LACGircinoiocies HELIUM SNIFFER PROBES HELIUM SNIFFING TIPS When using a helium sniffer probe to test pressurized components or system ensure that there are no gross leaks in the system prior to pressurizing Gross leaks will allow the surrounding air or background to become contaminated with helium which lowers the sensitivity of the leak test When venting helium from a pressurized test part do not vent in the same area where the testing is performed This will contaminate the surrounding air with helium When the ambient air is contaminated with helium a large fan can be used to exhaust the test area and provide clean air When sniffing a part with multiple potential leak locations always begin sniffing near the bottom of the part and work towards the top It may be necessary to repair leaks that are found before proceeding Helium escaping from the part will rise and can give a misleading leak location PROCEDURE 1 Connect Sniffer probe to Sniffer or inlet Test Port for the leak detector you are using Refer to the leak detector user manual for instructions Sniff leak test per the leak detector user manual instructions While testing do not plug or contaminate the sniffer probe tip If the probe becomes plugged or dirty remove the clear tube and filter assembly from the tip Replace with a spare unit supplied with the sniffer probe Slide the clear tube over the stainless steel tube s
