Oxygen Transmission Rate Testing for Production Plants

The Mocon OX-TRAN 2/28 is a fully automated, stand-alone oxygen transmission rate (OTR) instrument designed for routine analysis of medium- to high-barrier films in labs with high-throughput testing requirements.

The Best Just Got Better

Building on the legacy of the world-renowned OX-TRAN 2/21, the 2/28 features automatic control of flow, pressure, and temperature, along with removable test cells for quick and easy sample handling. Innovative Tru-Seal technology ensures airtight testing conditions, preventing outside air from affecting results.

Unparalleled Quality and Reliability

Each OX-TRAN is factory-standardized to deliver consistent, accurate results regardless of operator or location. Using market-leading NIST-traceable reference films, you can continuously verify performance and maintain confidence in reproducible, repeatable measurements.

Eliminate Calibration Error

The 2/28 uses reference (not calibration) films, because calibration isn’t needed. Its proprietary Coulox® sensor measures every oxygen molecule transmitting through the sample and displays results in your preferred units. Reference films simply confirm that the system is performing correctly.
