• gaz sf6 LeakCheck P1:P Sulfur Hexafluoride Leak Detector | Gastech

    The sf 6 gas leak detector also benefits from having a non­radioactive source, eliminating registration, storage and transportation issues found with traditional radioactive ECD Sulfr hexafluoride gas leak detectors. Additional features of the sf 6 gas leak detector include data­logging, alarms; both audio and visual, and a robust portable case.

  • Sulfur hexafluoride detection by Radar resonance enhanced

    In order to obtain a well defined spectral signature, the sulfur hexafluoride molecules are first dissociated by a focused pulsed Nd:YAG laser to sulfur difluoride molecules, which are then ionized by a pulsed, frequency tunable, narrow linewidth laser emitting in the ultraviolet. At the wavelength 269.5 nm, a concentration of 10 % of sulfur hexafluoride has been detected and the spectral signature shows some overlap with a carbon dioxide resonant spectral line.
