The COD, ammonia nitrogen, total phosphorus, and total nitrogen analyzer for water quality is developed and designed based on the standards of HJ/T399-2007 "Determination of Chemical Oxygen Demand in Water Quality - Rapid Digestion Spectrometric Method", HJ535-2009 "Determination of Ammonia Nitrogen in Water Quality - Nessler's Reagent Spectrometric Method", HJ671-2013 "Determination of Total Phosphorus in Water Quality - Ammonium Molybdate Spectrometric Method", and "Alkaline Persulfate Digestion Spectrometric Method". This instrument is widely used due to its fast detection, simple operation, and low cost

In terms of emergency monitoring, sewage treatment, chemical, pharmaceutical, hospital wastewater, food and other industries' wastewater testing. Dual wavelength measurement makes detection more accurate, and the digestion colorimetric integrated tube makes detection simpler and safer.

The instrument has the characteristics of small size, light weight, and built-in rechargeable power supply. It is not only used for wastewater detection in various industries, but also for wastewater research in scientific research institutions, universities, and other institutions.

The determination of COD adopts the closed catalytic digestion colorimetric method with a digestion tube, the determination of ammonia nitrogen adopts the Nessler's reagent colorimetric method, the determination of total phosphorus adopts the closed digestion colorimetric method, and the determination of total nitrogen adopts the alkaline persulfate digestion photometric method. After processing the data with a cold light source, narrowband interference technology, and microcomputer, the COD, ammonia nitrogen, total phosphorus, and total nitrogen values of the sample are directly displayed.
