This camera creates official reports that meet the RESNET standard that offers you with a swift and effortless way to assure that all necessities for residential thermal inspections are met.

The optimal temperature range of -4 to 482° F is considered an important aspect of the position monitoring of heat sensitivity targets.

Therefore, the thermal sensitivity of <0.10 ° C is a great help in diagnosing problems quickly and easily.

Focus Free Lens

The FLIR i7 is easy to operate and is equipped with Focus Free Lens to provide you with a final glimpse of the problem.

To provide convenient viewing, this lens offers high-resolution options that help detect leakage problems quickly and clearly.
