摘要: 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.

摘要: In leak detection, the signal generated by a test gas is superposed by interferences which fade as the vacuum generation in a container proceeds. Depending on the negative slope of the volume signal (MS), a lower indication limit (AG) is calculated. Upon activation of a zero function, the volume signal (MS) is not reduced to zero but only to the level of the indication limit (AG). Any exceeding of the indication limit is identified as a leak. Thus, the maximum sensitivity of the leak detection is guaranteed at any time.
