Total Nitrogen Water Quality Online Monitor

  • Description:Method Principle: It involves the conversion of nitrogen-containing compounds in the sample into nitrate by an alkaline potassium persulfate solution at 120-124℃. The absorbances at wavelengths of 220nm and 275nm, denoted as A220 and A275 respectively, are measured using ultraviolet spectrophotometry. The total nitrogen content (expressed as N) is proportional to the corrected absorbance A, which is calculated using a specific formula.

● The instrument is miniaturized and highly integrated, with a size only slightly larger than a computer mainframe, making it easy to transport and install

● Platform and modular design, easy to maintain and quickly repair, more than 95% of the modules are universal

● The entire piping system is made of corrosion-resistant materials and is designed for forward maintenance, which reduces the failure rate, maintenance requirements and extends the service life

● Accurate micro-dosing ensures low reagent consumption and saves operating costs

● Low reagent consumption, reagent level monitoring and early warning, overall reagent replacement, prompt customer notification for easy reagent replacement

● Networked quality control function, remote standard sample verification, remote monitoring of instrument status and remote online software upgrades

● Automatic/manual/network remote measurement, cleaning and calibration

● Fault alarm, reagent level warning, power-on self-check, power-off protection

● Support 4-20mA, RS232, RS485 communication interfaces and MODBUS communication methods

● Imported touch screen, Chinese interface display, and complete user rights management


● Online monitoring of surface water (rivers, lakes)

● Online monitoring of drinking water (drinking water sources, tap water, and groundwater)

● Online monitoring of industrial wastewater is applicable in industries such as pharmaceuticals, petrochemicals, papermaking, textiles, chemicals, food, and wastewater treatment

● Online monitoring of domestic sewage
