DOG-209FA Aquaculture DO probe

dissolved oxygen sensor

Features :

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.
