The invention relates to a sniffer probe () for drawing in gas when searching for gas leaks, the sniffer probe having at least one sniffer tip (), and an intake opening () being provided which is connected via a connecting line to a main sniffer line which can be connected to a gas leak detector. The sniffer tip () is provided in the region of the intake opening () with flexible elongated shielding elements () which project from the sniffer tip () in such a way that the intake opening () is shielded from the exterior environment () of the sniffer probe () on all sides.

The invention relates to a method for leakage detection on at least one flexible test piece in a film chamber, including inserting the at least one test piece into a film chamber, lowering the pressure in the film chamber outside the at least one test piece, and detecting a leakage in the at least one test piece by observing the spatial change of the film of the film chamber. The outer contour of the at least one test piece is transferred to at least one section of the film by the lowering of the pressure in the film chamber. The contour of the film is recorded with an image recording system, and the recorded images of the contour are compared with reference images of said contour in the event of a tight test piece.

The invention relates to a gas leakage search device including a test gas spray device for spraying a test object with a test gas, a vacuum assembly for evacuating the test object, wherein the vacuum assembly has a vacuum pump and a gas detector downstream of the test object for measuring the test gas proportion, and an analysis unit which evaluates the measurement signal of the gas detector. The invention is characterized in that a data communication connection is established between the spray device and the analysis unit; the spray device is designed to detect at least one point in time of the spraying process and to transmit same to the analysis unit, and the analysis unit is designed to output the corresponding measured test gas proportion at the transmitted point in time of the spraying process.
