What is Infrared Thermography?
Infrared Thermography is the use of an infrared
imaging and measurement camera to "see" and "measure" thermal energy emitted
from an object. Thermal, or infrared energy, is light that is not visible
because its wavelength is too long to be detected by the human eye; it's the
part of the electromagnetic spectrum that we perceive as heat. Unlike visible
light, in the infrared world, everything with a temperature above absolute zero
emits heat. Even very cold objects, like ice cubes, emit infrared. The higher
the object's temperature, the greater the IR radiation emitted. Infrared allows
us to see what our eyes cannot. Infrared thermography cameras produce images of
invisible infrared or "heat" radiation and provide precise non-contact
temperature measurement capabilities. Infrared is especially useful for noting
temperature variations behind walls. A trained technician can spot problems in
homes ranging from water leaking behind walls, rodent and insect infestations,
mold colonies hidden in wall cavities, missing insulation, and hidden electrical
problems.
