Elcometer 5100 Payne Permeability Cups
The Elcometer 5100 Payne Permeability Cups are precision instruments made entirely of anodised aluminium, designed to determine the permeability or permeance of films such as paints, varnishes, plastics, cellophane, and other coating materials. They are essential for evaluating the barrier properties of materials used in packaging, coatings, and protective applications.
The testing process involves securing a film between a sealed ring and the cup, which is partially filled with water or a desiccant, depending on the test method. As water evaporates or is absorbed, a weight change is recorded over time. This weight change, in relation to the thickness of the film, is used to calculate the material’s permeability rate.
Accurate, durable, and easy to use, the Elcometer 5100 is ideal for laboratory testing and quality control procedures where consistent and reliable measurements are required.
