Meet the usage habits of domestic users, is a single parameter measuring instrument developed based on the domestic water quality situation and regulatory requirements Potassium persulfate digestion-Sodium chromophorate spectrophotometric methodStandard R&D Design.Add alkaline persulfate to the water sample to convert nitrogen into nitrate nitrogen. Under strong acidic conditions, nitrate nitrogen reacts with the color reagent to form a brownish yellow complex, and its absorbance is measured at a specific wavelength.The instrument is widely used for environmental monitoring，sewage treatment，Research institutions and colleges and universities.
