Fixed-Mount Hydrocarbon/VOC Optical Gas Imaging (OGI) Camera

FLIR G620a

Model: FLIR G620a 14.5° Go to Product Support

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.

  • Unmatched image clarity

    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.

  • Consistent leak monitoring, without interruption

    FLIR G620a cameras offer more than 27,000 hours of runtime before any service is required (mean time to failure).

  • Meets emission regulations and reduction goals

    Satisfy U.S. EPA methane and VOC detection sensitivity requirements and achieve global ESG pledges for methane and hydrocarbon reduction.
