  • Test procedure - DILO

    For the laser-optic test method SF 6 gas is used as tracer gas for integral detection in the production of serial parts (chamber method), i. e. the test object is tested for tightness by filling it with SF 6 gas under vacuum. This test method allows precise determination of the total leak rate of a component.
