22.25 FLIR GF343 24° Fixed lens
P/N: 65702-0102
Rev.: 45202
General description
The new FLIR GF343 is an optical gas camera for visualizing carbon dioxide (CO
2
). With this camera you
can quickly and easily find gas leaks where CO
2
is the main component.
Key features:
• Visualizes gas leaks in real time.
• Inspects without interruption of process.
• Traces leaks to their source.
Carbon capture and storage—stop the escalation of global warming:
• A global transition to a sustainable low-carbon economy is a necessity.
• Global energy demand is still dominated by fossil fuels being combusted in quantities incompatible
with levels required to stabilize greenhouse gases concentrations at safe levels in the atmosphere.
CO
2
(R744)—the new environmental friendly refrigerant:
• Air-conditioning for cars—replaces R134a.
• CO
2
-based heat pumps.
• Electrical power—replaces sulfur hexafluoride.
CO
2
—a harmless tracer gas:
• Use CO
2
to trace leaks.
Note
The CO
2
background level in the atmosphere varies between about 400 ppm (e.g., outdoors) to 5000
ppm (e.g., very high levels indoors), and the ability to see a CO
2
leak using the FLIR GF343 depends on
this gas concentration and also on the distance to the target. For example, an outdoor leak at a distance
of 10 m (33′) adds 4000 ppm × m to the gas concentration length.
