The test specimen is mounted in the diffusion cell, which is divided into a dry chamber and a controlled humidity chamber. A flow of dry nitrogen sweeps the dry side of the specimen, while the dry nitrogen carries the water vapor permeating through the specimen from the controlled humidity chamber to an infrared sensor. This sensor generates proportional electrical signals based on the water vapor concentration. The water vapor transmission rate is determined by analyzing and calculating these electrical signals. For package samples, dry nitrogen flows inside the package, while humidified nitrogen flows outside.
