Infrared Thermometers measure temperature from a distance. This distance can be many miles or a fraction of an inch. Infrared Thermometers are often used in circumstances when other sorts of Thermometers are not practical. If an object is very fragile or dangerous to be near, for example, an Infrared Thermometer is a good way to get a Temperature from a safe distance. Infrared Thermometers work based on a phenomenon called black body radiation. Anything at a Temperature above absolute zero has molecules inside of it moving around.
