Permeameter OTR-D3

Product overview
OTR-D3 Oxygen Transmission Rate Tester is based on the coulometric sensor method and is designed to measure oxygen permeability of medium- and high-barrier materials such as plastic films, composite films, sheets and papers used in food, pharmaceutical, medical device, consumer and electronics packaging applications.

Features

• Coulometric sensor method with high precision infrared sensor to ensure measurement accuracy.
• Automatic humidity and temperature control to maintain a stable test environment.
• PC-controlled operation with dedicated testing software and user-friendly interface.
• Real-time display of test data and permeation curves.
• Three independent test chambers allowing simultaneous testing of 3 samples.
• One-button automatic test start for simplified workflow.
• Patented pipeline flushing design for carrier gas cleanliness and high testing efficiency.
• Leak-proof sample sealing technology to improve chamber sealing performance.
• Optional computerized data traceability and rights management for pharmaceutical industry compliance.

Testing principle
The pre-conditioned specimen is clamped in the test cell. Oxygen (or air) flows on one side of the specimen while high-purity nitrogen flows on the other side. Oxygen molecules permeating through the specimen are carried to the coulometric sensor, which analyses oxygen concentration and calculates oxygen transmission rate and related parameters.
