摘要： Gas permeability measurement apparatus is an apparatus for measuring all kinds of continuous-porous materials, including wood, paper, wood-composites, wood plastic composites (WPC), minerals, polymer-based materials, minerals, ceramics, textiles and fabrics. The apparatus is equipped with an electronic time measurement device with milli-second precision; this feature allows the permeability values to have improved accuracy and precision needed for scientific purposes. This apparatus uses falling liquid method wherein the liquid column can be easily changed according to test design. The apparatus is equipped with at least two sensors in the electronic time measurement device which are designed so that the distance between them can be easily set to 10, 15, and 20 cm. The sensors are mounted on a stand that can be moved along the liquid and gas traveling zone thereby enabling the length of liquid column to be fixed from 30 cm up to 2 meters. The main skeleton of the whole apparatus is designed so that the diameter of its glass tube may easily be changed from 0.5 to 5 cm in accordance to different standard stipulations, as well as the amount of liquid displacement required.
