ABSTRACT:
Apparatus for use in the detection of leaks comprising an annular flexible, gas permeable skirt carried by and projecting from a carrier member which closes one axial end of the skirt. The opposite axial end of the skirt is closed in use by engagement with the surface being searched, such that the surface and the carrier member contain between them a sample volume bounded by the skirt. The apparatus further includes a sensing probe communicating with the sample volume for detecting the presence of a signal gas in the sample volume.
