The OX-TRAN® 2/61 is the most recent addition in permeation test systems for measuring oxygen transmission rates of barrier films and packages. The OX-TRAN 2/61 detects and measures small amounts of oxygen as it passes through barrier materials such as plastics and composites used in all forms of packaging. Ideal systems for production and QC/QA testing applications. This system incorporates the latest in high-sensitivity sensor design and features 6 test cells for flexibility and speed. Includes precise RH & temperature measurement and control, user selectable sensitivity, package testing capabilities and N.I.S.T. (National Institute of Standard and Technology) traceable calibration films.
