Presenting our Gravimetric Method Water Vapour Permeability Analyser AUTO W812, meticulously crafted based on the cup method water vapor transmission test principle, and designed in compliance with ASTM E96, GB/T 1037 standards.

This advanced analyser offers extensive and efficient water vapour transmission rate detection for low, medium and high water vapor barrier materials. Ideal for applications in food, medicine, medical equipment, daily chemicals, and more, it caters to the water vapour transmission performance testing of films, sheets, paper, fabrics, non-woven fabrics, and related materials.
