Fixed GasFindIR camera
FLIR GF77a
The FLIR GF77a is FLIR's first uncooled stand-alone leak detection camera specifically designed to image methane gas. This affordable fixed camera solution provides upstream and midstream gas processors, producers or operators with the features they need to continuously monitor for invisible and potentially dangerous methane leaks. The small and lightweight FLIR GF77a is equipped with numerous patented FLIR features, such as High Sensitivity Mode (HSM) for enhanced gas visualization. The GF77a can help oil and gas companies maintain purchased equipment, avoid product loss, comply with emission reduction regulations, and ensure safer working practices.
Affordable fixed OGI solution
It offers other industry-leading features for continuous monitoring applications, such as high-sensitivity mode, remote motorized focusing and open architecture for integration of third-party products.
Display industrial gases
With spectral filtering for methane gas detection, improving worker safety and leak location with fewer face-to-face inspections.
Unmatched connectivity
The RTSP and GigE compatible GF77a offers flexibility to meet many industrial communication needs and connects to a network for continuous leak detection.
