Gravimetric Method Water Vapor Permeability Analyzer AUTO W809 Introduction This product is based on the test principle of cup method water vapor transmission, and is designed and manufactured according to ASTM E96 standard, and provides a wide range and high efficiency water vapor transmission rate detection for low, medium and high water vapor barrier materials testing. It is suitable for the water vapor transmission performance test of films, sheets, paper, fabrics, non-woven fabrics and related materials in the fields of food, medicine, medical equipment, daily chemicals, etc. 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.
