FLIR GF77
Uncooled Optical Gas Imaging Camera
Product Variations
Detect Gas Leaks at Substations and More
The FLIR GF77 is a groundbreaking uncooled 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. The purchase of a GF77 camera includes a 3-month subscription to FLIR Thermal Studio Pro and FLIR Route Creator.
A Versatile Solution for Gas Detection and Thermal Inspection
Safely locate gas leaks and perform accurate thermal inspections using one camera.
From laser-assisted autofocus to 1-Touch Level/Span contrast enhancement, the GF77 offers the latest high-tech features while remaining affordable.
Work easier with the ergonomic design, tools to organize findings in the field such as GPS, Wi-Fi, and annotation, plus rapid-reporting capabilities.
Improve Image Clarity and Gas Detection with Advanced Features from Flir
The GF77 is calibrated for temperature, so you can manually adjust contrast between the gas cloud and the background. Or, increase contrast instantly with the 1-Touch Level/Span auto-adjustment feature. Finally, accentuate plume movement with FLIR High Sensitivity Mode (HSM).
