COD Sensor Opens a New Era of Green Water Quality Monitoring
Analyze COD, turbidity, temperature, and other parameters in water bodies based on ultraviolet absorption method. Organic pollutants primarily absorb in the ultraviolet and visible bands. By scanning and analyzing the absorption spectrum in the 254 nm ultraviolet-visible band, combined with chemical modeling algorithms, various pollutants can be qualitatively and quantitatively analyzed, making it particularly suitable for determining changes in water quality composition or concentration. The sensor consists of a light source, spectral analysis, and measurement optical path, among other components. The light emitted by the light source is split into
