FLIR GF77a Fixed Gas Find IR Camera
The FLIR GF77a allows oil and gas operators and other industrial markets a low-cost optical gas imaging solution for continuous operations. It is equipped with remote motorized focus and open architecture for third-party integration.
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.
FLIR’s imaging technologies like UltraMax® and MSX® ensure crisp, vibrant thermal images. The on-board FLIR Inspection Route runs pre-planned routes to help you stay organized when surveying large or multiple locations.
