Non-Destructive Leak Detection

The machine works by placing a package between two membranes to create a vacuum, and then measures the change in pressure to identify leakage rates.


INFICON (Syracuse, NY) recently unveiled their Contura S400 leak detector with features that include:

  • A non-destructive testing approach that the company feels is more reliable than water bath testing.
  • Designed for food applications that include coffee, meat and poultry, baked goods, snack foods, confectionery/candy, cheese, grains and cereals, prepared food and produce that are contained in Modified Atmosphere Packaging (MAP) and flexible packaging.
  • Works by placing the package between two unique membranes that create a conformal vacuum chamber that is quickly evacuated. Air flows through any package leaks and into the chamber where it causes an increase in pressure.
  • A patented high precision vacuum gauge measures this change to calculate the package’s leak rate, delivering results in seconds.
  • The ability to detect micro and gross leaks, eliminating risks from a package with a tear or a non-welded sealed seam that might be incorrectly identified as airtight.
  • Works independent of gas.
  • A stainless steel housing and dirt-resistant protective cap.
