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.
