Optical Gas Imaging

FLIR optical gas imaging (OGI) cameras can help you detect methane, sulfur hexafluoride, and hundreds of other industrial gases quickly, accurately, and safely - without shutting down systems. With FLIR OGI cameras, you can scan broad sections of equipment rapidly and survey areas that are hard to reach with traditional contact measurement tools. OGI cameras can also detect leaks from a safe distance, displaying these invisible gases as clouds of smoke.

See hydrocarbon leaks clearly

Scan thousands of connections for natural gas (methane) and other hydrocarbon leaks quickly and from a safe distance to avoid regulatory violations, fines, and lost revenue.


Intrinsically Safe OGI Camera

FLIR received third-party validation of the FLIR GFx320, GF320, GF300, and G300a cameras' compliance with the following sensitivity standard laid out by the EPA in the NSPS OOOOa methane rule:

Your optical gas imaging equipment must be capable of imaging a gas that is half methane, half propane at a concentration of 10,000 ppm at a flow rate of ≤60g/hr from a quarter inch diameter orifice.

10 Tips for Getting the Most Out of an Optical Gas Imaging (OGI) Camera

Optical Gas Imaging (OGI) cameras use spectral wavelength filtering and Stirling cooler cold-filtering technology to visualize the infrared absorption of gases such as methane (CH4) sulfur hexafluoride (SF6), carbon dioxide (CO2), and refrigerants.
