FLIR T540

Professional Thermal Camera

Diagnose potential faults in industrial, electrical, and mechanical systems, or discover temperature anomalies in R&D testing with the 464 × 348 resolution FLIR T540. This portable, ergonomic thermal camera offers advanced features like 1-Touch Level/Span and continuous laser-assisted autofocus, making it the perfect non-contact diagnostic tool for condition monitoring and research applications. Streamline electrical/mechanical surveys, troubleshooting, and repairs with Inspection Route mode, which runs pre-planned routes created in FLIR Thermal Studio Pro so users can record temperature data and imagery in a logical sequence. The built-in Macro Mode allows R&D users to quickly switch from wide angle to close-up analysis without changing the lens. Or pair the T540 with a FLIR FlexView® dual field-of-view lens for the convenience to instantly switch from wide-area to telephoto scanning. When coupled with Research Studio software, the T540 helps engineers assess unexpected hot spots and find potential design flaws.

Resolution, Comfort, And Outstanding Performance

Make Critical Decisions Quickly
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.
