22.19 FLIR GF309 24° Fixed lens
P/N: 44602-0102
Rev.: 45202
General description
The FLIR GF309 is an infrared camera for furnace and high temperature inspection (e.g., of industrial fur-
naces, chemical heaters, and coal-fired boilers), without the need to shut down the operation. The port-
able camera also greatly improves operator safety, by measuring through flames at a safe distance, for all
types of furnaces. A good knowledge of the furnace condition can avert failures and unscheduled
shutdowns
Industrial furnaces, heaters, and boilers are found in the chemical, petrochemical, and utility industries.
Benefits:
• Improved efficiency: The FLIR GF309 reduces inspection time by measuring the temperature through
flames without the need to interrupt the industrial process or await scheduled service shutdowns. A
furnace camera can help you to determine how to run a furnace/boiler efficiently to give the best fuel
economy and maximize production output and quality. As the FLIR GF309 has a wide temperature
range, high-accuracy electrical and mechanical inspections can be performed, which makes the cam-
era even more useful for predictive maintenance.
• The wireless connectivity of the camera allows you to connect to smart phones or tablets for the wire-
less transfer of images or the remote control of the camera—a useful function if regulations require a
second person to accompany the furnace inspector or thermal images needs to be sent quickly for a
second opinion.
• Increased worker safety: High-temperature measurement can be performed through flames in a non-
contact mode, and from a safe distance. Custom-built, the FLIR GF309 also features a detachable
heat-shield designed to reflect heat away from the camera and the camera operator, providing in-
creased protection. The camera is ergonomically designed, with a bright LCD and tiltable viewfinder,
which facilitates its use over a full working day.
• Increased furnace safety: Good knowledge of furnace/boiler condition and operating parameters can
provide the information needed to avert catastrophic failures and prevent unscheduled shutdowns.
