Product Description

Water Permeability Analyzer

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
