product overview
The total nitrogen online monitoring equipment, certified by the national authoritative method of potassium persulfate ultraviolet spectrophotometer, can quickly determine the content of pollutants in enterprise wastewatertotal nitrogenThe concentration value of the sample is measured using colorimetric method, advanced cold light source, narrowband interference technology, and microcomputer automatic data processing to directly display the concentration value of the sample. The device is equipped with a 7-inch full-color LCD screen and a guided monitoring mode, which reduces learning costs and allows users to easily and quickly operate it.
Detection Principle
Add potassium permanganate solution to the sample, dissolve it at high temperature in an alkaline medium, and measure the absorbance at a specific light source wavelengthtotal nitrogenThe absorbance. Imported cold light sources emit light source signals to sensors, which are processed by processors to directly provide feedback on sample concentration values, displayed in mg/L.
