Apparatus for and method of testing leakage of hollow member |
摘要 |
A leakage testing apparatus for testing whether or not a hollow member of a hollow shape has a leakage, comprising: a hold mechanism for holding the hollow member such that the inside and the outside are isolated gas-tight from each other; an injection mechanism for injecting a testing gas into the hollow member held by the hold mechanism; and a leakage detector for sucking the gas around the hollow member held by the hold mechanism, to detect the leakage on the basis of the concentration of the testing gas in the sucked gas.
