Oxygen Permeability Instrument

oxygen permeability instrument is applicable in oxygen permeability test of plastic films and packaging containers(such as plastic bottles and plastic packages) in air or in 100% oxygen.
1. Characteristics
· Equal-pressure principle which is more like actual of production.
· High resolution, accurate test data.
· Two test models of such as package and film, and easy to change.
· Professional software, perspicuous test course.
· Test data is stored forever, easy to search and compare.
· Users can get other gas permeation data by Labthink?s technical support. Multifold functions in one.
· Employs best elements in the world, steady and reliable running.
· LCD shows test parameters, friendly human-equipment interaction design.
· Keep running while power down, free from the interference of power down.
· Compatible with ISO, ASTM and various oxygen transmission test standards.
2. Principle
High pure oxygen flows on one side of the film, high pure nitrogen flows on the other side of the film. Oxygen molecule passes the film into the nitrogen of another side, and is taken to the sensor by the flowing nitrogen.
Test the transmission of oxygen by analyzing the concentration of oxygen detected by sensor. As for packaging container, nitrogen flows in the container, air or high pure oxygen covers the outside of the container.
3. Standard
ASTM D3985, ASTM F1307, ASTM F1927, ISO 15105-2, JIS K7126-B
