The FLIR GF77a 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. The GF77a also comes in a GF77f variant that includes environmental housing for harsh environments.
