Here is why in reverse order of importance. V Differences in Accuracy of Different Types of Infrared Thermometers 5.1 Three Categories of Infrared Thermometers. Research has shown that the infrared digital non-contact thermometers are reliable, convenient and accurate alternatives for measurement of temperature. In 2020 when COVID-19 pandemic hit the world, infrared thermometers were used to provide safe and accurate testing. Touchless infrared thermometer are not as accurate measuring core body temperature as other means like an ear, oral or rectal thermometer. But the temperature readings vary depending on which one you use, and you need an accurate body temperature to determine if a fever is present. Learn about the benefits and the proper use for accurate results. They are hugely popular and useful for screening of fever in the paediatric (children) population as well. The non-contact infrared thermometer is a reliable, comfortable and accurate option for measurement of temperature and is very useful for the screening of fever in the paediatric population. How does an Infrared Thermometer work? Are Infrared Thermometers Accurate? You can take a temperature using the mouth (oral), armpit (axillary), or ear (tympanic). [citation needed] Public health authorities such as the FDA in United States published rules to assure accuracy and consistency among the infrared thermometers. According to different uses and accuracy, infrared thermometers can be roughly divided into medical-grade infrared thermometers, consumer-grade infrared thermometers, and industrial-grade infrared thermometers. Most accurate way to take temperature in adults. For professional use, the Fluke 62 MAX Plus is one of the best infrared thermometers because it is an accurate and robust all-rounder with a broad measuring range, a 12:1 D:S ratio, adjustable emissivity settings, and dual lasers to help you pinpoint the edges of the measurement area. Non-contact infrared thermometers are medical devices. More studies are recommended to support the evidence found in this study and compare its accuracy with more c … For example, if an infrared thermometer is used, a reading of between 36 and 37.4 degrees Celsius is deemed normal; anything higher than that indicates a fever.
