DOG-209FA dissolved oxygen sensor is an improvement on the basis of the previous dissolved oxygen electrode. The diaphragm is changed to a steel grit mesh metal film, which has higher stability and pressure resistance, and can be used in more severe environments. It is also small, suitable for continuous determination of dissolved oxygen in urban sewage treatment, industrial wastewater treatment, aquaculture and environmental monitoring.
