What is Thermography?

  Infrared thermography is the technology of detecting heat with sensitive, non-contact, non-destructive electronic equipment and converting the infrared energy into a video image. Since infrared energy is a direct and proportional function of temperature, the video-captured image you see is designed to depict different temperature levels.  The thermal image looks very similar to a black and white or a color picture where varying shades of color represent different temperature levels.

 In black and white mode, darker shades of gray correspond with lower temperatures, and lighter shades of gray or white correspond to higher temperatures and sometimes "hot spots."  

In color mode, each shade represents a temperature range—warmer colors indicate higher heat and potential hot spots.
