GBPI Water Vapor Permeability Analyzer W203 Working principle
W203 Water Vapor Permeability Tester Adopt Electrolytic detection sensor method. Fix the test sample in the middle of test chamber to separate the chamber into upper room and lower room. When humid gas flows in upper room and dry gas in lower room, the water molecules in upper room penetrate through the sample into the dry gas, and electrolytic sensor system detect and analyze the water content and calculate the water vapor transmission rate
W203 Water Vapor Permeation Tester Features
1. Wholly automatic, software easy to use. Curves of transmission rate, water vapor density, humidity and temperature, auto record and continuous display. Can easily monitor interaction of parameters and the whole testing process.
2. Highly modularized. Setting, testing, baseline, calibration, report etc are independent. Powerful data analysis. Easy to operate.
3. Built-in computer, can work without external computer.
4. Temperature control: International advanced electromagnetic technology, program controlled, no need of external accessories. Precision 0.1℃.
5. Humidity control: Dual gas flow method, with broad range, high precision and stable flow.
6. Standard gas calibration and standard film calibration.
7. Auto judgment and auto stop.
8. Leakage protection; over range protection; auto save data when power is cut off; incorrect operation warning.
9. Support quick test, applicable to evaluation test.
10. W203 Water Vapor Permeability Analyzer equipped with two chambers ,can work independently at the same time for two different samples.
11. Software upgrade, data backup and fault diagnosis through USB port.
