Learn about the world of thermal imaging and its use in a variety of diagnostic applications. Everything from locating hot spots in electrical cabinets to evaluating the thermal performance of building enclosures to finding structural issues in aircraft components. Success with infrared technology, however, involves more than just learning how to use a thermal imager. IR science, heat transfer, and application knowledge are all essential. This presentation discusses the basics of what an infrared camera can do for you and provide an overview of the information that every thermographer should know.
