Overview

Many organic compounds dissolved in water have an absorption effect on ultraviolet light in digital COD sensors. Therefore, by measuring the degree of absorption of these organic compounds by 254nm wavelength ultraviolet light, the content of dissolved organic pollutants in water can be accurately measured. The COD-408 online COD sensor uses two light sources, one ultraviolet light for measuring COD content in water and one reference light for measuring water turbidity. In addition, a specific algorithm is used to compensate for the attenuation of the light path and to some extent eliminate the interference of particulate suspended matter impurities, thereby achieving more stable and reliable measurement. $r $n $r $n Product features: $r $n does not require reagents, no
