Memosens CPS171D measures pH in:

  • Biotech and pharma industries
    - Bioreactors/fermenters: process control in enzyme production
    - Bioreactors/fermenters: control of culture growth

  • Food & 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.

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.

Videos

  • 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.
