Description
The FLIR GF77 Gas Imaging Camera is an uncooled optical gas imaging (OGI) camera that makes invisible gas leaks visible — no contact, no process shutdown, and no cooled detector to maintain. Choose the lens configuration for your target gases at checkout.
The GF77 uses interchangeable spectral-filter lenses: the LR (7-8.5 µm) lens for methane and many hydrocarbons, and the HR (9.5-12 µm) lens for sulfur hexafluoride (SF6), ammonia, and ethylene. Its 320 × 240 detector, thermal sensitivity under 25 mK, and 1-Touch Level/Span keep leak plumes obvious in the field, and it doubles as a standard thermal camera for electrical and mechanical inspections.
- Uncooled optical gas imaging camera that visualizes invisible gas leaks plus full radiometric temperature measurement in one tool
- Interchangeable LR (7-8.5 µm) and HR (9.5-12 µm) lenses — swap lenses to detect different gases (calibration by FLIR service may be required)
- LR detects methane, nitrous oxide, propane, sulfur dioxide, R-134a and R-152a; HR detects SF6, ammonia and ethylene
- FLIR-patented High Sensitivity Mode (HSM) accentuates plume movement for better leak visibility
- Laser-assisted autofocus and 1-Touch Level/Span on the ergonomic T-Series platform with eyepiece
- Built-in thermographic calibration lets you check component temperatures while hunting leaks
- GPS, Wi-Fi and annotation tools for documented inspections
- Purchase includes a 3-month FLIR Thermal Studio Pro + Route Creator subscription (per page copy)
Typical Applications
- Methane leak detection (LDAR)
- Oil and gas production and pipelines
- SF6 and refrigerant leak checks
- Utility and chemical plant inspections
