Patent ID: 8893543

Claim:
A leak detection method that employs a suction tube, that is coupled to a conveyor unit via a flexible hose, to generate an air flow, wherein a non-enclosed specimen filled with a test gas is exposed to the air flow, wherein, in the ambient atmosphere, the air flow is passed across substantially the entire surface of the non-enclosed specimen in the form of an undirected flow exclusively by suctioning into the suction tube, wherein the suction tube includes a first partial-flow extraction site that branches off from the suction tube, and the flexible hose includes a second partial-flow extraction site that branches off from the flexible hose downstream from the first partial-flow extraction site, each partial-flow extraction site having connected thereto a test-gas detector and a vacuum pump for diverting the partial flow of the air flow to the corresponding test-gas detector such that each partial flow is tested independent of any other partial flow.
