Optical Gas Imaging (OGI) Camera for Sulfur Hexafluoride (SF₆)


Model: G306 14.5° Go to Product Support
product image

The FLIR G306 is an innovative Optical Gas Imaging (OGI) camera used to visualize sulfur hexafluoride (SF₆), ammonia (NH), ethylene (C₂H₄), and other industrial gas leaks in various environments. SF₆ is a potent greenhouse gas with a global warming potential that’s more than 23,000 times greater than C0₂ over a 100-year period. SF₆ is commonly used within the electric power industry as an insulator and quenching medium for gas-insulated substations and circuit breakers. With the portable, non-contact G306, you can safely and efficiently scan substations for dangerous and environmentally harmful gas leaks without interfering with electric utility delivery or shutting down industrial operations.

  • Superior Gas Visualization

    The FLIR G306 accurately measures temperatures from -40°C to 500°C (-40°F to 932°F) and FLIR’s patented High-Sensitivity Mode (HSM) makes (SF₆) and other industrial gas leaks stand out more clearly while allowing you to efficiently scan thousands of components

  • Improved software integration

    Built-in Wi-Fi and Bluetooth® allow you to connect to smartphones or tablets and effortlessly edit and store images in the cloud, or wirelessly transfer files using the included FLIR Ignite™ cloud service

  • Ergonomic for comfortable operation

    Comfortably operate and interact with your G306 thanks to a rotating 10.16 cm (4 in) LCD touchscreen, which allows you view targets from any direction
