We create machinery for helium leak detection using different test methods depending on the type of component to be tested.

Spraying test (Vacuum Test)

The part to be tested is directly connected to a mass spectrometer and put inside a chamber.
Vacuum is created inside the part and the helium concentration in the chamber is raised to 100%.
If a leakage is present, the molecules of helium migrate into the part and the leakage is measured by the spectrometer.
1. The test is objective, since does not depend on the operator.
2. The possible leak range to be detected is from 5.0 x 10-3 mbar*L/s to 5.0 x 10-8 mbar*L/s.
3. This test is frequently used to check porosities in cast parts or for parts that operate under vacuum, as water pumps and brake pumps.
