Advantages of SF6 End-of-life check for leaks

A tracer gas leak test can be used to test parts with very low leak rates that are outside the range for conventional air-flow pressure decay and mass flow testing, or to replace bubble test methods. The tracer gas leak test uses escaping tracer gas to identify micro-leaks in the range of 1x10 -4 to 10 -9 scc/s.
