1. DOG-208F dissolved oxygen electrode applies polarographic principle

2. Use platinum (Pt) as cathode and Ag/AgCl as anode

3. The electrolyte is 0.1M potassium chloride (KCl)

4. Use American imported silicone rubber permeable membrane as breathable membrane

5. It has silicone rubber and steel gauze

6. Collision resistance, corrosion resistance, high temperature resistance and non-deformation performance

It is used in places with trace oxygen content such as thermal power plants, power plants and power stations desalinated water, boiler feed water
