Meet the usage habits of domestic usersIt is a single parameter measuring instrument developed based on the domestic water quality situation and regulatory requirements. It is designed and developed according to the HJ535-20009 "Water Quality - Determination of Ammonia Nitrogen - Nessler's Reagent Spectrophotometer" standard. Ammonia nitrogen in the form of free ammonia or ammonium ions reacts with Nessler's reagent to form a light yellow brown complex. The absorbance of the complex is proportional to the ammonia nitrogen content, and the ammonia nitrogen content (mg/L) is directly displayed after calculation by a microcomputer chip using colorimetric method.
