Under a certain test temperature, a constant humidity difference is generated between two sides of the test specimen. The water vapor permeates through the specimen into the dry side and then is taken to the sensor, where proportional electric signals will be generated. The water vapor transmission rate and other parameters can be obtained by analyzing and calculating these electrical signals.


This test instrument conforms to the following standards:
ISO 15106-3, GB/T 21529, DIN 53122-2, YBB 00092003


This instrument is applicable to the determination of water vapor transmission rate of:
