Patent ID: 8752412

Claim:
A sniffing leak detector comprising a sniffing probe which, via a first suction line leading to a test gas sensor, is connected to a main device including a vacuum pump device, wherein the sniffing probe is provided with a second suction line which is separate from and has a higher conveying capacity than the first suction line so that the first and second suction lines can be simultaneously open, and that said second suction line can be shut off and, without connection to the test gas sensor, is directly connected to a gas conveying pump for conveyance into an environment outside of the detector, wherein the second suction line is connected to the gas conveying pump included in the main device, and wherein, within the main device, a pump device comprising a vacuum pump and the gas conveying pump is provided for generating a vacuum for the test gas sensor, and that the second suction line is connected to the gas conveying pump.
