1. Introduction
Oxygen permeability test.
Films, sheets, plates, containers made of plastic, fabric, leather, metal, etc.
2. Working principle
Coulomb electric method.
Certain humidity or dry oxygen flows on one side of the material, and high-purity nitrogen (carrier gas) flows at a fixed flow rate on the other side; the difference in oxygen concentration on both sides of the sample drives oxygen to permeate from the oxygen side of the sample to the nitrogen side; The permeated oxygen is carried by nitrogen (carrier gas) to the coulometer trace oxygen sensor; the sensor measures the oxygen content of the carrier gas and calculates the oxygen permeation volume of the sample and other parameters.
3.Executive standard
YBB 00082003、GB/T 19789、ASTM D3985、ASTM F2622、ASTM F1307、ASTM F1927、ISO 15105-2、JIS K7126-B
4. Product features
