Thermal imaging technology is widely used in all areas of human activity. Scientific research, industry, construction, navigation, security and law enforcement agencies, medical examinations, supervision of electrical equipment – this is a completely incomplete list of the use of thermal imagers. In fact, it is much more extensive. Thermal imagers are based on the principle of radiation of heatwaves by objects with a temperature above absolute zero. The thermal imager captures the difference in temperature surfaces and forms a three-dimensional picture of what is happening online. The picture can be color or monochrome, depending on the preference or modification of the device. As a rule, warmer objects correspond to reds, yellows from the warmer spectrum, and cooler ones to blue, purples from the colder part of the color spectrum. In the case of monochrome images, there is a significant difference in color density. Most of the devices communicate with Android, iOS, Windows. Data can be written to built-in media or transferred via Wi-Fi for processing. Thermal imagers are classified according to their application, accuracy, temperature range, size, and portability. All devices are easy to use, intuitive, and use technological developments.
Spheres of usage a non-contact infrared scanner
The infrared scanner is used in metallurgy and mechanical engineering for temperature control. In the construction and audit of buildings, the scanner is used to find leaks of heat, water, refrigerants in cooling systems, identify points of overload in the electrical network, and identify defects in walls, foundations, and roofs. The police, rescuers, widely use it, and the military to detect poor visibility and difficult weather conditions. The thermal imager is used for navigation by ships, unmanned vehicle systems. Widely implemented security cameras for the protection of residential and non-residential premises. Confectioners use a non-contact scanner for making caramel, tempering chocolate. In medicine, it is good for diagnosing disorders of the peripheral circulatory system, thyroid gland, musculoskeletal system, injuries, and detecting tumors in the early stages. During the pandemic, the non-contact infrared scanner became popular for thermometry. It allowed many people to pass the fever test quickly and safely in the shortest possible time.
What do you need to operate using a non-contact infrared scanner? (H2)
To work with a non-contact scanner, you must follow a few simple guidelines. To study the temperature of a person’s body, it is necessary to aim the device at the forehead, wrist, and the area near the lacrimal canal or the middle of the forearm of your choice. The most accurate measurement will be the area near the lacrimal canal. It is necessary to remove interfering hair, headwear, and glasses. The room temperature must be within the comfortable range. Otherwise, it is necessary to adjust the readings. Human skin should be dry, clean, without wet wipes, a thick layer of makeup. The test subject should not be stressed, overheated by physical activity, clothing, or being in a too hot or, on the contrary, cold street. When examining the cold season, remember that the forehead and hands, not covered with clothing, are cooled and will not give the true temperature. Therefore, it makes sense to measure the temperature in the middle of the forearm, usually covered by clothing. The device should rary, cold street. When examining the cold season, remember that the forehead and hands, not covered with clothing, are cooled and will not give the true temperature. Therefore, it makes sense to measure the temperature in the middle of the forearm, usually covered by clothing. The device should be placed 4-6 inches from the skin. Outside this range, the reading will give an error. Some instruments require verification with a so-called reference black body. It is necessary to keep the temperature sensor clean. You can periodically wipe it with alcohol-containing wipes. An important aspect is the current battery charge of the scanner. The room should be free of drafts from an air conditioner or areas of hot air from a heater.
Temperature measurement with a thermal scanner does not require any special qualifications. It’s simple, convenient, comfortable, and safe. The infrared scanner is versatile and can be used almost anywhere, from hospitals to offices and manufacturing. The measurement procedure is hygienic. There is no need to fear infection through the device when used by a large number of people. Many measurements are stored in the device’s memory, which is certainly convenient for the doctor and patient. When used correctly, the meter gives accurate readings. The affordable price makes this device affordable for everyone. It isn’t easy to find an alternative to this research method regarding speed and wide application. Shortly, the field of application of thermal imagers has almost unlimited potential.
