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.

Optical oxygen sensor for water, wastewater and utilities

Oxymax COS61 is a high-performance 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.

  • Benefits

    • Minimum maintenance, maximum availability

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

    • Long-term stability for increased process safety

    • High-performing in all aeration processes (SBR, Anamox, etc.)

    • Chemical-free: no electrolyte...

  • Field of application

    Oxymax COS61 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...
