How to Detect sf6 emissions process

The FLIR GF306 takes advantage of a spectral filter that is optimised to detect SF6 and other gases and vapours. Thermally, the camera's sensitivity is <25mK when FLIR's adaptive temporal filter is engaged. The FLIR GF306 enables thermographers to quickly and easily find SF6 gas leaks from ground level whether the leaks are nearby or meters away.
