Water Vapor Transmission Rate Analyser – Weighting Method
Standards:
ASTM E96-00e1 ,ASTM D1653-03, GB 1037-1988 ,GB/T 16928-1997, TAPPI T464,ISO2528.
Advantage:
High quality approved, the only testing instruments can be calibrated by standand gas in China.
Application :
* Films
rigid films, shrik films, stretch films, plastic films, plastic composite films, paper-plastic composite films,aluminized films, aluminum foil, aluminum composite films, high barrier films and many others. Eg. PET, OPP, CPP, LDPE, BOPP
* Sheet
engineering plastics, rubber, waterproof building materials, and thermal insulation materials, e.g. PP, PVC, PVDC, and nylon
*Packages
paper, plastics, rubber, paper, paper-plastic composite, glass, and metal packages, eg: bottles, containers,
Working principle
W301 Water Vapor Permeation Tester was designed with the principle of weighting method to use weight reduction method to test 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.
