Measurement Principle

The measurement principle of shinyei TDLAS T-1 is based on the Lambert-Beer law.
The energy of light is absorbed by water molecules at specific frequencies. When the length of the absorption path and the absorption coefficient are constant, the absorbance is proportinal to the concentration of the water vapor.
Shinyei TDLAS T-1 can sense and indicate moisture level directly by measuring the intensity of the diode laser, which has transmitted through a sample gas, at a photo detector.
