Talking about the working principle of infrared moisture meter

Infrared moisture meter is used in all industries that need to measure moisture quickly. It is easy to operate and test accurately. It can display data such as moisture value, sample initial value, final value, measurement time, initial value of temperature, final value, etc., and has the connection function with computer and printer.

The infrared moisture meter works:

The infrared moisture meter works by the principle that water molecules absorb infrared light energy of a specific wavelength.

The probe of the infrared moisture analyzer is equipped with a quartz halogen bulb. The light emitted by the lamp passes through the optical system, resulting in the following two types:

1, the wavelength of the beam: one for the absorption of wavelength, its energy will be required by the detection of substances in the water molecules are strongly absorbed;

2, for the reference wavelength, it is characterized by its energy is not detected by the absorption of water molecules, but other factors (such as measuring distance, material color, etc.) have the same impact on the absorption wavelength.

The infrared beam is irradiated on the surface of the material, and then part of it is reflected back. The energy change before and after absorption of moisture in the substance is accurately measured by the absorption wavelength, and after calculation of a mathematical function, an output signal having a certain proportional relationship with the moisture of the measured substance is obtained. .
