Test Principle
The oxygen gas transmission rate is determined after the sample has equilibrated in a dry test environment. In this context, a “dry” environment is considered to be one in which the relative humidity is less than 1 %.
The specimen is mounted as a sealed 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 gas 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 time.

Adopting state reference materials to calibrate and verify the instruments, ensure the accuracy, universality and authority of the test data.
Simple operation
● LCD and windows instrument interface show testing data and working status in real time; mouse operation is simple and convenient.
● Professional software with simple interface, easy to use and convenient to set test process.
● Fully-auto operation, judge and stop automatically.
● Real time curves display of transmission, oxygen concentration, temperature and humidity, curves can be easily zoomed and moved. The curves with conceal function, support query function for background data.
● Professional test report; can be exported as PDF.
Advanced technology
● Temperature control: International advanced electromagnetic technology, program controlled, auto heating and cooling; and no need of external accessories. Precision: 0.1℃.
● Humidity control: Dual gas flow method(dry gas and humid gas), with broad range, high precision (1%RH) and stable flow.
● Carrying cutting-edge ARM controlling system, can run independently without computer.
High efficiency
● Data is independent in three test chambers: Each chamber test independently, three same/different samples can be test at the same time and output three separate test reports, which improve the test efficiency, one set is worth three sets.
● Measurement precise up to 0.001 cm3/（m2·24h）, can test high barrier materials, such as aluminum foil.
● By adding package-testing accessories, can test oxygen transmission of various containers such as bag, bottle, can and bowl.
● By adding adaptive accessory, can expand upper limit of test range to 260000 cm3/m2•24h.
Calibration & Certification
● The instrument supports two methods of reference materials and standard gas to certificate and calibrate; Operation is simple, user only need use certified reference materials for normal testing, and then input the test result into the instrument interface to complete calibration.
Reliable and easy-maintenance instrument
● Imported oxygen sensor, with high precise and good performance, can work for a long time.
● Sensor over-range auto protection.
