Abstract (en)
[origin: WO03042651A1] The invention relates to a test gas leakage detector (1), comprising an inlet (2) for gases to be analyzed for the presence of a test gas, a test gas detector (22), a high vacuum pump system (15) connected to the test gas detector, an intermediate inlet (14) arranged on the high vacuum pump system (15) and used to supply the gases to be analyzed for the presence of a test gas, a fore-vacuum pump (8) connected to high vacuum pump system (15) and a line section (3,6) fitted with a valve (5) and located between the inlet (2) and the fore-vacuum pump (8). In order to provide a device of the above-mentioned category which is quicker and more sensitive, another high vacuum pump (11) is provided between the inlet (2) and the intermediate inlet (14), having an outlet (12) which is connected to the inlet (7) of the fore-vacuum pump (8) by means of a line section fitted with a valve (17).
