Thermal Imaging Camera Attachment

Both models offer our revolutionary VividIR™ thermal image processing so you can see more details and provide your customers with proof that you solved their problem right the first time. Whether you’re inspecting electrical panels, looking for HVAC problems, or finding water damage, FLIR ONE Pro-Series cameras are tools no serious professional should be without.


Home & Building Inspection

Whether you’re a building contractor or realtor, FLIR ONE Pro-Series cameras give you and your customers the information they need to make important decisions thanks to our unique VividIR™ image enhancement.

HVAC & Plumbing

Whether it’s an air leak, water leak, or electrical short, FLIR ONE Pro-Series cameras can show you where to begin repairs.


Many common electrical problems create excess heat, which makes it easy to find potential electrical issues with FLIR ONE Pro-Series cameras.


If you’re a hardcore DYIer, the FLIR ONE Pro-Series will help you take your projects to the next level. Whether you’re tackling that ever-expanding to-do list around the house (and proving you did it right), or working on your favorite set of wheels, the FLIR ONE Pro and FLIR ONE Pro LT will help you do more – and do it better – than ever. Plus, you won’t have to take a home inspector’s word for it that your new house doesn’t have leaky doors or windows that have failed.



Image Detail & Clarity

Thanks to VividIRTM image processing, FLIR ONE Pro-Series cameras give you the ability to see more detail, measure smaller components from farther away, and work more safely around energized equipment.



The FLIR ONE Pro-Series’ MSX feature takes the edge detail…


Jobsite Tough

The FLIR ONE Pro-Series is built to take the abuse that working on a tough jobsite dishes out every day. Rated to take a drop from 1.8 meters, the FLIR ONE Pro and FLIR ONE Pro LT are built to last.


Expanded Measurement

FLIR ONE Pro’s expanded temperature range means you can measure temperatures between -4°F and 752°F (-20° to 400°C). With up to three spot temperature meters and six temperature regions of interest, FLIR ONE Pro gives you added on-the-go image analysis and reporting capability.


OneFit™ Compatibility

The revolutionary OneFit adjustable-height connector ensures that your camera will fit your smart device through many popular protective cases.



The upgraded FLIR ONE App offers account sign in to enable automatic warranty registration and all the latest updates from FLIR. It is engaging and shows what else you can do with your FLIR ONE. The app connects with smartwatches, includes Tips & Tricks videos, accesses the worldwide FLIR ONE community, and allows sharing to the social media of your choice.
