In fact, two instruments are electronic balances that can be heated. After the sample is put on and weighed, the instrument uses a halogen lamp or infrared heating to remove the water and then weigh. The weight difference between the two is the moisture of the sample. Of course, The instrument can automatically display the proportion of moisture.
Halogen ring light
The ring-shaped halogen lamp ensures that the sample is heated evenly and the operation is simple and accurate. The biggest difference between a halogen ring lamp and an infrared incandescent lamp is that the glass envelope of the halogen lamp is filled with some halogen gas (usually iodine or bromine). Its advantages are clean, no accessories, easy installation, temperature control, etc. . The working principle is: When the filament heats, the tungsten atoms are evaporated and move toward the glass tube wall. When close to the glass tube wall, the tungsten vapor is cooled to about 800°C and combined with the halogen atoms to form the tungsten halide (iodine Tungsten or tungsten bromide). The tungsten halide continues to move toward the center of the glass tube and returns to the oxidized filament. When it is hot, it will re-decompose into halogen vapor and tungsten. The tungsten is then deposited on the filament to make up for the evaporated part. Through this regeneration cycle, the useful life of the filament is not only greatly extended (almost 4 times that of the infrared incandescent lamp).
[About Infrared Quartz Lamp]
Consisting of a fused quartz tube and a radiation element, the infrared lamp is mainly used for focusing heating in industrial heating or drying, such as glass products, metal parts, circuit board packaging, film, etc., as well as other drying, drying, heating, quartz Near-infrared and far-infrared lamps use transparent or translucent quartz glass as the outer casing to produce near-infrared radiation lines or far-infrared radiation lines, which are typical old heating methods. We also use ultraviolet lamps to treat certain skin diseases or Indoors, you can get bronzed skin that is exposed to sunlight. Its disadvantages: Infrared radiation is harmful to the human body, and long-term use will cause harm to the operator's body. In recent years, with the development and revolution of technology, the infrared device system will gradually exit the market stage...
In addition, since the infrared light is focused to a point when it is irradiated, the heating is not uniform, and it is easy to burn the object to be measured at a longer time.
