The OX-TRAN 2/22 series of 1-cell high-performance analyzers can test the oxygen transmission rate (OTR) on both films and packages from low- to moderate-level barriers. These lower-cost analyzers for packages and films are easy to use and offer the shortest test times available in the market. They feature 1 changeable horizontal test cartridge that allows a wide variety of sample sizes and types to be easily and accurately tested.
Highest Accuracy
- Patented COULOX® sensor is the only absolute Coulometric sensor on market, never requiring calibration
- Low detection levels available down to 0.05 cc/(m2 × day) (H model)
- Fully automated temperature, flow and RH controls simplify testing and provide unparalleled repeatability
Easy to Use
- Industry-fastest sensor response time allows shorter overall test times
- Removable test cartridge allows easy sample preparation on the bench
- Automated test method can start a test by a single press of a button
- TruSeal® gas flushed perimeter sealing reduced background levels for more accurate test results
The 2/22 Series uses MOCON’s patented COULOX absolute (intrinsic) coulometric sensor requires no calibration and is the base for the ASTM standard
D3985. It is the only instrument family proven to meet its precision and bias requirement through independent and 3rd-party testing.
MODELS:
This family of highly accurate instruments has 2 models having a different lower detection limit.
- A Model (low barriers) - able to test common barriers providing a range from 0.1 to 200 cc/(m2 × day)
- H Model (moderate barriers) - the most popular detection range from 0.05 to 200 cc/(m2 × day)
Their upper detection limit of 200 cc/(m
2 × day) can be extended with the use of the
reduced area film test cartridges, atmospheric oxygen in place of the normal 100% O
2 (factor of 4.8) or various size masking. The series has industry leading features such as removable and interchangeable horizontal test cartridges, easy to use touchscreen operator interface, and fully automated testing providing higher throughput in the lab.
For more than 25 years, MOCON’s OX-TRAN series of instruments have been the most trusted and longest lasting on the market. From simple single layered barriers to complex multi-layered barriers, the OX-TRAN 2/22 series is the right choice.
Removable Cartridges

Standard Test Method for Oxygen Gas Transmission Rate Through Plastic Film and Sheeting Using a Coulometric Sensor
The test specimen is mounted as a semi-barrier between two chambers at ambient atmospheric pressure. One chamber is slowly purged by a stream of nitrogen and the other chamber contains Oxygen. As Oxygen permeates through the film into the nitrogen carrier gas, it is transported to the coulometric detector where it produces an electrical current, the magnitude of which is proportional to the amount of oxygen flowing into the detector per unit of time.
