YCH305 self-cleaning COD sensor based on the principle of ultraviolet absorption method, by measuring the absorption degree of these organic compounds to 254nm wavelength ultraviolet light, can accurately measure the content of dissolved organic pollutants in water. One turbidity detection light source is integrated in the interior, and the turbidity interference of the measured water is automatically compensated. With automatic cleaning brush device, even long-term monitoring still has excellent stability.

Product Features

✅No reagents, no pollution, more economical and environmentally friendly.

✅Can measure parameters such as COD, BOD,TSS and temperature.

✅Automatically compensate for turbidity interference.

✅With automatic cleaning brush to prevent biological attachment and longer maintenance cycle.
