DOG-209FA Industrial Dissolved Oxygen Sensor
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.
