Vapometer Permeability Cups
Measures water vapour transmission rate through sheet materials
A simple gravimetric test for determining the water vapor permeability of sheet materials, such as specialty paper grades, polyethylene, building material, leather, weatherproof clothing, vinyl, foil, laminates and other thin sheet materials.
Complies with ASTM E96-80, TAPPI T-448, TAPPI T464 os-79.
The EZ-Cup Vapometer is a light weight aluminum cup with an aluminum threaded flanged ring + two neoprene gaskets and a Teflon seal, that hold the specimen in place. This design eliminates edge leakage and provides fast, secure sealing of the specimen between the gaskets.
Diameter 2.5 in (63.5 mm). Suitable for samples up to 3mm thick and can be used at any temperature, or relative humidity, to ensure product performance across different conditions. A selection of cup depths is available.
Standard Water Vapour Method
Depending on the end use, water, or a desiccant, is placed in the base of the container. The specimen is then quickly sealed, with the threaded flanged ring between the two neoprene gaskets, and placed in a test chamber that controls the atmosphere. Vapor loss, or gain, is measured by recording the weight of the sample at successive time intervals. The cups are serially numbered for an easy way to keep track of the different samples.
Accurate circular samples 2.9375″ diameter (74.61 mm) for the Vapometer can be quickly prepared using a Circular Steel Die with the 240-7B Alfa Cutter.
