Endress + Hauser Digital oxygen sensor Oxymax COS61D -AAA1B3

Memosens optical oxygen sensor for water, wastewater and utilities

Oxymax COS61D is a high-performance, digital 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. 

Thanks to Memosens digital technology, the Oxymax COS61D combines maximum process and data integrity, 

and facilitates simple lab calibration.

Benefits
