Abstract
The leak detector includes a basic device which includes a vacuum pump, a test gas sensor, and a hand-held sniffing probe. The sniffing probe is connected with the basic device via a flexible hose line which includes capillary tubes. At least two capillary tubes are provided, which are adapted to be opened via valves. Thus different capillary cross sections can be rendered operative. The dead time between the entry of the test gas into the sniffing probe and the detection by the test gas sensor can be changed and/or selected. Thus, even the smallest detectable leak rate can be changed and/or selected. The leak detector can be adapted to different requirements by the user without the need for exchanging the hose line. Further, it is possible to equip different leak detectors of the same device family with the same hose lines.
