This document introduces a new digital filtration media pore determination test rig. The test rig can measure important characteristics of filtration media like air resistance, air permeability, maximum pore size, mean pore size, and micron rating. It provides direct digital readings on these measurements on a screen without requiring calculations. The test rig is designed to be easy to use and operate, and follows standards like BS 6410 and AARR test methods. It is a versatile instrument that can help the filter industry evaluate filtration media.
