FLIR GF620 – Optical Gas Imaging Camera

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.

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

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

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