Abstract

A sniffer leak detector is provided herein, including a sniffer probe and a vacuum pump which are connected to each other by a gas flow path, a gas analyzer arranged along the gas flow path and analyzes the gas taken in by the vacuum pump through the sniffer probe. The sniffer leak detector further includes a distance sensor that detects the distance between the sniffer probe and the test object, and a control is linked to the distance sensor. The control is designed to vary the carrier gas flow transported along the gas flow path, depending on the measured distance.
