TCODCr-1HK expandable intelligent COD analyzer

TCODCr-1HK expandable intelligent COD analyzer

The TCODCr-1HK extensible intelligent COD measuring device is uncomplicated in design, dependable and consistent, and provides precise readings. Uninterrupted spectrum in the wavelength range of 320-1100nm, COD tester capable of qualitative and quantitative analysis of sample substances in the visible and near-infrared spectral regions; the instrument can expand more than 60 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.
