Facilities engineers and maintenance professionals who work with HVAC systems can benefit from learning about proper thermal imaging theory and practice, which is the focus of this informative video. The film, originally one of the sessions in the 2023 HVACR Symposium produced by The HVACR School, features instructors Eric Kaiser and Bill Spohn of TruTechTools. They highlight the uses and limitations of thermal imaging to set realistic expectations for application. Thermal imaging is especially useful for making temperature comparisons because it helps users visualize the temperature differences between multiple points. The film presents a wealth of helpful best practices information.
