LS4200 Portable Compressed Gas Oil Content Analyzer

Basic Principle

When monochromatic light passes through the measured solution, its energy is absorbed. The degree of light intensity 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.
