Principle
The pre-conditioned specimen is mounted between the upper and lower chambers at ambient atmospheric pressure. The upper chamber contains oxygen or air and the lower chamber is slowly purged by a stream of nitrogen. Due to the concentration difference between the two chambers, oxygen molecules permeate through the specimen into the nitrogen side and are taken to the coulometric sensor where proportional electrical signals are generated. The oxygen transmission rate is then obtained by analyzing the signals and calculating the volume of oxygen measured by the sensor. For whole package samples, high purity nitrogen flows inside the package, and oxygen or air flows outside.
Standards
This test instrument conforms to the following standards:
ISO 15105-2, ASTM D3985, ASTM F2622, ASTM F1307, ASTM F1927, GB/T 19789, JIS K7126-2, YBB00082003
This instrument is applicable to the determination of oxygen transmission rate of:
| Basic Applications | Films
Including plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminized films, aluminum foil, aluminum foil composite films and many others |
|---|
Sheeting
Including various sorts of engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC |
Packages
Including plastic, rubber, paper, paper-plastic composite, glass and metal packages, e.g. Coke bottles, peanut oil packages, Tetra Pak materials, vacuum bags, metal three-piece cans, plastic packages for cosmetic, soft tubes for toothpaste, jelly and yogurt cups |
| Extended Applications | Package Caps
Test seal performance of different package caps |
|---|
Solar Back-Sheets
Including solar back-sheets |
Plastic Pipes
Including various sorts of pipes, e.g. PPR |
Blister Packs
Test oxygen transmission rate of the whole blister packs |
Fuel Tanks of Cars
Plastic fuel tanks are widely used in cars for its light weight, buffering vibration and easy molding characters. But its fuel permeability is the most essential factor, this instrument can be used to test permeability of plastic fuel tanks |
Battery Plastic Shell
Battery electrolyte is protected by the plastic shell from outside environment. Battery service life is directly dependent on its oxygen permeability. This instrument can be used to test oxygen transmission rate of battery plastic shell |
Red Wine Bottles
Test oxygen transmission rate of red wine bottles |
Features
Automatic test mode achieves “One-key start” after sample mounting.
User doesn’t need to have professional materials knowledge, doesn’t need to have skilled instrument operation experience, doesn’t need to set many control parameters. Labthink patented Coulometric oxygen sensor
The detection limit, precision and repeatability of fully absorbed oxygen sensor is better than partially absorbed oxygen sensor.Reliable and easy-to-use control system
The C203H is controlled by a Windows based touch screen tablet and a set of embedded industrial computer, which makes instrument control more user friendly and better reliability No need to use Mask to reduce the test area, no need to use low-concentration oxygen, you can achieve ultra-low barrier material testingMulti-sensor technology: It can be equipped with different ranges oxygen sensors, which can be automatically switched according to the barrier properties of the sample to meet the test of high, medium, low, and ultra-low barrier materials (custom model)Operational safety: The test chamber is automatically opened/closed at smooth speed without impact.Instrument safety: having temperature over-limit alarm, automatically cut off the temperature control
