GFx77f
Uncooled Fixed OGI Camera for Hazardous Areas
Product Variations
Keep watch over your most critical assets—without walking the site. For teams responsible for emissions detection across oil and gas and industrial facilities, the FLIR GFx77f brings optical gas imaging into demanding hazardous areas. This ATEX/IECEx system pairs the uncooled GF77a platform with a rugged enclosure to continuously monitor for methane. When an uncooled detector suits your target gas and monitoring goal, the GFx77f offers a lower-complexity option within the FLIR ADGiLE platform, delivering autonomous leak detection that helps you protect capital equipment, reduce product loss, meet emissions targets and keep workers safer.

The uncooled, spectrally filtered design provides continuous, autonomous leak detection—including patented High Sensitivity Mode (HSM)—so facilities can spot methane emissions and begin repairs immediately, without waiting on manual inspection rounds.
The AISI 316L stainless steel construction is lightweight, corrosion-resistant, and designed for easy installation and maintenance. Install multiple units across a facility to maximize leak detection with fewer in-person inspections.
Open architecture enables simple third-party integration, while dual-streaming thermal plus digital HD IP imagery lets you see more. Add in ONVIF compliance for an ease of integration with standard security and NVR solutions.
