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.
