• Select world famous brand low energy consumption components with stable and reliable performances.

Principle

The prepared sample is clamped between the test chambers. Nitrogen with stable relative humidity flows on one side of the film, and dry nitrogen flows on the other side of the film. Due to the humidity difference, water vapor diffuses through the film to the low humidity side from the high humidity side. On the low humidity side, the water vapor is carried by the flowing dry nitrogen to the infrared moisture sensor, and different water vapor concentrations generates different light signals. By analysis and calculation, the concentration value can be obtained and water vapor transmission rate of the sample can be further determined.
