The Predator series is the newest line of thermal imaging cameras from General Tools & Instruments. The company claims that its cameras allow HVACR technicians and contractors reveal hidden heat- or cold-driven processes and problems. The Predator cameras can detect small temperature differences from a distance by converting an object’s invisible infrared radiation to a visible color image. These visual thermal signatures help diagnose equipment malfunctions and poor performance. It can also be used to pinpoint leaks sources in ductwork. Software is included with the camera to help collect data for later analysis.
