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.

The sniffing leak detector comprises a sniffing probe, a suction device and gas detector. An operator-activated switch initiates the beginning of a measuring operation. The switch starts a time measurement, wherein an alarm signal is generated by a signal transmitter at the end of a predetermined measuring period. The sniffing leak detector allows for an operator guidance from measuring point (MP) to measuring point, wherein the measuring period is predetermined and an adherence to the measuring period is monitored.

An illumination device is provided at the handle-piece of a sniffing probe, in which the illumination device illuminates the region to be inspected. This incorporation considerably facilitates handling of the sniffing probe in difficult-to-access and poorly illuminated regions, for sniffing probes used for detecting gases, for example, for detecting a gas leakage in a cooling device of a motor vehicle.
