About FLIR


​The FLIR GF320 is an IR camera for optical gas imaging (OGI) that visualizes and strong pinpoints leaks of VOCs, without the need to shut down the operation.

The FLIR GF300/320 infrared camera is a preventative maintenance solution to spot leaks in piping, flanges and connections in petrochemical operations.

The portable camera also greatly improves operator safety, by detecting emissions at a safe distance, and helps to protect the environment by tracing leaks of environmentally harmful gases. The GF320 is used in industrial settings such as oil refineries, natural gas processing plants, offshore platforms, chemical/petrochemical industries, and biogas and power generation plants.

Cover the same area as traditional methods in 99% less of the time
Literally thousands of components can be scanned per shift without the need to interrupt the process. It reduces repair downtime and provides verification of the process. Above all it is exceptionally safe, allowing potentially dangerous leaks to be monitored from several meters away. FLIR GF300/320 will significantly improve your work safety, environmental and regulatory compliance, not to mention helping to improve the bottom line by finding leaks that essentially decrease profits. The new GF300/320 now embeds GPS data into the image allowing workers to pinpoint the location of the leak or hot spot.

Gas sniffers versus thermal imaging cameras

In a complex petrochemical facility there may be many thousands of potential leak paths. Some may be leaking but most will not. Conventional leak detection equipment such as a Volatile Organic Compound meters (or sniffers) mean that the operator must visit and test each potential leak site. Each item must therefore be accessible or made accessible to be tested. Gas sniffers may expose inspectors to invisible and potentially harmful chemicals.

Using gas detection cameras allows the user to examine many potential leak sources in a short time and from a distance.

Infrared thermometers vs thermal imaging cameras

Infrared (IR) thermometers are reliable and very useful for single-spot temperature readings, but, for scanning large areas or components, it’s easy to miss critical components that may be near failure and need repair.

A FLIR thermal imaging camera can scan entire motors, components, or panels at once -never missing any overheating hazards, no matter how small.
