Built for Utility Professionals
The FLIR T840 Thermal Camera is purpose-built for professionals who need to inspect electrical substations, distribution lines, mechanical systems, and industrial assets both indoors and outdoors. Featuring a rotating 180° optical block and an intuitive ergonomic grip, the FLIR T840 enables comfortable inspections from any angle – even in tight or elevated spaces.
Designed for long days in the field, the FLIR T840 helps reduce operator fatigue during all-day surveys while delivering consistently high-quality thermal images. Its rugged and weather-resistant construction ensures that it performs reliably in harsh environments – from sun-drenched substations to dimly lit plant rooms.
Superior Image Quality and IR Technology
At the heart of the FLIR T840 Thermal Camera lies advanced FLIR Vision Processing technology, combining MSX (Multi-Spectral Dynamic Imaging), UltraMax resolution enhancement, and proprietary adaptive filtering. With an IR resolution of 464 x 348 (up to 646,888 pixels with UltraMax), the FLIR T840 provides incredible clarity and sharpness that make it easy to detect hot spots, leakage, and system irregularities at a glance.
The integrated laser-assisted autofocus ensures you get tack-sharp focus on every shot, minimising human error and maximising accuracy. Combined with the bright, scratch-resistant 4-inch LCD display and integrated viewfinder, the FLIR T840 Thermal Camera delivers exceptional usability even in broad daylight or glare-heavy conditions.
Optimised for Field Efficiency
The FLIR T840 Thermal Camera is more than just a powerful imaging tool—it’s a productivity powerhouse. Thanks to its rapid reporting features, intuitive touch-screen interface, and customisable folder structure, you can stay organised and efficient without leaving the inspection site.
Need to share findings with clients or colleagues in real-time? The FLIR T840 offers Wi-Fi streaming to the FLIR Tools mobile app, making collaborative diagnostics a breeze. Embedded GPS metadata ensures that each image is accurately geo-tagged, while METERLiNK support allows for seamless integration with FLIR clamps and multimeters.
Whether you’re generating reports on-site or analysing thermal trends over time, the FLIR T840 Thermal Camera simplifies your workflow from capture to conclusion.
Avoid Downtime with Predictive Maintenance
Prevent unexpected failures and avoid costly power outages with the predictive maintenance capabilities of the FLIR T840 Thermal Camera. Regular thermal inspections help identify hot spots, worn bearings, and electrical imbalances before they escalate into critical issues. The high thermal sensitivity of the FLIR T840 makes it easier to detect even the slightest temperature variations—ensuring problems are caught early.
Its 180° rotating lens platform allows you to scan overhead lines, switchgear, and transformers from a safe distance, while the integrated viewfinder makes it possible to work efficiently outdoors, regardless of lighting conditions.
