Gravimetric Method Water Vapor Permeability Analyzer AUTO W806

Test principle

Desiccant (weight gain method) or place water (weight loss method) in the sample cup; seal the sample cup with the sample and place it in the test box; control the temperature, humidity and wind speed of the test box; The difference in humidity drives the water vapor to penetrate the sample, and the mass of the sample cup increases or decreases; the mass of the sample cup is regularly weighed, and the performance parameters such as the water vapor transmission amount of the sample are calculated.

Standard

ASTM E96, ASTM D1653, ISO 2528, TAPPIT464, DIN 53122-1, YBB00092003
