Features
DOG-209FA type oxygen sensor improved from the previously dissolved oxygen
electrode, changediaphragm into a grit mesh metal membrane, with high stability
and stress resistant, can be usedin 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.
