Thermography is a non-destructive testing method that uses infrared cameras to detect and measure the thermal energy emitted from an object. This energy is then used to create an image of the object, which can be used to identify potential problem areas. Thermography can be used to detect problems in electrical systems, such as loose connections, overloaded circuits, and faulty components. It can also be used to detect problems in mechanical systems, such as worn bearings, misaligned parts, and air leaks. Thermography can also be used to detect problems in buildings, such as moisture intrusion, air infiltration, and insulation deficiencies.
