Water Vapor Transmission Rate Test System
Water vapor transmission rate test system or tester is a machine that’s used professionally to measure the rate of water vapor transmission for different materials like back-sheets, waterproof substances, medical components, plastic films, building thermal insulation items, and more. The instrument helps determine the permeability, that is, the passage of water vapour through the material. Therefore, it’s the water vapour mass that’s transmitted through a unit area during a unit time under specified temperature and humidity conditions. The testing procedure helps control the technical indicators of the materials that further helps suffice the production requirements.
