General Tools was started by a husband and wife team in New York City in 1922. To this day the company remains owned "in the family." Initially the company sold hardware and hand tools for home and commercial use. Today the company product line has expanded to include a range of specialty tools designed and made exclusively by General Tools. Included in this specialty line is General Tools' own line of thermal  imaging cameras.
The General Tools thermal camera is known as the "Predator" series. Designed specifically for building diagnostics and HVAC performance evaluation, these capable and affordable thermal cameras can easily detect small or large temperature differences from a distance. HVAC professionals, electricians, plumbers, and building inspectors can use these thermal cameras to effectively locate and pinpoint invisible or inaccessible thermal leaks, inspect integrity of thermal insulation, detect specific areas of energy loss, and support maintenance and repair efforts by documenting problem areas. General Tools thermal imaging cameras cover -4° to 572°F, with an option to upgrade to a maximum readable temperature of 2732°F. With this versatility you can be sure your test areas will always be readable by the camera. Combine that with 620 x 480 pixel resolution and a 3 year warranty and you have a capable thermal camera backed by a support network to be reckoned with.
