The FLIR GF77 Thermal and Optical Gas Imaging Camera is an optical gas imaging camera with interchangeable lens options that detect methane, sulfur hexafluoride (SF6), ethylene, ammonia, and other gas emissions. Capable of both gas detection and radiometric temperature measurement for thermal inspections, the GF77 is ideal for electric power utilities, oil and natural gas operations, chemical/manufacturing facilities, the food and agriculture industry, and first responders. This affordable solution offers the benefit of built-in thermographic calibrations and the flexibility to detect a wide range of gases by simply changing lenses.
