GH-800 Infrared Spectrophotometric Oil Analyzer
Basic Principles
When a monochromatic light passes through the solution being tested, its energy is absorbed. The intensity of light absorbed is proportional to the concentration of the substance being tested, in accordance with Lambert-Beer's Law: A=log(1/T)=log(I0/I)=a×b×c
