Description
Moisture content is an important and decisive quality parameter in many industrial production processes. Different production links have different requirements for moisture content. Moisture changes during the production process not only affect the quality of the product, but also affect the production efficiency of the factory.
QL-300 online moisture analyzer provides online moisture analysis, which can perform instant, non-contact measurement of products and raw materials, helping to control moisture changes in products during the production process so that the production process can be adjusted in a timely manner. The QL-300 online moisture meter can not only help companies improve production efficiency, but also help companies reduce waste and save resources.
Working Principle
Hydrogen-oxygen bonds in water molecules absorb near-infrared rays of specific wavelengths. At a specific wavelength, the reflected near-infrared energy is inversely proportional to the near-infrared energy absorbed by the water molecules in the material, so the moisture content of the measured material can be calculated according to the amount of energy loss.
When a water molecule is excited by a specific energy band, it becomes a vibrational state. In the near-infrared part of the spectrum, which is particularly reactive to water molecules, it will be easier for the instrument to transmit, filter and receive energy.
Near-infrared measurement technology is a non-destructive, non-contact real-time measurement technology.
