Thermal inspection, also known as thermography or thermal imaging, is a non-destructive testing technique that involves the use of infrared cameras to detect and measure thermal energy emitted by objects.
​
The basic principle of thermal inspection is that all objects emit infrared radiation in the form of heat. By using an infrared camera, the energy emitted by an object can be captured and converted into an image that shows variations in temperature. These images are then analyzed to identify areas of temperature differences that may indicate anomalies, such as hotspots or cold spots.
Thermal inspection is used in a wide range of applications, including building inspections, electrical inspections, and mechanical inspections. In building inspections, thermal imaging can be used to detect insulation defects, air leaks, and moisture intrusion. In electrical inspections, thermal imaging can be used to detect hotspots in electrical equipment, indicating potential electrical faults. In mechanical inspections, thermal imaging can be used to detect abnormal heat patterns in machinery, indicating potential mechanical problems.

Thermal inspection can provide valuable information about the condition of objects or systems without requiring physical contact, making it a safe and efficient testing method. It can also identify potential problems before they become more serious and costly to repair.
