GH-800 Infrared Spectrophotometric Oil Analyzer

Infrared Spectroscopic Oil Analyzer Basic Principle
When a monochromatic light passes through the solution being measured, its energy is absorbed. The degree of light intensity absorbed 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
