Field of application
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.
Oxymax COS61 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 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 handling
Easy measuring point changeover to optical technology compatible with COS31 and COS41
