Function And Usage

Model Y201D Oxygen permeation tester test the high barrier materials, sheers, solar board, Compound materials, PVC, rubber, paper, glass, metal and such material 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 nether parts, the samples film is fixed between the two chambers, the high pure oxygen (O2) circulate in the upper chamber of the film, and high pure nitrogen (N2) circulate in the nether chamber of film, the oxygen molecules get through the film and spray to nitrogen in the in  the nether chamber, and brought by the following nitrogen to the sensor, and the tester then analyze the oxygen concentration as what the sensor tested and calculate the oxygen permeation quality. But for the packaging containers, the nitrogen circulates in the bottle and the air or oxygen circulates outside the container.
