Endress + Hauser COS51D Digital oxygen sensor Oxymax for water, wastewater and utilities

Endress + Hauser COS51D digital oxygen sensor E+H

Endress + Hauser COS51D Oxymax is a reliable and highly accurate oxygen sensor for all kinds of water & wastewater applications (including hazardous areas). Digital signal transmission. Storage of the calibration datas in the sensor.

Endress + Hauser COS51D digital oxygen sensor measured value

  • Dissolved oxygen [mg/l, μg/l, ppm, ppb, % SAT or hPa]

Endress + Hauser COS51D digital oxygen sensor measuring range

0.01 to 100 mg/l
0.00 to 1000 % SAT
0 to 2000 hPa

Endress + Hauser COS51D digital oxygen sensor application

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).

Endress + Hauser COS51D digital oxygen sensor advantages are

• 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

Endress + Hauser COS51D digital oxygen sensor process temperature

–5 to 50 ˚C (20 to 120 ˚F)

Endress + Hauser COS51D digital oxygen sensor process pressure

Ambient pressure ... 10 bar (... 145 psi) abs.
