The difference between fast halogen moisture analyzer and infrared moisture analyzer
Halogen moisture detector is a moisture analyzer developed rapidly in recent years. It is mainly used to detect the content of free water on the surface of solid samples. The moisture is volatilized by heating with halogen lamps, and the moisture content in solid samples is directly displayed on the electronic balance. . Through this method and principle, the Halogen Moisture Analyzer can also measure the evaporation residue or heating loss of certain samples.
The predecessor of the halogen rapid moisture analyzer is the infrared rapid moisture analyzer. The main difference between the two is the different heating methods. The heating source of the halogen moisture analyzer is a halogen lamp, and the heating source of the infrared moisture analyzer is a far-infrared dark The field heater, due to the different structure and principle of the heating lamp, also has a certain influence on the test results of the sample. Halogen lamps are the same as our usual fluorescent lamps, the difference is that the halogen gas filled in the lamp tube, through the voltage at both ends, makes the inside of the lamp tube emit light and heat, while the infrared lamp, as the name suggests, is heated by infrared rays.
The advantages of halogen lamps: fast heating speed, uniform heating, it is not easy to decompose the sample during the heating process, while the infrared lamp (spherical) has a slow heating speed due to the structure, during the heating process, the temperature of the middle part will be high, while the edge The temperature of the area is low, that is to say, the heating is uneven, which causes errors in the test results during the test. In addition, some special samples will cause the sample to decompose due to infrared rays, thus affecting the test results. Due to the structural shortcomings of infrared heating, infrared rapid moisture analyzers are basically eliminated in the market now.
Vicomito VM-E series integrates VicoMeito's mature technology in the field of moisture determination to make the whole analysis system more perfect. The high-efficiency drying heater-high-quality ring halogen lamp is used for heating to quickly and uniformly heat the sample; the design of the instrument is intelligent and simple, and the user's one-button measurement function is realized without professional knowledge.
Because different industries have different definitions of moisture, in order to meet the needs of users, VM-E series has a variety of built-in moisture display methods, including but not limited to moisture content, solid content, moisture regain, wood moisture content and other modes, and for For different samples in different industries, the instrument reserves 100 user-defined measurement methods. Users can set the measurement mode according to actual needs, and the custom program is automatically stored. The user's determination requirements for different samples.
