FLIR GF309 Gaskamera (24° linse)

Through-Flame
FLIR GF309 is equipped with a special midwave “flame filter” engineered to see in the high temperatures (up to 1,500˚C) encountered during industrial furnace and boiler inspections. A nickel-coated heat shield improves worker safety and comfort during inspection.Add the furnace IR 14.5-degree lens extender to measure the temperature of furnace tubes and ovens through small view ports.

Furnace Inspection – The GF-309 gives inspectors clear thermal imagery of fired product tubes, allowing them to distinguish between internal coking and external scaling, helping to avoid costly tube overheat failures. The ability to identify coking also allows for proper planning of unit shutdowns and de-coke procedures. 

Burner Alignment – With the GF-309’s specialized filters, inspectors can accurately scan for proper burner alignment and check for flame impingement, identifying if the flame pattern is causing localized tube overheating.

Fire Box Inspection – Its wide temperature range makes the GF-309 well-suited for external firebox inspections, detecting the hot spots on the outside of a firebox that indicate a problem with the internal refractory bricks or insulating blankets.

Coal-Fired Boilers – The GF-309 is ideal for identifying slag buildup that can potentially interfere with heat transfer, cause localized tube corrosion, and result in catastrophic mechanical failure when the slag “clinkers” fall.
