Industrial dissolved oxygen electrode DOG-209FA

Model : DOG-209FA

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