FLIR GF77-25-LR-HR Thermal Imaging Camera with 25 Low-Range and 25 High-Range Lenses, 320 x 240 Resolution, 30 Hz Frame Rate, Industrial Gas Detection

The Teledyne FLIR GF77-25-LR-HR Thermal Imaging Camera is a powerful uncooled optical gas imaging solution designed for both industrial gas detection and thermal inspections. Equipped with two interchangeable lenses—25° low-range and 25° high-range—it enables precise visualization and quantification of gases such as methane (CH4), sulfur hexafluoride (SF6), ammonia (NH3), and ethylene (C2H4). Its radiometric capabilities support temperature measurements from -20°C to 500°C, making it suitable for a variety of industrial applications.

Built on the award-winning T-Series platform, the camera features a high-resolution 4-inch LCD touchscreen, an eyepiece for use in bright sunlight, and a rotating optical block for ergonomic operation. Enhanced connectivity through the Teledyne FLIR cloud simplifies data transfer, storage, and sharing. Whether monitoring critical components in electric utilities or scanning oil and gas infrastructure, this camera offers unmatched flexibility and efficiency.
