Oxygen Transmission Tester
Oxygen Transmission Tester
Ensure the integrity of your packaging and materials with our high precision OTR tester, engineered to deliver unmatched accuracy in measuring oxygen permeability across films, membranes, and barrier packaging.
Test Principle
The principle of coulomb quantity method is adopted in this user-friendly interface OTR Tester . The pre-treated sample is fixed in the middle of the test chamber, high-purity oxygen flows in the upper chamber of the film, high-purity nitrogen (carrier gas) flows in the lower chamber, oxygen molecules are diffused through the film to the nitrogen on the other side, and the flowing nitrogen is carried to the sensor, and the oxygen transmission rate is calculated by analyzing the oxygen concentration measured by the sensor.

Product Feature And Application
Medical packaging gas permeability suitable for industries demanding rigorous quality control, including in food packaging, pharmaceuticals, medical devices, and sustainable material industrial.
Production Details
1.Based on the Coulometric /Equal Pressure Methodology, oxygen transmission is calculated via a current generated in proportion to the oxygen molecules penetrating the material.
2.The OTR tester's twin-chamber architecture-each with a precision oxygen sensor-facilitates simultaneous dual-sample testing, doubling efficiency in quality control labs.
3.Its wide dynamic range (0.005–1000 cm³/(m²·24h)) and sub-ppm resolution, paired with intelligent environmental controls, deliver industry-leading precision and reproducibility.
4.An internal deoxygenation tower actively scrubs the carrier gas of oxygen contaminants, ensuring baseline stability for reliable data integrity.
