Handheld Optical Gas Imaging Camera

A handheld optical gas imaging camera is a specialized infrared imaging instrument that visualizes the presence of gas leaks and volatile organic compound emissions as visible plumes in the camera’s display, allowing operators to detect, locate, and assess gas leaks from pipelines, valves, flanges, compressors, and storage vessels without requiring contact measurements or shutting down operating systems. Unlike point-sensor gas detectors that must be positioned directly at the leak source, optical gas imaging cameras detect the infrared absorption signature of target gas compounds within the camera’s field of view from distances of up to 30 meters or more, enabling rapid large-area leak surveys from a safe standoff distance.

The imaging system uses a cooled or uncooled infrared focal plane array sensitive to the mid-wave infrared band between 3.2 and 3.4 µm or the long-wave band between 8 and 12 µm, matched to the specific absorption wavelengths of the target gas compounds. Gases detectable by professional optical gas imaging cameras include methane, propane, butane, ethane, benzene, toluene, xylene, sulfur hexafluoride, and refrigerant compounds depending on the spectral filter fitted to the instrument. Minimum detectable quantity for methane on professional-grade cooled systems reaches below 1 gram per hour under favorable wind and background conditions.

Display modes include standard infrared imaging, high-sensitivity gas visualization overlay, and color-enhanced plume display for improved operator detection confidence. Integrated visible light cameras on most models allow simultaneous optical and infrared imaging for precise leak location documentation.
