Isn’t Pressure Decay Leak Testing Always the Lowest-Cost Method? LeanPass™

Answer: No! Pressure Decay Test Methods Can Raise Costs Up to 50%!

  • Many make the mistake of equating the upfront costs of a leak tester instrument with the costs of the leak testing in total. Over the economic life of a leak tester, the upfront costs of the test instrument are a mere fraction, often trivial, of the overall testing costs.
  • Pressure-decay leak testing is difficult because measurements are highly vulnerable to changes in testing conditions such as drafts or temperature and there are often difficulties in determining the volume of test parts and test circuits, which must be known in order to calculate results. Also, pressure decay methods, including differential pressure decay methods, have hidden costs that derive from the need to make two measurements and then correlate results to determine a leak rate. Two measurements mean double the chances for measurement error. In addition, the longer the interval between the two measurements the higher the probability for measurement error – especially for leak testing large volume parts.
  • The problems inherent in pressure decay can be avoided by using an InterTech M1075 with LeanPass™ to achieve a cycle time reduction of up to 50%.
