The FLIR Gx320, G620, and Gx620 are innovative Optical Gas Imaging (OGI) cameras designed to detect hydrocarbons, methane (CH₄), and other Volatile Organic Compound (VOC) emissions from multiple stages of the oil and gas supply chain, as well as other industrial markets. With up to 640 × 480 (307,200 pixels) thermal resolution, FLIR G-Series cameras have innovative gas quantification analytics that measure leak type and severity inside the camera, eliminating the need for a secondary device. While all models are OOOOa certified, the FLIR Gx320 and Gx620 are ATEX compliant, making these camera models ideal for detecting gas emissions in complex systems including refineries, petrochemical facilities, natural gas well pads, compression stations, and power generation plants.
