Automatic Online Total Nitrogen Detector for Water Quality Monitoring

Online total nitrogen automatic detector is an integrated total nitrogen water quality monitoring system, which can dynamically detect a variety of pollutants for online water quality monitoring in various application.
Potassium persulfate oxidation digestion solution and water sample under high temperature and high pressure, various nitrogen-containing compounds in the water sample are transformed into nitrate through potassium persulfate oxidation digestion. Under acidic conditions, nitrate reacts with chromogenic agent. Finally, it is directly proportional to the nitrogen content in the sample based on the color depth to obtain the total nitrogen content in the sample.
