Reveal hidden heat-driven processes and problems with the General Tools GTi20 "Predator" Series Thermal Image Camera. By rendering an object's infrared (IR) radiation as visible images, thermal imaging cameras make it possible to detect very small temperature differences from a distance. Heat signatures can help diagnose the cause of equipment failures and poor performance due to wear and tear, misalignments and fault conditions.

GTi20 package includes GTi20 camera, two (2) rechargeable Li-ion batteries, AC adaptor, compact battery charger, 2GB MiniSD memory card, SD card reader, video cable with BNC plug, USB 2.0 Cable, lens cap, analysis & reporting software on CD, calibration certificate, hand & neck Straps, custom hard case and user's manual.
