Water Vapor Transmission Rate– Electrolytic Method
Function and usage
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.
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.
0.001~100 g/ m2·24h (film & sheet, with mask can be 0.1~1000 g/
0.001 g/ m2·24h( Film & sheets ), 0.00001 g/pkg·d ( package bag &
10°C~50°C optional )
Dryness=0%RH, Humidity=30~90%RH, 100%RH
Φ80mm ,transmission area 50.24cm2
