Abstract

The leak detector comprises a basic unit that is connected to a probe by a hose. The probe tip is placed against test zones of the test object. In case that test gas escapes from the test object, this is detected by a test gas detector in the base unit. According to the disclosure, a position determining system is provided which comprises a transmitter, a receiver that is disposed inside the probe, and a supply and evaluation unit. Thereby, the presence of the probe tip in the individual test zones is monitored and confirmed.
