Porosity check

Porosity of paragliding wing material is a worthy indicator of wing condition. The canopy is measured for porosity values in 5 different areas (or more if necessary) of the top surface using JDC calibrated device HELLO POROZIT N, measuring the time needed for 0,25 liter of air to flow through 38,5 cm² of canopy surface under pressure of 10 mbar. After the test you are informed with results and interpretation.
