Brand: Erun environmental protection
Name: Laboratory bench-top nitrite nitrogen (NO2-N) water quality analyzer
Model number:ERUN-ST-YN730
Parameters: nitrite nitrogen (NO2-N)(Spectrophotometer)
The laboratory desktop nitrite (NO2-N) water quality detector ERUN-ST-YN730 is developed, designed and produced by Erun Environmental Protection. Its detection principle is that in acidic media, nitrite ions in water samples react with 4-aminobenzene. The sulfonamide reacts to form a diazonium salt, which is then coupled with naphthylethylenediamine dihydrochloride to form a red dye, which is then measured spectrometrically using the nitrite (NO2-N) water quality detector ERUN-ST-YN730.
