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 application	Film	Plastic films, plastic composite films, paper-plastic composite films, coextruded films, aluminum coated films, aluminum foil composite films, glass fiber aluminum foil paper composite films and many other film materials
	Sheeting	PP, PVC and PVDC sheeting, metal foils, rubber pads and other sheeting materials
	Textiles and Non-woven	Textiles and non-woven fabrics such as diaper, sanitation products, etc.
	Paper and Paper Board	Aluminum coated paper for cigarette, paper aluminum plastic composite film and other paper and paper boards
Extended application	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
	Artificial Skin	Artificial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance. This instrument can be used to test water vapor permeability of artificial skin
	Cosmetic	Water vapor permeability of cosmetics
	Aseptic Films	Aseptic wound protecting films, medical plasters and protective clothing materials
	LCD Display	Water vapor transmission rate of LCD display and its relevant sheet
	Solar Back-sheets	Water vapor transmission rate of solar Back-sheets and its relevant sheet
	Paint Film	All types of paint films
	Biodegradable Films	Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films
