The helium leak test (He leak test) is an extremely precise measurement procedure for the airtightness of components (up to 1.0E-08mbar*l/sec leak threshold). Both integral measurements within the vacuum chamber as well as local measurements taken by means of sampling (sniffer) probes may be used. This process can be integrated in small manual workstations as well as in series production systems.
