Optical Dissolved Oxygen Sensor

Product Description


Dissolved oxygen sensor based on the latest polarographic analysis technology, the steel gauze structure of integrated silicone rubber permeable film as a permeable film, which has the advantages of collision resistance, corrosion resistance, high temperature resistance, no deformation, small maintenance and so on.

The electrode body is made of 316L stainless steel, which is corrosion-resistant and more durable. The sea water version can also be plated with titanium, which also performs well under strong corrosion.


It is specially used for measuring PPB dissolved oxygen of boiler feed water and condensate water.
