Thermal imaging leak detection is a technology that uses infrared imaging to detect and locate leaks in a wide range of systems, including plumbing, roofing, HVAC, and electrical systems. The process involves capturing thermal images of the system, which can be used to identify areas where temperatures are different from their surroundings. This can indicate the presence of a leak, as the escaping fluid or gas will cause a temperature change. Thermal imaging leak detection is a non-invasive and non-destructive method, making it a popular choice for detecting leaks in hard-to-reach areas or in systems that cannot be shut down for inspection.
