Infrared thermometers are devices that measure temperature from a distance by detecting the infrared radiation emitted by an object. They are commonly used in various fields, including medicine, cooking, and industrial applications, to quickly and accurately gauge temperature without direct contact. These thermometers work by focusing infrared energy onto a sensor, which converts it into a temperature reading. They are particularly useful for measuring the temperature of moving objects or surfaces that are difficult to reach, making them a convenient tool in both professional and home settings.
