1. Temperature control: International advanced electromagnetic technology, program controlled, without external accessories. Precision 0.1°C.
2. Humidity control: Two-way gas flow method, with broad range, high precision and stable flow.
3. Standard gas calibration and standard film calibration.
4. Auto judgment and auto stop.
5. Leakage protection; over range protection; auto save data when power is cut off; incorrect operation warning.
6. Wholly automatic, software easy to use. Curves of transmission rate, oxygen density, humidity and temperature, auto record and continuous display. Can monitor interaction of parameters and the whole testing process.
7. Highly modularized. Setting, testing, baseline, calibration, report etc are independent. Powerful data analysis. Easy to operate.
8. Built-in computer, can work without external computer.
9. Support quick test, applicable to evaluation test.
10. Two chambers can work independently at the same time for two different samples.
To test the oxygen transmission rate (OTR) of packaging materials, such as plastic film, composite film, coextrusion film, aluminum-plated film, aluminum foil, infusion bag, sheets, paper, paper board, solar battery panel, cellophane, ceramics and porcelain, and various containers such as bag, pouch, bottle, can, bowl, box, widely used in the industries of food, pharmaceuticals, personal care, household, electronics and so on.
Coulometric sensor method. Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room. When oxygen flows in upper room and nitrogen in lower room, the oxygen molecules penetrate through the sample into the lower room, and coulometry sensor system detect and analyze the oxygen content and calculate the oxygen transmission rate. To test container, oxygen is outside and nitrogen is inside of the container.
