Water Quality COD Sensor
AMT-COD300 analyzes COD, turbidity, temperature and other parameters in water based on ultraviolet absorption method. Organic pollutants mainly absorb in the ultraviolet and visible bands. By scanning and analyzing the absorption spectrum of the 254nm ultraviolet-visible band, combined with chemical modeling algorithms, various pollutants can be qualitatively and quantitatively analyzed, especially suitable for judging changes in water quality composition or concentration. The sensor consists of a light source, spectral analysis, and measurement optical path. The light emitted by the light source is split into two beams. One beam is the measurement light, which is spectrally analyzed after absorption by the water sample; the other beam is the reference light, which is directly spectrally analyzed without passing through the water sample.
