About the measurement principle of the CRDS moisture meter.
CRDS moisture meter Principle of the Tiger Optics series
Laser light is directed into a stainless steel cavity equipped with high-reflectivity mirrors at both ends. The light then bounces back and forth, traveling hundreds of kilometers in less than one millisecond. After raising the light to a predetermined threshold, the light is cut off, and the time it takes for the light intensity to disappear (ring-down) is measured. Since the time is inversely proportional to the presence of molecules in the sample, the moisture content is read from this. Moisture content is detected from the difference in time between Tzero and Tpeak on the created graph. For more details on the principles of the CRDS moisture meter, please refer to the URL below.
