Fixed-Mount Hydrocarbon/VOC Optical Gas Imaging (OGI) Camera
Find gas leaks while meeting governmental and environmental emission goals with the FLIR G620a: a long-lived, cooled OGI camera solution for continuous monitoring at upstream and midstream gas production and processing facilities. The G620a is spectrally filtered to see methane (CH₄), hydrocarbons, and Volatile Organic Compounds (VOCs) with a performance OGI detector that meets sensitivity requirements set forth in U.S. EPA OOOOa and Appendix K. Small and lightweight, the G620a installs quickly and relies on a simplified web interface. Never miss a moment of monitoring thanks to the robust linear cooler which supports 27,000 hours of non-stop operation. The FLIR G620a can help oil and gas companies maintain valuable capital equipment, avoid product loss, meet emissions reduction metrics, and ensure safer work practices.
The high-resolution, high sensitivity cooled image sensor plus the advantage of FLIR’s proprietary High Sensitivity Mode (HSM) allows users to visualize even the smallest gas leaks.
FLIR G620a cameras offer more than 27,000 hours of runtime before any service is required (mean time to failure).
Satisfy U.S. EPA methane and VOC detection sensitivity requirements and achieve global ESG pledges for methane and hydrocarbon reduction.
