Water Vapor permeation teste

W301

Function and usage

W301 Water Vapor permeation tester tests the water vapor transmission rate (WVTR) of packaging material. This instrument is widely used in food industry, pharmaceutical industry, cosmetics flexible packaging materials industry (plastic film, barrier materials, sheets metal aluminum, PVC,PVC sheets), college, university and quality institution for their water vapor transmission rate (WVTR) test and quality control.

It carrier the standard of GB 1037-1988 , GB/T 16928-1997, ASTM E96-00e1, ASTM D1653-03, TAPPI T464.ISO2528.

 

Working Principle

W301 Water Vapor Permeation Tester was designed with principle of weighting method to use weight reduction method to rest the water transmittance rate (WVTR) of plastic films. Namely in the regulated temperature, relative humidity conditions, the sample two sides keep the vapor different pressure, measuring the vapor volume passed through, figure out the WVTR value, Unit is g/m2+24h.
