Nitrate Nitrogen Water Quality Online Analyzer(NO2N)

Principle of instrument measurement: The water sample to be tested is pretreated. Under acidic conditions, nitrite nitrogen reacts with sulfanilic acid to form a diazonium salt, which is then coupled with N-(1-naphthyl)ethylenediamine hydrochloride to form a red dye. The absorbance is measured by a spectrophotometer to calculate the concentration of nitrite nitrogen.
