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 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

• 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
