hitachi SF6 gas plant leak rate

The inert gas sf 6 (sulphur hexafluoride) is used in component testing. As the gas cannot be found in ambient air, a highly precise and pure test result can be guaranteed. The new leak test unit virtually does "detective work" for it is able to trace smallest sf 6 leakages. Even leakage rates down to 1*10 -9 mbar l/s can be easily detected.
