GAS FIND IR SERIES
FLIR GF77
™
The FLIR GF77 is a groundbreaking uncooled optical gas imaging
camera with interchangeable lens options that detect methane
(CH4), sulfur hexafluoride (SF 6), ethylene (C2H4), ammonia (NH3), and
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 first
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 benefit of built-in thermographic
calibrations and the flexibility to detect a wide range of gases by
simply changing lenses.
