Test Principle

The pre-conditioned specimen is clamped in the test cell, nitrogen with stable relative humidity flows on one side of the specimen while a stream of dry nitrogen flows on the other side. Due to the humidity difference, water vapor permeates through the specimen from the high humidity side into the low humidity side, and is carried to the infrared sensor by the dry nitrogen flow. By analyzing the electrical signals generated by the water vapor, the sensor calculates the water vapor concentration and the water vapor transmission rate.
