Key Features

This instrument is used to measure the porosity (air resistance) of paper through which air of constant pressure and constant volume can pass in 10_9,999 seconds over a specified surface area. This porosity of paper bears relation with its density, formation, absorption (water, oil), appropriateness for printing etc. of paper. However, it is not suitable for measuring the porosity of rough paper like corrugated cardboard, etc. due to the problem of leakage of air from the surface of the clamped specimen.
