Water Vapor Permeability Analyzer

Working Principle
Water Method. Hold water in cup sealed by test sample; outside the cup remains dry by desiccant; as water molecules penetrate through the sample from inside the cup to outside, the cup weight will decrease; weigh the cup and calculate water vapor transmission rate.

Standards
ASTM E96, ASTM D1653

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 displaytest data; operate by mouse, easy to use.
• Advanced electromagnetic temperature control technology, program controlled, auto increase and decrease; integrated design; precision 0.1℃.
• High precision, can test aluminum foil.
• Can test packaging containers, such as bag, bottle, bowl etc. (optional)
• Sensor over range protection.
• Can expand to up to 12 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.
