Helium Leak Testing Equipment For Automobile Parts Tracer Gas Method
Feature:
Systems include sniff leak testing, nitrogen purge leak testing, accumulation tracer gas systems, and hard vacuum helium leak tests. Tracer gas leak detection systems provide high sensitivity, accuracy and repeatability and can be used to test parts with extreme leak rate requirements.
Benefits of Tracer Gas (Helium) Leak Testing:
Enhanced sensitivity and resolution for increased leak test accuracy
Capability to detect micro-leaks down to 1x10-9 scc/s (0.0000000001 scc/m)
Faster test times than air-flow leak testing technology
Non-temperature dependent test accuracy
Significantly reduces false leak failures
Helium is the most commonly used tracer gas for leak detection
The tracer gas method can be used for both leak location and small leak detection
