Y201D Oxygen permeation tester tests the high barrier materials, sheets, solar board, compound materials, PVC, rubber, paper, glass, metal and such materials of bottle, blood bags for their oxygen transmission rate(OTR value)
Y201D Oxygen permeation tester tests the high barrier materials, sheets, solar board, compound materials, PVC, rubber, paper, glass, metal and such materials of bottle, blood bags for their oxygen transmission rate(OTR value) .
This instrument is widely used in food industry, pharmaceutical industry, cosmetics, flexible packaging materials industry and college, university and quality institution for permeation rate test and quality control.
It carries the standard of GB/T 19789-2005,ASTM D 3985-1995,ASTM F 1927-1998,ASTM F 1307-1990,YBB00082003,ISO 15105-2003,DIN 53380-3-1998,JIS K-7126.
Working principle
It adopts Coulometry theory, use the high precision sensor to test the oxygen transmission rate (OTR) of flexible packaging materials.
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 flowing nitrogen to the sensor, and the tester then analyze the oxygen concentration as what the sensor tested and calculate the oxygen permeation quantity. But for the packing containers, the nitrogen circulates in the bottle and the air or oxygen circulates outside the container. OTR unit is cm3 / （m2·24h）or ppm selected by the user
