The Teledyne FLIR GF77-25-LR-HR-6-LR Thermal Imaging Camera is an advanced uncooled optical gas imaging solution equipped with interchangeable low-range (25° and 6°) and high-range (25°) lenses. Designed for industrial gas detection and thermal inspections, it can detect methane (CH4), sulfur hexafluoride (SF6), ethylene (C2H4), ammonia (NH3), and other emissions across varying spectrums. With a 320 x 240 IR resolution and 30 Hz refresh rate, this camera delivers real-time analysis for professionals working in utility, oil and gas, food production, and emergency response sectors.

Its compact and rugged design, based on the award-winning T-Series platform, includes a 4-inch touchscreen LCD and a rotating optical block for maximum usability. The GF77 enables radiometric temperature measurement from -20°C to 500°C with high accuracy, and it supports a full range of features including GPS tagging, Wi-Fi connectivity, high-sensitivity mode, and laser-assisted autofocus.
