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.
