Principle
The preconditioned specimen is mounted between the upper and lower chambers. One chamber contains oxygen or air and the other chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side, and are then carried to the sensor. The oxygen transmission rate is then obtained by analyzing the oxygen concentration measured by the sensor. For package samples, high purity nitrogen flows inside the packages, and oxygen or air flows on the outside.
Standards
This oxygen permeability tester conforms to the following standards:
ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, ISO 15105-2, GB/T 19789, JIS K7126-2, YBB 00082003
This oxygen permeability tester is designed for oxygen transmission rate test of:
| Basic Applications | Films
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foils, aluminum composite films, and many others |
Sheeting
Including various sorts of engineering plastics, rubber, and building materials, e.g. PP, PVC and PVDC |
Packages
Including plastics, rubber, paper, paper-plastic composite, glass, and metal packages, e.g. Coke bottles, peanut oil packages, Tetra Pak materials, vacuum bags, metal three-piece cans, plastic packages for cosmetic, soft tube for toothpaste, jelly and yogurt cups |

Fuel Tanks of Cars
Plastic fuel tanks are widely used in cars for its light weight, buffering vibration and easy molding characters. But its fuel permeability is the most essential factor. This instrument can be used to test permeability of plastic fuel tanks |
Battery Plastic Shell
Battery electrolyte is protected by the plastic shell from outside environment. Battery service life is directly dependent on its oxygen permeability. This instrument can be used to oxygen transmission rate of battery plastic shell |
Red Wine Bottles
Test oxygen transmission rate of red wine bottles |
Functionality
Two test modes for films and packages (accessories for package test are optional) Wide range and high precision temperature and humidity control, as well as dual-side humidification of the specimen, support various combinations of non-standard test conditions World leading pressure compensation technology ensures accurate and repeatable test results Standard, proportional and continuous testing modes provide suitable test method for different materials Equipped with catalyst deaerator to purify carrier gas and reduce system errors 2 types of carrier gases are available: high purity nitrogen gas or hydrogen-mixed nitrogen gas Convenient fast access port for temperature and humidity Reference film or standard gas for fast and accurate calibration Design
Patented integrated design of three test cells improves the test efficiency and reduces the space occupancy of the instrument. 3 distinct or identical specimens could be tested simultaneously with individual test results.The system can be easily connected with a maximum of 9 satellite bases to accomplish up to 30 tests at the same time. Oxygen and water vapor transmission rate can be obtained at one operation by working with Labthink’s water vapor transmission rate test system together under the control of one master base. Embedded computer control system provides safer and more reliable data management as well as test operation. The oxygen permeation analyzer can be easily operated with a mouse, a keyboard, and a monitor, without requiring a PC. The oxygen permeability tester is equipped with four USB ports and dual Internet ports for convenient data transmission. Sophisticated energy consumption and test environment monitoring and analysis functions for better test accuracy and reliability. (Relevant sensors are needed. For more information, please refer to the configuration in Technical Specifications.) Universal power input for easy access. Software
Interface: Windows-based operating interface Statistics: easy calculation for historical results, instrument usage, energy consumption, and large statistical information Data Comparison: by presetting target value and range, the system automatically generates data comparison after each test and intelligently judges whether the specimen passes or fails the test Test Report: can provide detailed test reports in various customized patterns Energy Consumption and Test Status Monitoring (Additional Sensors Required): the system monitors and displays real-time voltage, current, energy consumption of instrument as well as ambient temperature and relative humidity during the test, which serves to evaluate test data reliability User Management: multi-level account management for better data management and protection Operation Log: system automatically records all the operations by the user, which is easy to review
