Product Information

This water vapor permeability tester utilizes the inverted cup method and is often referred to as the Gore Test. The PermaVape has six test stations over a bath that can be heated to the required temperature of 23°C and maintained evenly throughout the bath through a circulation pump. The test station platform is easily adjustable to ensure that the samples are immersed to the proper depth in the bath. Annex C of ISO 15496 gives detailed examples of why the inverted cup method is a more accurate test than the dry desiccant cup method.
