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 monitoringWater works:
- Status monitoring of drinking water (oxygen enrichment, corrosion protection, etc.)
- Water quality monitoring in rivers, lakes or seasUtilities of all industries:
- O2 control in the biological treatment
- Process water treatment and monitoringFish 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
