The Teledyne FLIR GF77a Fixed Gas Find Uncooled IR Thermal Camera continuously monitors gas emissions and delivers autonomous leak detection. It is spectrally filtered for methane and other industrial gases, has an IR resolution of 320 x 240px, <25mk thermal sensitivity, and a 25° lens. It can visualise gases in a specified spectrum while reducing false negatives of gases that absorb into other wavelengths, and includes a High Sensitivity Mode (HSM) which increases gas detectability. This lightweight, compact, and cost-effective optical gas imaging camera is compatible with RTSP, GigE, and ONVIF and features an open architecture that enables easy third-party integration. The Teledyne FLIR GF77a Fixed Gas Find Uncooled IR Thermal Camera is ideal for oil and gas facilities, gas transportation terminals, and power generation plants looking to maintain equipment, prevent production loss, meet emissions reduction metrics, and ensure the safety of their staff.
