Optical Gas Imaging
Flir optical gas imaging (OGI) cameras can help you perform infrared gas detection, spotting methane (CH4), sulfur hexafluoride (SF6), carbon monoxide (CO), hydrocarbons, and hundreds of other industrial gases quickly, accurately, and safely—without shutting down systems.
OGI cameras are fitted with specialized filters in order to detect and visualize gases that are invisible to the naked eye. This allows inspectors to 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.
Why Choose Flir OGI Cameras?
Whether you're performing leak detection and repair for methane production or mitigating gas leaks in chemical or steel manufacturing, Flir OGI technology provides the accuracy, clarity, and safety needed to find leaks efficiently.
Flir OGI cameras offer quick, highly precise infrared detection of various industrial gases. They allow you to scan wide sections of equipment and access hard-to-reach areas effectively.
Safety is guaranteed with Flir OGI cameras' ability to visualize gas leaks and display them as clouds of smoke. It allows you to identify hazardous leaks from a safe distance.
With its high-resolution capabilities of up to 640 × 480, Flir G-Series OGI cameras are effective gas detectors, offering you superior detail on small leaks from a distance.
Flir G-Series cameras for methane, hydrocarbons, and other volatile organic compounds (VOCs) embed advanced quantification analytics so you can directly measure the size of gas leaks and determine severity without requiring a secondary device.

Visualize harmful gases and Volatile Organic Compound (VOC) emissions
Whether you need higher resolution to see small leaks from a safe distance or you are looking for a more cost-effective way to find invisible methane leaks, the latest gas detection cameras from Flir offer the sensitivity and features you need to find leaks quickly and work safely.
Flir received third-party validation of the GF-Series and G-Series cameras' compliance with the following sensitivity standards.
For the NSPS OOOOa and OOOOb methane rules laid out by EPA:
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 ≤60 g/hr from a quarter inch diameter orifice.
For Appendix K to 40 CFR Part 60:
Your optical gas imaging equipment must be capable of detecting methane emissions at a rate of 19 g/hr, detecting either n-butane emissions at 29 g/hr or propane emissions at 22 g/hr, and performing at a viewing distance of 2 meters with a delta-T of 5°C in calm wind conditions (≤1 meter/second).
