Water Vapor Permeability Analyzer

PKT-W533 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
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.
