Improved CIP stability in hygienic applications with glass-free pH sensor

The new Memosens ISFET electrode is a non-glass pH sensor for the consistent production of high quality food, without the risk of glass shattering at the high temperatures and contaminating food.

Memosens ISFET electrode for food and life sciences industries

Memosens CPS77D is the digital specialist for hygienic applications with its bacteria-proof reference and contamination-resistant gel, it guarantees stable measurements. The sensor is sterilizable with hot steam, autoclavable and features an unbreakable PEEK shaft assuring highest product safety. In addition, the Memosens digital technology combines maximum process and data integrity with simplicity. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.

The Memosens CPS77D ISFET pH sensor offers improved CIP stability in hygienic applications, producing food of consistently high quality requires the use of modern measuring technology. The use of pH glass sensors, which are commonly deployed for pH measurement, is not beneficial in this case, since breakage can contaminate entire production batches with glass shards. The ISFET pH sensor Memosens CPS77D eliminates the risk of product contamination and can withstand more CIP cycles than any other ISFET sensor ever before.

Top benefits:

  • Unbreakable for highest product safety
  • Certified biocompatibility
  • Suitable for hot steam sterilisation and autoclaving
  • Low maintenance thanks to long calibration intervals
  • Six times higher CIP stability compared to conventional ISFET pH sensors
  • Optional Pharma CoC available
  • Maximum process safety through non-contact inductive signal transmission.

Eliminate the risk of glass breakage

Memosens CPS77D is perfectly suited for pH measurement in hygienic and sterile applications in the food and beverage and life science industries where the use of glass sensors is avoided. The sensor features an unbreakable PEEK shaft and eliminates the risk of product contamination due to glass breakage ensuring high product quality.

Increase plant availability

Memosens CPS77D can outlast at least 25 CIP cycles and has therefore significantly improved CIP stability compared to conventional ISFET sensors. It delivers stable and reproducible measured values, even after sterilisation and autoclaving up to temperatures of 135°C.

Safety by certified hygienic design

The sensor is perfectly equipped to meet the strict demands of hygienic applications. Thanks to its new design with an increased chip surface, it is even easier to clean than its predecessor. It comes with all the usual hygiene approvals for the food and life science industries and is TSE-/BSE-free. Its bacteria-proof reference with contamination-resistant gel guarantees stable measurements. In addition, the sensor offers maximum bacteria tightness thanks to its microporous ceramic diaphragm.
