The Safe Way To "See" Methane Leaks

  • For Use in Hazardous Locations

    The GFx320 has third-party certifications for use in hazardous areas, allowing for quick leak detection while maintaining safety.

  • Save the Environment, and Revenue

    The GFx320 visualizes small hydrocarbon leaks with the sensitivity needed to meet the US EPA's OOOOa methane rule.

  • Advanced Quantification Capabilities

    When combined with the FLIR QL320, the GFx320's Q-Mode feature allows for easy in-field quantification of gas leaks.

The Sensitivity to Visualize Even Small Leaks

The Sensitivity to Visualize Even Small Leaks

With its superior resolution, thermal sensitivity, and the option of a High Sensitivity Mode, the FLIR GFx320 allows you to visualize leaks so you can pinpoint the exact source of the emissions and begin repairs immediately. In addition, the GFx320 can accurately measure temperatures, allowing you to note temperature differentials and improve visual contrast for better gas plume detection.
