Complete Product Line for Water Vapor Transmission Rate (WVTR) Tester
By studying various test methods of water vapor transmission rate, Labthink manufactures many WVTR Tester based on ASTM E96 (gravimetric method), ASTM F1249 (infrared sensor method), and ISO15106-3 (electrolytic sensor method). Labthink has the most complete product line of water vapor transmission rate tester in packaging industry worldwide.
Water vapor transmission rate is a measure of the passage of water vapor through a membrane. It is the rate of water vapor transmission per unit area per unit of vapor pressure differential under test conditions.
It is also known as water vapor transmission rate (WVTR) or moisture vapor transmission rate (MVTR).
