DSC500 series COD sensor is a new generation of environmentally friendly COD / TOC sensor launched by Disen Hezhi Electronics, which requires no reagents, no pollution, and is more economical and environmentally friendly. Small size, more convenient installation, and continuous water quality monitoring online. Automatically compensate for turbidity interference, with an automatic cleaning device, even with long-term monitoring, it has excellent stability.
Measurement principle:
Many organic substances dissolved in water have an effect on ultraviolet light. Therefore, the total amount of organic pollutants in water can be measured by measuring the absorption of ultraviolet light at a wavelength of 254 nm by these organic substances. The Y550 series sensor uses two light sources, one 254nm ultraviolet light and one 850nm infrared light, which can automatically compensate for the attenuation of the optical path and the influence of turbidity, thereby achieving more stable and reliable measurement values.
