How to Choose an Air Leak Tester ?

How to Choose an Air Leak Tester

The most important factor to consider when choosing an air leak testing device is the acceptable leak rate of the tested part or vessel. The largest influence on the acceptable leak rate is the media that must be retained—is it liquid/fluid or gaseous? Air, for example, will pass through a leak path up to 300 times faster than water will travel that same path. Standard non-water (air or gas) leak rates are generally between 1-5 scc/min (standard cubic centimeters per minute), though sometimes as high as 10 scc/min.
 
The other key factor in selecting an air leak tester is that the device must be capable of supplying at least 100 times greater resolution than the leak rate being measured.
