Working principle of Nitrite Sensor N50
The reference electrode silver/silver chloride electrode is encapsulated in a closed electrolyte cavity. The working electrode gold electrode is directly in contact with the solution to be tested.NO2- in solution is oxidized directly on the surface of the working electrode to form a current, which is proportional to the content of NO2- in solution.
