The Basics of Laser Temperature Guns

Laser guns, also known as infrared thermometers or IR thermometers, are handheld devices that use the principles of infrared radiation to measure the temperature of an object or surface without making physical contact. They work based on the fact that all objects emit infrared radiation, and the intensity of this radiation increases with temperature. When you aim a laser gun at an object, it captures the infrared radiation emitted and calculates the object’s temperature.
