Product Description

Sewage Dissolved Oxygen Electrode (DOG-209FA)


DOG-209FA type oxygen sensor improved from the previously dissolved oxygen electrode,
change diaphragm into a grit mesh metal membrane, with high stability and stress resistant,
can be used in a more harsh environment, maintain volume is smaller, suitable for urban
sewage treatment, industrial wastewater treatment, aquaculture and environmental monitoring
and other fields of continuous measurement of dissolved oxygen.
