Vacuum Helium Leak Testing Services Meyer Tool Mfg.

Helium leak detection is performed with a self calibrated leak detector. A vacuum of 10-6 Torr or lower is pulled on either the interior or exterior of the assembly that is being tested. A wand is used to blow a small amount of Helium around each questionable weld zone. If there is a leak in a weld, the Helium will be drawn into the vacuum and
