A bench-top version of the first-ever unit to measure both residual headspace oxygen (O2) as well as absolute package leak rate is being introduced by Mocon, Inc. Pac Check® Model 840 Package Integrity Test System, follows on the heels of the hand-held Pac Check® Model 820 introduced last year. The bench-top model was engineered in response to customer requests for a more robust unit with a powerful pump for faster test results. Along with the oxygen headspace reading, the bench-top Pac Check® Model 840 Package Integrity Test System calculates the real and accurate leak rate of a package. The system produces an absolute leak number based on the application of Poiseuille’s law which yields a total “hole” diameter leak size based on measurements of pressure and flow. The impact to packagers is that they will now be able to measure in one quick analysis, two critical variables which determine package shelf-life.
