Classifying non-contact infrared thermometers and infrared temperature measuring principle
Non-contact infrared thermometers include three series: portable, online and scanning, and are equipped with various options and computer software. Each series has various models and specifications. Among various types of thermometers with different specifications, it is very important for users to correctly select the model of infrared thermometer. Infrared detection technology is a key promotion project of national scientific and technological achievements in the "Ninth Five-Year Plan". Infrared detection is a kind of online monitoring ( Non-stop) high-tech detection technology, which integrates photoelectric imaging technology, computer technology, and image processing technology. By receiving infrared rays (infrared radiation) emitted by the object, its thermal image is displayed on the fluorescent screen, thereby accurately judging the surface quality of the object. Temperature distribution has the advantages of accuracy, real-time and speed. Any object constantly radiates infrared heat energy due to the movement of its own molecules, thus forming a certain temperature field on the surface of the object, commonly known as "thermal image". Infrared diagnostic technology absorbs this infrared radiation energy and measures the temperature and temperature field distribution on the surface of the equipment to determine the heating condition of the equipment. There are many test equipments that apply infrared diagnostic technology, such as infrared thermometers, infrared thermal TVs, infrared thermal imaging cameras, etc. Equipment such as infrared thermal TVs and infrared thermal imaging cameras use thermal imaging technology to convert this invisible "thermal image" into a visible light image, making the test effect intuitive and highly sensitive. It can detect subtle thermal state changes of the equipment and accurately reflect The heating conditions inside and outside the equipment are highly reliable and very effective in discovering hidden dangers in the equipment.
