Endress + Hauser Digital pH sensor Memosens CPS171D

Memosens glass electrode for bioreactors and fermenters in the biotech industry

Keep the pH value of your batch in the optimum range and maximize your product yield with Memosens CPS171D. 

Thanks to its rugged design and long-term stability, it provides extremely accurate, reproducible and 

reliable measuring values even after CIP/SIP and autoclaving. 

With the Memosens digital technology, CPS171D combines maximum process and data integrity with simple operation. 

It resists corrosion and moisture, enables lab calibration and simplifies predictive maintenance.

Benefits

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. Approved for hazardous area use.
