Oxygen Permeation Tester 2

Function
and usage
Model 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•24) or ppm selected by the user.
