Digital infrared (IR) thermometers are designed to measure temperature from a distance by absorbing radiation emitted from the body of the object. The use of a laser additionally allows a beam to be pointed at a specific area of the object. IR thermometers are useful in cases where thermocouple or other probe type sensors cannot be used or do not produce accurate results.

Digital IR thermometers work well in industrial applications such as testing for hot spots, leakages and other fluctuating temperature issues. They are also ideal for measuring hot surfaces or items that should not be touched because of contamination possibility. They are lightweight, compact and easy to use, offering extremely fast response time.
