A Porosity Tester is a specialized instrument used to measure the air permeability or porosity of paper,
textiles, filters, and other porous materials. Porosity testing is crucial in various industries, such as packaging,
printing, textiles, and filtration, where the material’s ability to allow air or fluids to pass through is an
important quality attribute. The tester provides quantitative data on how easily air passes through a material,
which can indicate the material’s strength, density, and suitability for specific applications.
