W3/030 Water Vapor Permeation Analyzer is for the water vapor permeation rate measurement of plastic films, laminated films, sheets as well as various materials used in medical and construction industries. Through water vapor permeation rate testing, the demands for control and adjust technical indexes and satisfy.
This instrument confroms to the followting standards:
ASTM E96: Standard Test Methods for Water Vapor Transmission of Materials
ASTM D1653: Standard Test Methods for Water Vapor Transmission of Organic Coating Films
ISO 2528: Sheet materials -- Determination of water vapour transmission rate -- Gravimetric (dish) method
TAPPI T464: Water Vapor Transmission Rate of Paper and Paperboard at High Temperature and Humidity
Water Vapor Permeation Analyzer Principle
A specific humidity difference is formed among the two sides of the specimen under a certain temperature. The water vapor permeates through the specimen and into the dry side. By measuring the weight changes of the cup, water vapor transmission rate and other parameters can be obtained.
