Onsensor
DSC500 series COD sensor is a new generation of environmentally friendly COD/TOC sensor launched by our company. It requires no reagents, no pollution, and is more economical and environmentally friendly. Small size and easy installation, water quality monitoring is available onomatic compensation for turbidity disturbances, with automatic cleaning, for exnt stability even for long-term monitoring.
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. DS550 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.
