This product adopts N-(1-naphthalene) ethylenediamine dihydrochloride spectrophotometric method to detect nitrite nitrogen. A purple-red complex is formed in the environment of ℃, and the color of the solution is proportional to the content of nitrite nitrogen in the sample. The instrument determines the content of nitrite nitrogen in the water sample by photoelectric calorimetry.
