TCNPN-4HK Expandable Intelligent COD Ammonia Nitrogen Total Phosphorus Total Nitrogen Analyzer

TCNPN-4HK extensible smart COD ammonia nitrogen total phosphorus total nitrogen analyzer possesses uncomplicated framework, dependable and consistent, and precise measurement. Uninterrupted range of wavelengths from 320-1100nm, COD ammonia nitrogen total phosphorus total nitrogen tester able to perform qualitative and quantitative examination of sample materials in the visible and near-infrared spectral zones; the device can broaden over 40 measurement protocols, encompassing CODcr, ammonia nitrogen, total phosphorus, total nitrogen, residual chlorine, heavy metals, and numerous other examination components.

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.
