An infrared thermometer is a device that measures temperature from a distance without needing to touch the object. It works by detecting the infrared radiation emitted by an object, which increases with temperature. This makes it useful for quickly checking the temperature of surfaces, like cooking equipment or machinery, without risking burns or damage. These thermometers are commonly used in various fields, including cooking, medical settings, and industrial applications. For example, in healthcare, they can quickly measure a person's body temperature, helping to identify fevers without physical contact. Their ease of use and speed make them a popular choice for many temperature-checking tasks.
