Measuring principle


Many organic substances dissolved in water absorb ultraviolet light. Therefore, the total amount of organic pollutants in water can be measured by measuring the absorption of these organic substances by ultraviolet light at a wavelength of 254 nm. DSC500 series sensors use two light sources, one 254nm ultraviolet light and one 850nm infrared light, which can automatically compensate the optical path attenuation and turbidity effects, thus achieving more stable and reliable measurement values.
