The FLIR GF309 is an IR camera for the high-temperature measurement of industrial furnaces, chemical heaters, and coal-fired boilers, without the need to shut down the operation. The portable 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.

	See through flames The GF309 is equipped with a special “flame filter” that allows you to see and measure high temperatures (up to +1500°C) through flames. Ideal for furnace and boiler inspections.
	Wide temperature range The FLIR GF309 visualizes temperatures from -40°C to +1,500°C. This makes the camera extremely suited for high temperature inspections.
	Dual use The FLIR GF309 can be used both for internal and external furnace and maintenance inspections and can make also the smallest of temperature differences clearly visible.
	Heat shield A nickel coated heat shield improves worker safety and comfort during inspection.
	Available lenses The FLIR GF309 comes either with a fixed 14.5° lens or with a fixed 24° lens. A version with interchangeable lenses is also available but requires a US Department of State license.
	Cooled detector The FLIR GF309 contains a cooled Indium Antimonide (InSb) detector. This highly sensitive detector is spectrally tuned to 3.8 - 4.05 micrometer waveband for seeing through flames.
