Cumulative Helium Leak Detector Pernicka 700H


Meets updated leak test procedures according to MIL-STD-883J.

Cumulative Helium Leak Detector (CHLD), a single leak testing system for sealed packages, combines mass spectrometer expertise with cryogenic ultra-high vacuum. The Pernicka 700H offers hermetic testing superior to conventional GROSS Leak and FINE leak methods. This technique can be applied to any hermetically sealed device which contains a gas such as Nitrogen, Helium, Argon, Krypton, Xenon, etc. or can be "bombed" with Helium. The Pernicka 700H is controlled by an onboard computer that makes it easy to analyze sealed objects and archive test data simultaneously. The database provides a historical record and facilitates the tracking of production yields.
