  • Vacuum Test Chambers for SF6 Leak Testing - DILO

    When testing SF 6 -filled control system components, SF 6 can remain in the test object after testing. This makes the SF 6 test method an interesting alternative to the known helium leak test in the field of GIS production, as it is not necessary to recover the test gas from the test chamber after completion of the test process.
