Infrared Thermometers

The advanntage of an infrared thermometer's compared to a conventional probe thermometer is speed and the fact that it is non-contact. However, an infrared thermometer only measures the surface temperature. Infrared thermometers are easy to use, simply point the instrument at the object you wish to measure and provide a digital LCD read out of the temperature.
Infrared Explained. Infrared energy is emitted from the surface of all physical objects. This energy is part of the electro magnetic spectrum. Infrared radiation can have a wavelength of a fraction of a micron up to several hundred microns. Infrared thermometers measure infrared with a wavelength throughout the range of 4 and 14 microns.
