Mocon's PAC CHECK Model 333 hand-held headspace analyzer measures carbon monoxide levels in modified and controlled-atmosphere case-ready meat packaging. The unit also measures oxygen and carbon dioxide levels. To provide headspace analysis of finished packages, the unit offers a Sticky Foot probe, which houses the needle internally for protection. The needle is actuated by twisting the outer housing, which allows it to penetrate the package and measure internal gas levels.
