The FLIR ONE Thermal Imager is an unobtrusive lightweight accessory which will transfigure your iOS device into a potent thermal infrared camera. It utilises the FLIR ONE iPhone application to display live thermal infrared imagery, enabling you to view the world from a unique thermal perspective. FLIR ONE can also be used, amongst many other things, to measure variations in temperature. Use this technology to capture and distribute still thermal images and video, taking advantage of its exclusive MSX technology to blend thermal and visible spectrum for superior resolution and greater detail.

The FLIR ONE enables you to do your own home inspection and will help you to save money on your home energy bills. It quickly locates and identifies problems around the house, gauging the effectiveness of your insulation, finding water damage and checking for heat loss.


The FLIR ONE has a scene temperature range of -20 to 120 degrees Celsius (-4 to 248 degrees Fahrenheit) and an operating temperature range of between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit). It includes an intelligent and popular dual camera arrangement enabling both infrared and optical usage, and comes in a strong protective case.
