Gas Find IR
FLIR GF77
Model: FLIR GF77 25° RH (from 7 to 8.5 µm) + 25° RH (from 9.5 to 12 µm) + 6° LR (from 9.5 to 12 µm)
The FLIR GF77 is an innovative uncooled optical gas detection camera with interchangeable lens options that detect methane, sulfur hexafluoride (SF6), ethylene, ammonia and other gas emissions. Capable of both gas detection and radiometric temperature measurements for thermal inspections, the GF77 is ideal for utilities, oil and natural gas operations, chemical facilities or factories, food and agriculture, and emergency services. This affordable solution offers the advantage of built-in thermographic calibration and the flexibility to detect a wide variety of gases by simply changing the lens. The purchase of a GF77 camera includes a 3-month subscription to FLIR Thermal Studio Pro and FLIR Route Creator.
