FLIR offers with the GF77, two types of lenses to find a wider variety of gases with a single camera.
The new FLIR GF77™Gas Find IR Series offers professionals the flexibility to use an uncooled gas detection camera for thermal inspections in chemical and industrial manufacturing, electric power utilities, natural gas supply chain, food and agriculture, and public safety. Notable feature upgrades include the display of an entirely new category of sulfur hexafluoride, ammonia and ethylene gases. The GF77 Series also offers high IR temperature ranges, increased temperature measurement accuracy, and improved inspection/reporting flow with optional add-ons for FLIR Thermal Studio Pro and FLIR Route Creator.
The versatile FLIR GF77 does more than just view gases; this ergonomic, easy-to-use camera is calibrated for infrared temperature measurement, so inspectors can use it as part of predictive maintenance programs, such as checking tank levels and looking for electrical or mechanical problems without changing the lens.

Lens options
The GF77 Gas Find IR series offers two types of lenses, (low range (LR) and high range (HR)) in a standard 25° field of view or as a 6° telephoto lens. The LR lens has a built-in 7-8.5 µm wavelength filter for imaging methane, nitrous oxide, sulfur dioxide, R-134a and R-152a. The HR lens filters the 9.5-12 µm wavelength for imaging sulfur hexafluoride, ammonia and ethylene.
Professionals have the option of purchasing the lens combination that fits their needs, the GF77-LR, the GF77-HR, or the GF77 with the LR and HR lenses. In addition, each lens is calibrated for a specific camera body at the time of purchase to accurately display gases of interest and measure temperature.
For customers who already own a FLIR GF77 and wish to expand its capabilities, FLIR 's service center can calibrate any new lens purchased for that specific device.
Enhanced camera options
The FLIR GF77 Gas Find IR Series now includes a wider temperature detection range, from -20 °C to 500 °C, with an improved accuracy of +/- 3 °C, as opposed to +/- 5 °C, within the entire temperature range. The optional built-in routing feature, Route Creator, allows end users to simplify inspections by pre-planning the route, which includes a list of assets to be inspected at each location, reducing the risk of overlooking an asset that could cause an unexpected failure. The reporting add-on, Thermal Studio Pro, provides a simple and comprehensive final report option.
