The monitoring instrument complies with the national standard "HJ/T 102-2003 Technical Requirements for Total Nitrogen Water Quality Automatic Analyzer" and the operation manual "HJC-ZY98-2022 Water Quality Total Nitrogen Online Monitoring Instrument Testing Operation Manual" issued by the Environmental Monitoring Instrument Quality Supervision and Inspection Center of the Ministry of Environmental Protection. It can work continuously and automatically without human supervision for a long time according to on-site settings, and is suitable for water quality monitoring of pollution source discharge wastewater, municipal sewage treatment plant wastewater, surface water, etc.

In the presence of potassium persulfate, nitrogen-containing compounds in the water sample undergo high digestion and are completely converted into nitrate nitrogen. After cooling to room temperature, they react with the indicator to form a colored complex. The monitor detects this color change and converts it into the total nitrogen value output.
