Test Principle
Based on gravimetric determination method, under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the test dish in different time, water vapor transmission rate and other parameters can be obtained.

Applications

Basic Applications	Primary Wound Dressings	Various medical tapes, surgical films, wound dressings, silicate dressings, silver ion dressings, hydrogels, wound care materials, PU films
	Textiles and Nonwovens	Suitable for water vapor transmission rate test of textiles and non-woven materials
	Daily Necessities	Suitable for water vapor transmission rate test of various facial masks, wet wipes, diapers and sanitary napkins
Extended Applications	Inverted Cup Method	Mount film or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate. NOTE: inverted cups are required
