Field of application

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.

Oxymax COS61D measures the dissolved oxygen concentration in:

  • Wastewater treatment plants:
    - O2 control in the aeration basin
    - Process water treatment and monitoring

  • Water works:
    - Status monitoring of drinking water (oxygen enrichment, corrosion protection, etc.)
    - Water quality monitoring in rivers, lakes or seas

  • Utilities of all industries:
    - O2 control in the biological treatment
    - Process water treatment and monitoring

  • Fish farming:
    - O2 control for optimum growth conditions

Benefits

  • Minimum maintenance, maximum availability

  • Fast, drift-free measurement for precise aeration control and process monitoring

  • Long-term stability for increased process safety

  • Outstanding performance in all aeration processes (SBR, Anamox, etc.)

  • Chemical-free: no electrolyte handling

Videos

  • The concentration of oxygen dissolved in a liquid can be measured using the amperometric or optical measuring principles. This video shows what it is about and how these measuring principles work.
