The FLIR GF343 is an optical gas imaging camera that lets you see carbon dioxide leaks quickly, easily, and from a safe distance. Whether CO2 is a byproduct of a production process, a trace gas used to detect hydrogen leaks from power generators, or part of an enhanced oil recovery program, fast and accurate detection of CO2 is key to keeping your operation running safely, efficiently, and profitably.

Fast, Unbeatable Gas Detection

  • Visualize Gas in Real Time

    The GF343 displays the optical gas image in real-time, so you can quickly scan large areas for signs of gas emissions.

  • Trace Hydrogen Leaks to their Source

    By adding 3-4% CO2 to hydrogen as a tracer gas, the GF343 can localize leaks and verify repairs.

  • Decrease Downtime, Save Money

    Use the GF343 during regular operations to find leaks and confirm repairs—avoiding outages as well as costly regulatory fines.

The Sensitivity to Visualize Even Small Leaks

The Sensitivity to Visualize Even Small Leaks

With its dedicated filter, thermal sensitivity, and the option of High Sensitivity Mode (HSM), the FLIR GF343 allows you to visualize leaks so you can pinpoint the exact source of the emissions and begin repairs immediately. Improve your reliability program and increase worker safety by finding leaks before they cause an issue with this dedicated CO2 gas imaging camera.
