Presenting the W301 2.0 Gravimetric Method Water Vapour Permeability Analyser, built upon the gravimetric method (weight loss) testing principle. Meticulously crafted in adherence to standards such as GB/T 1037, ASTM E96, and more, this analyser is tailored for the water vapour transmission performance assessment of films, sheets, paper, packaging, and related materials across diverse industries including food, medicine, medical equipment, daily chemicals, and photovoltaic electronics. Offering a wide-range, high-efficiency water vapour transmission rate detection, it caters to high, medium, and low water vapour barrier materials.

Test Principle Distilled water is added to the clean moisture-permeable cup, sealed with a pre-treated sample, and placed in the test chamber. By controlling temperature and humidity, the analyser measures the weight loss of the distilled water over time, deriving parameters such as the sample's moisture permeability.

Standards GB/T 1037, GB/T 16928, ASTM E96/E96M, ASTM D1653, TAPPI T464, ISO 2528, DIN 53122-1, JIS Z0208, YBB 00092003
