Infrared (IR) thermometers have become the preferred tool for diagnostics and inspection where temperature is an indicator. Raytek IR thermometers are valued by professionals in a variety of industries—from industrial maintenance to food service, because they quickly, accurately and safely measure surface temperature! Anywhere that temperature is a factor in process, product quality or diagnostics, a Raytek IR thermometer should be close at hand. IR thermometers are easy to use, and since they do not contact the object being measured, they are the safest way to measure hot, hard-to-reach, or moving parts, while eliminating potential damage and contamination.
