Helium Leak Testing - LACO Tech

Helium Leak Testing methods can be implemented in simple, manually-operated bench-top systems or in highly automated high volume production systems. This flexible method can be used with or without a test fixture or chamber, for testing "in-leakage" or "out-leakage", and both global leak testing as well as leak location. Select a leak test ...

Leak Testing Pressure Testing: Guide to Helium Leak ...

Helium leak testing at high production rates. When high volume production requires high vacuum, you must also consider the time taken to pump down to the required level of vacuum, this can be significant. At higher production rates, having much shorter time to test a part, large leakers may be a problem. ...

Helium vs. Hydrogen Leak Detection Series - Apex Vacuum

2020-11-11  While cost of the 5% H2/ 95% N2 (5/95) is less than helium, there are other factors that make the choice to use 5/95. The fact that the 5/95 is less than 25% the cost of helium will always lead the discussion, the characteristics of Hydrogen are just as important. Hydrogen is high energy and is about 3 times quicker in leaving the leak test area.
