Sniffing Test

Sniffing Test
詳細

The part is pressurized with helium. The mass spectrometer is fitted with a sniffer probe that is moved over the areas of possible leak to detect its presence. The test

can be performed manually (by operator) or automatically.

The detectable leak range is between 5.0 x 10-3 mbar*L/s and 5.0 x 10-5 mbar*L/s.

This test is used for parts that cannot be put inside a vacuum chamber (refrigerators, refrigerated food displays) or to locate a leak that has been detected by other methods, in order to allow for parts repair.
