PCT No. PCT/EP94/02311 Sec. 371 Date Feb. 1, 1996 Sec. 102(e) Date Feb. 1, 1996 PCT Filed Jul. 14, 1994 PCT Pub. No. WO95/04921 PCT Pub. Date Feb. 16, 1995The 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).
