Near-infrared moisture meter is an instrument widely used in agriculture, food processing, pharmaceuticals and other fields. It is used to quickly and non-destructively measure the moisture content in a substance. It is based on near-infrared spectroscopy, which uses the interaction of substance molecules with near-infrared light to achieve accurate measurement of moisture content.
The main components of the NIR moisture meter are the NIR probe and the host display.
Near-infrared probe: imported light-guided PBS detector, the detector is independently packaged, and the external light does not interfere with the reference measurementThe reference light of the optical path structure and the product measurement light use the same optical path to eliminate the influence of detection error.
Host display: touch screen operation, using precision sampling chip, the host has both analog and digital outputs: RS485 (modbus-rtu standard protocol can be selected), DC 4-20mA
The principle of NIR moisture meter is based on the interaction of NIR light at the molecular level. Near-infrared light transmittance is strong and can penetrate the surface of the material, vibrate and absorb water molecules. The vibrational and absorption properties of water molecules have distinct peaks in the near-infrared spectrum, which are related to the moisture content in the sample.
The advantages of NIR moisture meters are that they are fast, non-destructive, and accurate. Compared to traditional moisture measurement methods such as weighing and drying, NIR moisture meters do not require destructive processing of the sample and can be measured in seconds. This makes its application on the production line very convenient and efficient.
In short, the NIR moisture meter realizes the rapid and accurate determination of the moisture content of the material through the NIR spectroscopy technology. NIR moisture analyzers have a wide range of applications and are of great significance for moisture detection and quality control in agriculture, food processing, pharmaceuticals and other fields. In practical applications, NIR moisture analyzers can improve production efficiency, reduce labor costs, and ensure product quality and safety.
