COD sensor accuracy ±5% F.S., resolution 0.1mg/L - Do you really understand these parameters?
COD sensor accuracy ±5% F.S., resolution 0.1 mg/L—do you really understand these parameters? It analyzes parameters such as COD, turbidity, and temperature in water based on ultraviolet absorption method. Organic pollutants mainly absorb in the ultraviolet and visible bands. By scanning and analyzing the absorption spectrum in the 254 nm UV-visible band, combined with chemical modeling algorithms, various pollutants can be qualitatively and quantitatively analyzed, making it 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 enters after being absorbed by the water sample to be tested.
