Special Parameter Online Monitoring Instrument
Nitrate Nitrogen Online Analyzer
product details

Product Model: NO3N-8000


Measurement Principle


The water sample is injected into the reaction tank through the injection pump, and then the pH value of the solution is adjusted, and finally the characteristic color developer is added to carry out the color reaction under acidic conditions, and the colorimetric determination is carried out under a certain wavelength, and then the nitrate nitrogen content in the water sample is calculated according to the Lambert-Beer law.


Typical Applications


Automatic analysis and monitoring of nitrate nitrogen content in surface water, domestic sewage and industrial wastewater.
