Water quality monitoring infrared spectrophotometer oil analyzer

　　Water quality monitoring infrared spectrophotometer oil analyzerBasic principle: When a monochromatic light passes through the measured solution, its energy will be absorbed. The intensity of light absorption is proportional to the concentration of the substance being measured, in accordance with Lambert Beer's law: A=log (1/T)=log (I0/I)=a × b × c
