Using the Infrared sensor method principle.

Nitrogen flow with stable relative humidity on one side of the material while dry nitrogen flow with a fixed flow rate on the other side; Because of the humidity difference, the 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. The sensor calculates the water vapor concentration and the water vapor transmission rate by analyzing the electrical signals generated by the water vapor.
