Everything around us constantly emits infrared energy which is outside the visible spectrum. The wavelength of this infrared energy changes depending on the temperature of the object. An Infrared camera works by measuring these wavelengths and then displaying the temperature of each object on the screen using a color code.
The camera can then be used to find “cold” or “hot” spots which may indicate potential problems. Using an Infrared camera can reveal many hidden problems that often cannot be detected in the course of a traditional visual inspection.
Although Infrared thermal imaging is a far better diagnostic tool than the naked eye, it does not guarantee 100% accuracy, unless removal or destruction of components can be achieved to validate findings. Whenever possible, other tools are used to verify thermal image. Even so, we do not claim to have x-ray vision. Conditions may change and cause the apparent temperatures revealed on thermal images to be different at any given time.
