GAS FIND IR SERIES
™
FLIR GF77
The FLIR GF77 is a groundbreaking uncooled optical gas imaging
camera with interchangeable lens options that detect methane
), sulfur hexauoride (SF6), ethylene (C2H4), ammonia (NH3), and
(CH
4
other gas emissions. Capable of both gas detection and radiometric
temperature measurement, the GF77 is an ideal inspection tool for
electric power utilities, oil and natural gas operations, chemical/
manufacturing facilities, the food and agriculture industry, and rst
responders. This camera offers unmatched versatility as well as
improved visualization of gas emissions and thermal inspections.
Based on the award-winning design of the FLIR T-Series platform,
the GF77 offers a vibrant, 4-inch touchscreen LCD, 180° rotating
optical block, and eyepiece for convenience in direct sunlight. This
affordable solution offers the benet of built-in thermographic
calibrations and the exibility to detect a wide range of gases by
simply changing lenses.
MAXIMIZE EFFICIENCY
Locate gas leaks and perform thermal
inspections with one camera
• Visualize CH
wavelengths with a versatile lens solution, and
inspect critical components using the built-in
thermal imager
• Scan for emissions from a safe distance and track
them to the source to begin repairs immediately
• Take accurate temperature measurements in all
environments from -20°C to 500°C with ±3°C or 3%
temperature accuracy
• Switch to viewnder in bright, sunlit conditions to
ensure optimal viewing
