FLIR i-Series Infrared Cameras i3, i5 & i7

item#: EXT152

FLIR i-Series Infrared Cameras offer high-end thermal imaging at an affordable price. These point-and-shoot infrared cameras display a thermal image with a range of -20° C to 250° C that's accurate within ±2° C on a high-resolution 2.8'' color LCD screen, making it easy to find hotspots and identify potential problems for a number of applications. All FLIR i-Series Infrared Cameras feature focus-free lenses for quick image capture, miniSD card and USB output, and a heavy-duty hard case for extra protection in the field.

The FLIR i3 and i5 cameras have been discontinued, although they are still available with an extended lead time. We recommend considering the FLIR Ex-Series cameras for users looking for an entry-level thermal camera, or the FLIR E-Series cameras for more feature-heavy models.
