Working Principle
Desiccant Method. Test sample separates test chamber into upper room and lower room; humid gas flows in upper room, and place desiccant device in lower room; as water molecules penetrate through the sample from upper room into lower room and absorbed by desiccant, the cup weight will increase; weigh the cup and calculate water vapor transmission rate.

Standards
GB 1037, GB/T 16928, ASTM E96, ASTM D1653, ISO 2528

Features

  • Three chambers, each with independent sensor and test data; can test three samples at the same time.
  • High precision sensor, continuous weighing and data acquisition.
  • Automatic test, auto judgment, auto stop.
  • Built-in operation system, can test independently without computer.
  • LCD screen, Windows style interface, real time display test data; operate by mouse, easy to use.
  • Advanced electromagnetic temperature control technology, program controlled, auto increase and decrease; integrated design; precision 0.1℃.
  • Double gas flow (wet gas and dry gas) method to control humidity; integrated design, no external accessary.
  • High precision, can test aluminum foil.
  • Sensor over range protection.
  • Can expand to up to 10 test chambers.
  • Profesional software, simple interface, easy to use.
  • Real time display curves of transmission rate, weight, humidity, temperature.
  • Can zoom and move curves freely, so as to make detail analysis.
  • Professional test report, can export file in Office, PDF format etc.
  • Calibrated by Standard Film or standard weight.
