This is COD & BOD (COD UV351H)-(MTI.WQMS.DRFN.CODBOD). With this, the total amount of organic pollutants in the water can be measured by measuring the degree of absorption of these organic substances to 254nm wavelength ultraviolet light. The COD 351 digital sensor adopts two light sources, one 254nmultraviolet light, and one turbidity compensation, which can automatically eliminate the interference of suspended substances in the water, so as to achieve more stable.
