Helium Leak Testing Services 

Our leak tester is calibrated before each test session and is traceable to MIL and ASTM standards.


  1. Certification stating the model and serial number of the leak tester.
  2. The results of the test and/or leak rate for each item. 
  3. The calibration parameters performed before each test session.

Standard vacuum and “bomb chamber” testing are available.
