High-definition optical gas imaging camera


FLIR Systems has launched a high-definition (HD) hand-held optical gas imaging (OGI) camera, the FLIR GF620.

Designed for oil & gas industry professionals, it is claimed the FLIR GF620 camera sets a new standard for detecting and visualising invisible leaks of hydrocarbons, such as methane, and common volatile organic compounds (VOCs). With four times the pixels of previous models, the HD-resolution FLIR GF620 helps inspectors survey for fugitive hydrocarbon emissions from further, safer distances than is possible with OGI cameras of lower resolution.

The new FLIR GF620 is the company’s highest resolution OGI camera. Equipped with a 640 × 480 infrared detector, the camera is calibrated to measure temperature, allowing the user to assess the thermal contrast between the gas and the background scene and adjust it to improve visibility. The FLIR GF620 also features the company’s unique high-sensitivity mode, which accentuates plume movement to improve detectability in low-contrast scenes.

The FLIR GF620 also introduces Q-Mode, an automatic preset for use with the QL320 gas quantification system from Providence Photonics. This system quantifies hydrocarbon leaks with mass or volumetric measurements and colourises emissions for easier assessment. Q-Mode streamlines the workflow from the camera to the software, so as users can download a video from the field and post-process the footage.

The FLIR GF620 features an ergonomic design that allows professionals to safely inspect for fugitive emissions more comfortably and for longer hours of operation. It also enables maintenance crews to use the temperature measurement feature for inspecting electrical and mechanical components for signs of wear or potential failure.
