Evacuation (Tracer Probe)
Pressurization (Detector Probe)
You NEED Helium Leak Testing When:
Conventional methods do not work
There are recurring leaks on repaired systems
The item needs to remain moisture free while out of service
Why Helium?
It is the lightest of the noble gases with a mass of 4 (only hydrogen is lighter)
It is non-toxic and non-reactive
Trace concentrations (5 ppm) present in atmosphere
Readily available and relatively inexpensive
