HLNO2-1 typeNitrite nitrogen water qualityOnline monitoring analyzer

Working Principle:In a phosphoric acid medium, nitrite reacts with p-aminobenzenesulfonamide to form diazonium salts, which then react withN - (1-Tea based) - Ethylenediamine Coupling ReactionThe change in color of the mixture is proportional to the nitrite nitrogen content in the water sample, and the nitrite nitrogen value of the water sample can be calculated by colorimetry.
