OX-TRAN® Model 1/50

Oxygen Transmission Rate (OTR) Testing and ASTM D3985 Compliance

The OX-TRAN® Model 1/50 enables an operator to determine the oxygen transmission rate (OTR) of flexible barrier materials for product packaging or industrial application. Key factors such as the thickness of the material and environmental factors such as relative humidity and temperature help to understand material permeability, making accurate testing data essential.

At MOCON our OX-TRAN® Model 1/50 OTR test system is designed for low-cost oxygen permeation rate testing with single cell flat films. Only MOCON instruments comply with ASTM D3985, a standard requiring the test procedure be done with a coulometric sensor to measure any oxygen being transmitted through material.

The Benefits of OX-TRAN® Model 1/50 for OTR Test Needs

As an oxygen permeation rate testing device, the OX-TRAN® Model 1/50 has easy film placement with lift out test cell capabilities. Pretest preparation is also available with additional cells.

Our oxygen transmission rate testing system has automatic humidity control and built-in software with product memory capability that allows you to customise and store up to 99 test methods. It has a bright, easy to read display and an advisory screen that prompts operator input.

The OX-TRAN® Model 1/50 also has a built-in system that protects against over or under pressure and system protections to avoid thermal runaway while in use. It requires no calibration and no flow adjustment, making it an OTR test system requiring no need for extensive training for staff. With pneumatic clamping, it is designed to be practical and efficient to use.
