LH-DC18 UV254 Online COD Analyzer

This instrument uses 254nm deep ultraviolet LED, which is small in size and long in life.The 254nm deep ultraviolet beam is absorbed by the organic matter dissolved in the water during the transmission process, and the degree of absorption is proportional to the concentration of organic matter, so that the content of organic pollutants in the sample can be evaluated by measuring the absorbance of the deep ultraviolet beam,The built-in 565nm wavelength light source is used for turbidity compensation, effectively eliminating turbidity interference.
