GAOTek Aquarium Water Detecting Nitrite Ion Meter

GAOTek aquarium water detecting nitrite ion meter 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.
