Introduction
This tester can be used to do high-precision oxygen permeability and water vapor permeability testing of film or sheet at the same time;
It adopts Coulometry theory for oxygen permeability test, and adopt international advanced electrolytic process theory for water vapor permeability test;
It is applicable for testing the oxygen transmission property and water vapor transmission property of plastic film, sheet and plastic bottles and bags etc. packaging containers in air or pure oxygen;.
Execution technical standard for oxygen permeability: GB/T 19789-2005, ASTM D 3985-1995, ASTM F 1927-1998, ASTM F 1307-1990, YBB00082003, ISO 15105-2:2003, DIN 53380-3-1998, JIS K-7126 ;
Execution technical standard for water vapor permeability: ASTM F1770, ASTM D1653-03, ASTM E96-00e1, ISO15106-3, JIS Z0208-1976, DIN 53122-1, ISO2528.
Testing principle
It adopts Coulometry theory;
The testing chambers including upper and nether parts, the sample film is fixed between the two chambers, the high pure oxygen (O2) circulate in the upper chamber of the film, and the high pure nitrogen (N2) circulate in the nether chamber of film, the oxygen molecules get through the film and spray to nitrogen in the nether chamber, and brought by the blowing nitrogen to the sensor, so, the tester then analyze the oxygen concentration as what the sensor tested and calculate the oxygen transmission value. But for the packing containers, the nitrogen circulate in the bottle and the air or oxygen circulate ouside the container
