Dissolved oxygen sensor Oxymax COS61

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 handling
Easy measuring point changeover to optical technology compatible with COS31 and COS41

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 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

Features and specifications

Oxygen

Measuring Principle	Sensor Oxygen
Application	Aeration tank, river monitoring, water treatment, fish farming.
Characteristic	Digital, optical (luminescence) dissolved oxygen measurement. No flow needed - measurement possible in still water.
Measurement range	0mg/l ... 20mg/l 0%SAT ... 200%SAT 0 ... 400hPa
Measuring principle	Oxygen-sensitive molecules (marker) are integrated in an optical active layer (fluorescence layer). The fluorescence layer surface is in contact with the medium. The sensor optics are directed at the back of the fluorescence layer. The sensor optics transmit green light pulses to the fluorescence layer. The markers respond (fluoresce) with red light pulses. The duration and intensity of the response signals depend directly on the oxygen contents or partial pressure.
Design	- Calibration data saved in sensor. High degree of EMC protection.
