Product Description:

 Function and usage

EKT-W 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 carries the standards of GB 1037-1988 ,GB/T 16928-1997, ASTM E96-00e1 ,ASTM D1653-03,TAPPI T464,ISO2528.

Working principle

EKT-W 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.
