The FLIR GF620 is the first high-resolution, handheld camera from FLIR to detect methane and other volatile organic compound (VOC) emissions. With its ground-breaking 640 x 480 resolution IR detector, inspectors can check thousands of components and safely scan for gases from greater distances. It's also the first FLIR OGI camera to offer Quantification mode (Q-Mode) for streamlined set-up of the optional QL320 gas quantification system.

The Next Generation in OGI Technology

  • See more and survey safer

    See smaller leaks using the same optics and distances as earlier models, thanks to a 4x increase in pixels within the field of view.

  • Sensitive enough for small leaks

    Measure temperature up to 100°C with ±1°C accuracy so you can ensure optimal contrast, or improve detection with High Sensitivity Mode (HSM).

  • Save the environment and revenue

    Reduce emissions and avoid regulatory fines by pinpointing the exact source of emissions and quantifying losses with Q-mode and the optional QL320 system.
