Water Quality 4-Nitrogen Analyzer | Ammonia, Nitrate, Nitrite, Total N

Ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, and total nitrogen are key indicators for evaluating the degree of water pollution. They mainly detect the concentration indicators of ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, and total nitrogen in water quality, and have intelligent data analysis functions. They are used for the detection of industrial wastewater, urban sewage, domestic sewage, and surface water wastewater in various industries.

Core principle: How to accurately quantify nitrogen content using spectrophotometry?

The water quality four nitrogen detector adopts spectrophotometry as its core technical principle, strictly following relevant national standards and methods to ensure the accuracy and authority of the detection results.

Its testing process is scientifically rigorous:

Sample pretreatment: According to different detection items, use specialized reagents to pretreat the water sample. Total nitrogen detection requires alkaline potassium persulfate digestion to convert various forms of nitrogen into nitrate.

Color reaction: The processed sample reacts with a specific color reagent. If ammonia nitrogen is measured using Nessler's reagent or salicylic acid spectrophotometry, and nitrite is measured using diazo coupling spectrophotometry, the color intensity of the product is directly proportional to the concentration of the analyte.

Precision optical detection: The reaction solution is injected into a precision colorimetric cell, and the instrument is illuminated by an imported ultra-high brightness LED light source. A high-precision optical sensor detects the absorbance value at a specific wavelength.

Intelligent quantitative analysis: The instrument automatically calculates the * * concentration of various nitrogen indicators in the sample based on the Bill Lambert law, through the built-in standard curve and algorithm model.

Result output and storage: The detection results are displayed in real-time on a 10.1-inch touch screen and stored in a large capacity memory.
