FLIR T540 w/42° & 14° Lens, 464×348, -20°C to 1500°C and FLIR Tools+

Troubleshoot hotspots, find hidden faults, and confirm repairs with the ergonomic,      high-resolution FLIR T540. This 161,472 pixel thermal imaging camera has a bright 4″ LCD and a 180° rotating lens platform, so you can easily and comfortably diagnose electrical or mechanical issues, even in hard-to-reach areas.

Advanced on-camera measurement tools such as 1-Touch Level/Span, plus laser-assisted autofocus, ensure you’ll record accurate temperature measurements every time.




    Laser-assisted autofocus guarantees you’ll get tack-sharp focus for accurate temperature readings that lead to quick but solid decisions.


    The T540’s optical block rotates 180°, so you can image targets at any angle—comfortably—all day long.


    The capacitive touchscreen with intuitive menu is easy to navigate, plus you can customize with two programmable buttons.

Outstanding Image Clarity


The T540 uses the power of FLIR Vision Processing™ to deliver detailed, smooth pictures with very little image noise. FLIR Vision Processing combines IR resolution, MSX®, and UltraMax® image enhancement with FLIR’s proprietary adaptive filtering algorithms to produce brilliant thermal images with up to 3.1 million pixels. Plus, the T540 is sensitive enough to detect temperature differences down to <30 mK for clear, low-noise results.
