DOG-209FA Industrial Dissolved Oxygen Electrode
Features
DOG-209FA type oxygen electrode 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, maintenance volume is smaller, suitable for urban sewage treatment,
industrial wastewater treatment, aquaculture and environmental monitoring and other fields of
continuous measurement of dissolved oxygen.
