Sniffing leak detector including a handheld device with a sniffer tip probe including a sample gas inlet, a reference gas inlet, a gas analyzer, and a switching valve adapted to alternatingly connect the sample gas inlet to the gas analyzer and the reference gas inlet to the gas analyzer in a gas conducting manner, such that either the gas drawn through the sample gas inlet or the gas drawn through the reference gas inlet is analyzed by the gas analyzer, characterized in that the reference gas inlet is arranged in a remote distance from the sniffer tip probe and a reference gas conduit connecting the reference gas inlet and the switching valve includes a buffer chamber adapted to homogeneously mix gas drawn into the buffer chamber through the reference gas inlet with the remaining gas in the buffer chamber.
