Field of application

Oxymax COS51D is a reliable and highly accurate oxygen sensor for all kinds of water & wastewater applications (including hazardous areas). Designed to be low-maintenance with a long operating life, the sensor offers outstanding value for money. Thanks to Memosens digital technology, the Oxymax COS51D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.

Oxymax COS51D 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

The sensor is suitable for hazardous area use (ATEX, FM, CSA).

Benefits

  • Maximum measurement accuracy

  • Logging of sensor load data for easy traceability

  • Intelligent, self-monitoring sensor

  • Minimum calibration effort thanks to simple air calibration

  • Long maintenance intervals

  • Approved for hazardous area use

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.

  • Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.
