Leak Rates and Pressure- Pressure in Helium Leak Detection

When visiting production leak testing customers, everyone seems to have a good idea of their leak rate. I visit a lot of customers sniffing for helium and/or hydrogen. At these visits I ask them their leak rate specification and are commonly told " Our leak rate is 0.10 oz/yr of R410A".

Apr 02, 2018Helium is one of the best-suited choices to find the leaks because it is non-toxic, inert, non-condensable, non-flammable and is present in the atmosphere in the trace amounts (5 ppm). Since the atomic size of the helium is small it easily passes through the leaks. Hydrogen is the only molecule smaller than helium. Hydrogen is not used in leak detection because it is not inert.
