Abstract
The invention relates to a leak detector including a hand-held device with a sniffer tip. A distance detector for detecting a defined distance of the sniffer tip from the test object is provided on the sniffer tip. A test is only initiated if the distance between the sniffer tip and the test object is correct, thereby avoiding measuring errors due to wrong manual positioning of the sniffer probe. The leak detector can also be provided with an acceleration detector, which permits the test to be carried out only if the sniffer probe is kept steady.
