Principle
The instrument is based on the principle of Spectrophotometric method, spec-trophotometry, and detects the Absorbance of each water sample at a specific light source wavelength through imported cold light source and narrow-band interference technology. After the data is automatically processed by the microcomputer, the COD and ammonia nitrogen concentration values of the sample are directly displayed. COD detection adopts rapid digestion Spectrophotometric method, spec-trophotometry, and ammonia nitrogen detection adopts Noll's reagent Spectrophotometric method, spec-trophotometry.
Applications
Emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing and other industries wastewater testing, R & D institutions, wastewater research in colleges and universities
