Product Introduction
COD-water-quality-sensor-01
AMT-COD300
Based on ultraviolet absorption method to analyze COD, turbidity, temperature and other parameters in water. 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, qualitative and quantitative analysis can be performed
Analyze various pollutants, especially suitable for judging changes in water quality composition or concentration. The sensor consists of a light source, spectral analysis, measurement optical path, etc. The light emitted by the light source is split into
Two beams. One beam is the measurement light, which undergoes spectral analysis after being absorbed by the water sample to be tested; the other beam is the reference light, which undergoes spectral analysis directly without passing through the water sample. By measuring the spectral characteristics of the two beams separately, the concentration of each pollutant in the water sample can be calculated.
