Abstract
A leak detection device for combined integral and localizing leak detection, comprising a test specimen port (), a test specimen high vacuum pump (), the inlet of which is connected with the test specimen port (), at least one pre-vacuum pump (), the inlet of which is connected via a test specimen line () with the outlet () of the test specimen high vacuum pump (), and a gas detector () connected with the pre-vacuum pump (), which is connected via at least a first gas line () with the test specimen high vacuum pump (), the test specimen line () and/or the specimen port () such that gas from the test specimen port () is supplied to the gas detector () via the gas line () for gas analysis, characterized in that a gas pressure measuring volume () connected with a gas pressure sensor is configured in the test specimen line () such that, during the gas measurement with the gas detector (), an integral leak detection can be carried out by measuring the pressure profile in the gas pressure measuring volume ().
