Digital oxygen sensor
Oxymax COS61D

Oxymax COS61D is a high-performance, digital oxygen sensor that offers fast, accurate and drift-free measurement. It supports your process with low maintenance, high availability and easy handling. The sensor's long-term stable fluorescence layer is exclusively oxygen-selective (interference-free), ensuring consistently reliable measurement. Thanks to Memosens digital technology, the Oxymax COS61D combines maximum process and data integrity, and facilitates simple lab calibration.

Measuring / Application task
  • Measuring principle

    Optical oxygen measurement

  • Application

    Aeration tank, river monitoring, water treatment, fish farming

  • Characteristic

    Digital, optical measurement of dissolved oxygen based on fluorescence quenching
    Measurement possible in still water

  • Measuring range

    0 to 20 mg/l
    0 to 200 %SAT

  • Measuring principle

    Oxygen-sensitive molecules (marker) are integrated in an optical active layer (fluorescence layer). The fluorescence layer surface is in contact with the medium. The sensor optics are directed at the back of the fluorescence layer. The sensor optics transmit green light pulses to the fluorescence layer. The markers respond (fluoresce) with red light pulses. The duration and intensity of the response signals depend directly on the oxygen contents or partial pressure.
