Description
Memosens COS81E hygienic oxygen sensor, 120 mm, is an optical dissolved-oxygen probe engineered for sterile and hygienic process duties from laboratory fermentation through full-scale production. The 12 mm diameter body with 120 mm length and plug-in head connection integrates a PT-1000 temperature sensor for compensated oxygen measurement. Its matched optical measuring system limits ageing of the optical spot, delivering precise, stable readings over extended operating periods and supporting consistent product quality. Digital Memosens 2.0 technology enables extended data storage, automatic sensor identification, and a solid basis for predictive maintenance and efficient plant operation. The sensor is autoclavable up to 135 °C, matching demanding sterilisation regimes in biotech and pharmaceutical environments. Measurable parameter is oxygen; the sensor signal is digital. Offered as a single unit from manufacturer Endress+Hauser under the COS81E® designation, this hygienic oxygen sensor suits fermentation monitoring and other applications where sterility, hygiene, and long-term measurement reliability are essential.
This article is part of Dissolved oxygen & multiparameter meters, in pH & electrochemistry.

Questions about Memosens COS81E hygenic oxygen sensor, 120 mm
What is this article?
Memosens COS81E hygenic oxygen sensor, 120 mm is the article on this page. Luminix Health distributes Endress+Hauser for laboratory use. It sits in Dissolved oxygen & multiparameter meters, inside pH & electrochemistry, in Lab instruments.
A dissolved-oxygen meter reads oxygen in a liquid, optically or with a Clark cell. A multiparameter meter adds pH, conductivity or both on one instrument. The sensor cap or the membrane is the consumable. A reading in air and a reading in water are different calibrations.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
