Reference leakage device for leak sniffer detector

The invention concerns a reference leakage device ( 14 ) for leak sniffer detector ( 1 ) equipped with a sniffing tip ( 8 ) and a control unit ( 6 ). Said reference leakage device ( 14 ) comprises a gas reservoir ( 31 ) and a constriction ( 33 ) wherefrom there is released a specific amount of test gas, at least during calibration. The reference leakage device ( 14 )4) is characterised in that in the constricted zone ( 33 ) there is located a sensor ( 42 ) detecting the approach of the sniffing tip and in that said device includes means for transmitting signals to the control unit ( 6 ) of the leak detector. 4) Translator's note: The German text states " 1 " here whereas " 14 " would be more in line with the drawing figures and the remaining text. Therefore the " 14 " has been assumed for the translation.
