Digital optical oxygen sensor Memosens COS81E

Endress + Hauser

Memosens COS81E is the ideal optical oxygen sensor for hygienic applications. Its well-tuned measuring system prevents ageing of the optical spot and offers precise, long-term stable measurements for high product quality. With Memosens 2.0 digital technology, COS81E offers extended data storage providing the perfect basis for predictive maintenance and efficient operation.

Memosens COS81E measures oxygen in applications with high demands to sterility and hygiene such as fermentation processes, from lab to process.

Features and benefits:

  • Designed according to EHEDG and ASME BPE – it avoids cross-contamination and is fully compliant to USP class VI and FDA as well as all GMP and GLP requirements.
  • High process up-time - precalibrate the sensor in your lab and then swap it into your process with plug & play. It does not need polarization time and is immediately ready to measure.
  • Reliable measurement – a built-in reference LED compensates for the aging of the measuring LED. This ensures precise measured values even after frequent CIP/SIP and autoclaving.
  • Reducing maintenance effort – Memosens COS81E does not have a difficult-to-handle electrolyte or sensitive membrane. The sensor cap can be easily exchanged to perform calibration.
  • Versatile sensor application – it can be used in process applications as well as benchtop fermenters.edic
  • Extended storage of calibration and process data – enables better trend identification and provides a future-proof basis for predictive maintenance and enhanced IIoT services

The maintenance kit COV81 is also available. It contains an optical cap, O-rings and further material for the maintenance purpose.
