TCN-2HK expandable intelligent COD ammonia nitrogen analyzer

The TCN-2HK extensible intelligent COD ammonia nitrogen analyzer features a straightforward design, is dependable and consistent, and can precisely capture and interpret data. Uninterrupted spectrum in the wavelength range of 320-1100nm, COD ammonia nitrogen tester capable of qualitative and quantitative analysis of sample substances in the visible and near-infrared spectral regions; the device can expand more than 40 measurement procedures, including CODcr, ammonia nitrogen, total phosphorus, total nitrogen, residual chlorine, heavy metals, and numerous other testing items.

Principle of COD test: rapid resolution spectrophotometry
Water sample, potassium dichromate solution, silver sulfate solution (silver sulfate as a catalyst can be added more effectively to oxidize straight chain fat
Compound) and concentrated sulfuric acid mixture heated to 165℃, dichroic acid ion oxidation of organic compounds in the solution after the color will change, in the instrument measurement range, the degree of color change and COD concentration in the sample is proportional to, therefore, by spectrophotometry measurement of the degree of color change, you can calculate the concentration of COD in the sample.

Ammonia nitrogen test principle: Nesser's reagent spectrophotometry
Ammonia nitrogen in the form of free ammonia or ammonium ion reacts with Nessler's reagent to produce a reddish brown complex. The absorbance of the complex is proportional to the content of ammonia nitrogen, and the absorbance is measured at the wavelength 420nm.
