A bench-top unit to measure both residual headspace oxygen as well as absolute package leak rate, Mocon’s Pac Check Model 840, produces an absolute leak number based on the applications of Poiseuille’s law, which yields a total “hole” diameter leak size based on measurements of pressure and flow. From these readings, further analysis can be done to set statistical parameters for acceptable product. Model 840 can save up to 240 data points in its internal memory. Information can also be sent to a computer via an RS-232 data line.
