Type: Device for measurement of the porosity of fabrics

Purpose
Enable an air volume to go through a cloth in order to measure its porosity. Principle: measures the time necessary for 0,25 litre of air under 10mbar pressure 

Formula to convert porosimeter MK2 values in
Industry-standard n°1
(liter per m2 per min) (pressure of 200 mm of water)
5400 / time in second
(divide 5400 by the time displayed on the MK1)
Industry-standard n°2
(cm3 per cm2 per sec) (pressure of 200 mm of water)
9 / time in second
(divide 9 by the time displayed on the MK1)
