  • 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.
