The Safest Way to See Methane Leaks | FLIR GFx320
GFx320 OGI Camera | FLIR Systems

Intrinsically Safe OGI Camera

FLIR's new GFx320 represents ground breaking technology for visualizing fugitive leaks at natural gas well sites, off-shore platforms, liquid natural gas terminals, and more. Its Intrinsically Safe designation means surveyors can work confidently inside critical safety zones. And thanks to the GFx320’s ergonomic features, such as the articulating LCD screen, surveyors can work quickly and comfortably – all day.

Intrinsically Safe

The GFx320 is independently certified as “intrinsically safe,” allowing for quick detection of gas leaks while maintaining safety inside hazardous locations.

Greater Emission Reductions —
Increased Profits

The GFx320 visualizes small hydrocarbon leaks with the sensitivity needed to meet the US EPA's OOOOa methane rule. Finding and fixing these leaks can save companies thousands of dollars in lost gas and lost profits.

Superior Gas Visualization

The GFx320 is calibrated for temperature measurement to determine optimal ΔT between the gas compound and the background. It also offers FLIR's unique High Sensitivity Mode (HSM), which accentuates plume movement with through image subtraction.
