Leak Testing Equipment With Helium Trace Gas For Auto Part Pipeline
What is helium leak testing?
Helium leak testing is used to find small leaks or larger leaks in bigger volumes. The helium is used as a tracer gas and its concentration is measured. This guide to helium leak testing should outline the basics of using this leak testing method.
Helium Leak Testing features are:
1. Most sensitive (1 x 10-6)
2. Independent of temperature
3. Independent of volume
4. High throughput
5. Most expensive
6. Most complex
HeJin's proprietary vacuum chamber system judges tiny leaks with an accuracy 100 to 1000 times as high as the accuracy of a submerged type or differential pressure air leak detection method. Leak Testing Equipment
