growthFood & Beverages
- CIP/SIP applications
With its international explosion protection approvals, such as ATEX and IECEx, the digital sensor is suitable for hazardous area use.
A pharma certificate of compliance with sensor serial number specified is available.
Edut
The sensor's exceptional accuracy, reproducibility and reliability helps you to keep the pH value in the optimum range for a maximized product yield.
A specialized glass membrane and reference system makes the sensor CIP/SIP and autoclaving resistant (up to 140°C/284°F) offering maximum long-term stability.
Thanks to the Memosens technology, the cable connection cannot be affected by moisture or corrosion: you can count on the sensor's highest availability and your batch is safe.
The sensor protects your product quality with its certified biocompatibility according to USP class VI, FDA compliance of wetted parts, no cytotoxicity, bioreactivity or animal-based materials.
The sensor provides you with process and sensor data that allows you to decide if the sensor is ready for the next batch or should be replaced - a big improvement for your product safety.
Streamline maintenance of CPS171D with the Memobase Plus software that automatically stores and documents all relevant sensor and process data.

Videot
-
The pH value of a liquid can be calculated using the potentiometric measurement principle. This video shows what it is about and how this measuring principle works.
-
Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
