Product Description

Many organic substances dissolved in water can absorb ultraviolet light. Therefore, by measuring the extent of absorption of these organic substances to ultraviolet light at a 254nm wavelength, the content of dissolved organic pollutants in water can be accurately measured. The online COD sensor uses two light sources: one for measuring the COD content in water using ultraviolet light, and one for measuring water turbidity with reference light. Additionally, through specific algorithms, it compensates for the light path attenuation and can eliminate the interference of particulate suspended matter to some extent, thus achieving more stable and reliable measurements.
