FLIR GF77a Gas Find IR Thermal Camera

The FLIR GF77a Gas Find IR Thermal Camera is the first uncooled autonomous leak detection camera from FLIR designed specifically to visualize methane gas. This affordable, fixed-camera solution provides upstream and midstream gas processors, producers, or operators the features they need to continuously monitor for potentially dangerous, invisible methane leaks. Small and lightweight, the FLIR GF77a is packed with FLIR-patented features, such as High Sensitivity Mode (HSM), for improved gas visualization. The GF77a can help oil and gas companies maintain valuable capital equipment, avoid product loss, meet emissions reduction metrics, and ensure safer work practices.

Continuous, autonomous methane gas detection


Offers industry-leading features for continuous monitoring applications including High Sensitivity Mode, remote motorized focus, and open architecture for third-party integration.


Spectrally-filtered to detect methane gases, improving worker safety and leak location identification with fewer in-person inspections.


RTSP, GigE and ONVIF compliant, the GF77a offers flexibility to meet many industrial communication needs and connects to a network for continuous leak detection.
