General description
The FLIR GFx320 is an infrared camera for optical gas imaging (OGI) in explosive atmospheres that
visualizes and pinpoints leaks of methane and other volatile organic compounds (VOCs), without the
need to shut down the operation. The portable camera also greatly improves operator safety, by detect-
ing emissions at a safe distance, and helps to protect the environment by tracing leaks of environmen-
tally harmful gases.
The FLIR GFx320 is used in industrial settings such as oil refineries, natural gas processing plants, off-
shore platforms, chemical/petrochemical industries, and biogas and power generation plants.
Benefits:
• Certified for use in an explosive atmosphere.
• Improved efficiency: The FLIR GFx320 reduces revenue loss by pinpointing gas leaks quickly and
efficiently, and from a distance. It also reduces the inspection time by allowing a broad area to be
scanned rapidly and without the need to interrupt the industrial process. The FLIR GFx320 is also
used for temperature measurement, which makes it even more useful for predictive maintenance.
• Increased worker safety: OGI allows gas leaks to be detected in a non-contact mode and from a
safe distance. This reduces the risk of the user being exposed to invisible and potentially harmful or
explosive chemicals. With a FLIR GFx320 gas imaging camera it is easy to scan areas of interest
that are difficult to reach with conventional methods. The camera is ergonomically designed, with a
bright LCD and tiltable viewfinder, which facilitates its use over a full working day.
• Protecting the environment: Several VOCs are dangerous to human health or cause harm to the en-
vironment, and are usually governed by regulations. Even small leaks can be detected and docu-
mented using the FLIR GFx320 camera.
