GF77 with 1 lens - 25HR
The FLIR GF77 is a groundbreaking uncooled optical gas imaging camera with interchangeable lens options that detect methane (CH4), sulfur hexafluoride (SF6), 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.
The GF77 is offered in several packages with high and low range lenses in both 6 and 25 degrees. The high and low range lenses can be used to detect the following:
The chart below shows the different packages available for the GF77 and the lenses which are included.
