1. The ammonia nitrogen analyzer adopts the national standard: salicylic acid colorimetric method for measuring ammonia nitrogen in water quality. It uses sodium dichloroisotricyanate, as specified by international standards, instead of the commonly used sodium hypochlorite, greatly enhancing the stability and effectiveness of the reagent solution (Type B).
2. The ammonia nitrogen analyzer can generate and store standard colorimetric curves, and can adjust the colorimetric curves for ammonia nitrogen in different water bodies.
3. The ammonia nitrogen analyzer employs a unique optical path colorimetric system, significantly improving the instrument's reliability and stability.
4. A unique sample processing method shortens the analysis time while ensuring accurate analytical results (Type B).
