OX-TRAN® 2/20 Detects and measures extremely small amounts of oxygen as it passes through barrier materials such as plastics and composite materials used in all forms of packaging. OX-TRAN systems enable you to measure the effects of temperature and relative humidity on high-barrier material films and packages. Using a patented sensor, this system provides parts-per-billion sensitivity even in the presence of water vapor. Ideal for deciding how thick and what barrier material will best suit your project. Use it for incoming QC to measure vendor compliance with your specifications. All test results are documented by sophisticated, yet easy to use software that provides graphs, tables, and numerical listings. In addition to barrier oxygen transmission testing, another configuration of the "2/20" is designed to measure high transmission rates to accommodate the fresh-cut produce packaging market. Create the testing environment you need by choosing from a variety of system configurations that fit your budget today while enabling you to expand your system in the future. OX-TRANs Master Module designs let you choose the level of sophistication you need, while add-on "satellite" testing stations let you boost test cell capacity when you need it. You can link up to 20 of these modular test cells together for unmatched flexibility.
