SH-21A infrared oil analyzer

1SH-21A infrared oil analyzerBasic Principles

When a monochromatic light passes through the measured solution, its energy will be absorbed. The strength of light absorption and the measured intensity;

The concentration of a substance is proportional and follows Lambert Beer's law: A=log (1/T)=log (I0/I)=a × b × c.
