Abstract

The invention relates to a test gas detector, preferably for leak detection instruments, with a selective, preferably test-gas-permeable inlet system (6) and with a device (5) recording the presence of test gas; to reduce the complexity in the production of the vacuum it is proposed that the test gas recorder (5) comprise a gas consuming vacuum gauge (8).
