Permeability Cups

The permeability of a coating to water vapor is measured by suspending a free film of the material across the top of a wide shallow cup. Then, in a controlled environment, a desiccant is used to draw water vapor through the film into or out of the cup. Weight loss or gain of the cup’s content over a specified period is used to determine the rate of vapor transmission through the film. The permeability of a film to many other substrates in the gaseous state can be tested in a similar fashion.




GasLogger is an innovative instrument based on wireless technology that allows you to monitor and log, in real-time, both the oxygen concentration, pressure, temperature and relative humidity inside a closed container.
