PKT-W402 Water Vapor Permeability Analyzer tests the water vapor transmission rate of plastic film, composite film, aluminum foil, thin sheets, rubber, porcelain, solar panel, medical patch and so on.

 

Working Principle
Infrared detection sensor method. Test sample separates test chamber into upper room and lower room; humid gas flows in upper room and dry gas flows in lower room; water molecules penetrate through the sample from upper room into lower room; infrared detection sensor measure the water vapor density of lower room to calculate water vapor transmission rate.

Standards
GB/T26253, ISO 15106-2, ASTM F1249, TAPPI T557, JIS K7129

Features

  1. Two chambers, each with independent test data.
  2. Automatic test, auto judgment, auto stop.
  3. Built-in operation system can test independently without computer.
  4. LCD screen, Windows style interface, real time display test data; operate by mouse, easy to use.
  5. Advanced electromagnetic temperature control technology, program controlled, auto increase and decrease; integrated design; precision 0.1℃.
  6. Double gas flow (wet gas and dry gas) method to control humidity; integrated design, no external accessory.
  7. High precision can test aluminum foil.
  8. Can expand test range to 1000g/m2·24h. (optional)
  9. Can test packaging containers, such as bag, bottle, bowl etc. (optional)
  10. Sensor over range protection.
  11. Can expand to up to 12 test chambers.
  12. Professional software, simple interface, easy to use.
  13. Flexible setting of test process.
  14. Real time display curves of transmission rate, water vapor density, humidity, temperature.
  15. Can zoom and move curves freely, so as to make detail analysis.
  16. Professional test report, can export file in Office, PDF format etc.
  17. Calibrated by Standard Film.
