Helium Leak Detector

iitk.ac.in/ibc/HLDr.pdf

Helium Leak Detector Why use helium for leak detection? Helium is the best choice to find leaks because it is non-toxic, inert, non-condensable, non-flammable, present in the atmosphere in trace amounts (5 ppm). Due to its small atomic size, helium passes easily through leaks. The only molecule smaller than helium is hydrogen which is not inert.

Detection technique. Helium is used as a tracer because it penetrates small leaks rapidly. Helium has also the property of being non-toxic, chemically inert and present in the atmosphere only in minute quantities (5 ppm).Typically a helium leak detector will be used to measure leaks in the range of 10 −5 to 10 −12 Pa·m 3 ·s −1.. A flow of 10 −5 Pa·m 3 ·s −1 is slightly less than ...
