Patent attributes
A sniffer probe is provided for a leak detector for checking the leak-tightness of gat object to be tested by means of a tracer gas. The sniffer probe includes a sniffer end piece that is configured to be connected to a pumping device of the leak detector, and a handle bearing the sniffer end piece, a capacitive proximity sensor including at least one handling detection electrode that is arranged in a grip portion of the handle, the capacitive proximity sensor being configured to send a handling detection signal that is associated with the at least one handling detection electrode to a processing unit of the leak detector in order to control the suction into the sniffer end piece according to the handling detection signal. A leak detector and a leak detection method for checking the leak-tightness of an object to be tested by means of a tracer gas are also provided.
