Classifying non-contact infrared thermometers and principles of infrared temperature measurement
The non-contact infrared thermometer includes three series: portable, online, and scanning, and is equipped with various options and computer software. Each series includes various models and specifications. The correct selection of infrared thermometer models is crucial for users in different specifications. Infrared detection technology is a key promotion project of national scientific and technological achievements during the Ninth Five Year Plan period. Infrared detection is an online monitoring (uninterrupted) high-tech detection technology that combines photoelectric imaging technology, computer technology, and image processing technology. By receiving infrared radiation emitted by objects, the thermal image is displayed on a fluorescent screen, accurately judging the temperature distribution on the surface of objects. It has the advantages of accuracy, real-time, and speed. Any object, due to the movement of its own molecules, continuously radiates infrared heat energy outward, forming a certain temperature field on the surface of the object, commonly known as a "thermal image". Infrared diagnostic technology is precisely by absorbing this infrared radiation energy, measuring the surface temperature and temperature field distribution of the equipment, in order to determine the heating situation of the equipment. There are many testing devices that use infrared diagnostic technology, such as infrared thermometers, infrared thermal televisions, infrared thermal imagers, and so on. Devices such as infrared thermal televisions and infrared thermal imagers use thermal imaging technology to transform invisible "thermal images" into visible light images, making the testing effect intuitive and highly sensitive. They can detect subtle changes in the thermal state of the equipment, accurately reflect the internal and external heating conditions of the equipment, have high reliability, and are very effective in discovering equipment hazards.
