- Usually ships in 3 business days
Description
The FLIR GF77a Fixed-Mount Gas Imaging Camera is an uncooled OGI camera for continuous, automated gas leak monitoring at well sites, compressor stations, and process facilities. Mounted once, it watches for methane and other gas leaks around the clock and alarms through your control system.
The GF77a provides 320 × 240 thermal imaging with thermal sensitivity under 25 mK, in LR (7-8.5 µm) or HR (9.5-12 µm) spectral versions covering methane, hydrocarbons, SF6, ammonia, and more. GigE and RTSP connectivity, ONVIF-friendly integration, and a compact weatherproof housing make it a practical fixed sensor for emissions monitoring programs.
- First uncooled fixed-mount autonomous optical gas imaging camera for continuous leak detection
- Two variants: GF77a-LR (7-8.5 µm) visualizes methane, nitrous oxide, propane, sulfur dioxide, R-134a and R-152a; GF77a-HR (9.5-12 µm) visualizes SF6, ammonia and ethylene
- RTSP and GigE Vision / GenICam compliant with Wi-Fi, so it connects to a network for continuous monitoring and third-party analytics
- FLIR-patented High Sensitivity Mode (HSM) makes gas plumes easier to see
- Radiometrically calibrated — also monitors tank levels and overheating components
- Remote motorized focus and open architecture for integration
- GF77f variant adds an environmental housing for harsh environments (RJ45 connector, fixed focus, 510 × 177 × 229 mm, 5.90 kg); GF77pt variant adds pan/tilt control
- ONVIF compliant (per FLIR launch materials)
Typical Applications
- Continuous emissions monitoring
- Well pads and compressor stations
- Gas processing plants
- Fenceline and safety monitoring
