At the core of the Water Vapor Absorption Tester is a straightforward design featuring six stainless steel cups inserted into a plastic base. This arrangement ensures their vertical positioning, creating an optimal testing environment for assessing water vapor absorption capabilities.

The Leather Water Vapor Absorption Tester 's effectiveness lies in its simplicity. To conduct a test, 50ml of water is added to the testing container. Subsequently, both the sample and impervious materials are installed on the container's mouth. The testing process occurs in a specified environmental condition, allowing the mass change before and after testing to determine water vapor absorption accurately.

• Weighing the Sample: The initial step involves weighing the sample and recording its weight, establishing the baseline for evaluation.

• Container Preparation: A container is selected, and its screw is loosened to facilitate subsequent steps.

• Water Addition: Exactly 50ml of water is added to the container, ensuring precision in the testing environment.

• Sample Placement: The sample is placed on the container's mouth without direct contact with water.

• Film Application: A film is positioned atop the sample, by covering the container lid and tightening the compression screw.

• Testing Duration: The specified testing time elapses, during which the EN 344 Water Vapor Absorption Tester  evaluates the water vapor absorption capabilities of the material.

• Weighing After Testing: Post-testing, the sample is extracted, and its weight is measured again.
