Digital oxygen sensor
Oxymax COS51D ©Endress+Hauser

The concentration of oxygen dissolved in a liquid can be measured using the amperometric or optical measuring principles. This video shows what it is about and how these measuring principles work.

Memosens converts the measured value to a digital signal and transfers it to the transmitter without a contacting connection. This video shows how Memosens optimizes process control and maintenance.

Memosens amperometric oxygen sensor for water, wastewater and utilities

Oxymax COS51D is a reliable and highly accurate oxygen sensor for all kinds of water & wastewater applications (including hazardous areas). Designed to be low-maintenance with a long operating life, the sensor offers outstanding value for money. Thanks to Memosens digital technology, the Oxymax COS51D combines maximum process and data integrity with simple operation. It resists corrosion and moisture, enables lab calibration and facilitates predictive maintenance.
