Digital MK2 Porosity Tester

Passing a defined volume of air through a fabric to measure its porosity. The porosimeter measures the time required for 0.25 litres of air to pass through 38.5 cm2 of tissue under a pressure of 10 mbar. The result in seconds can be converted to litres per m2 per minute (l/m2/min).

This porosimeter has been developed and is manufactured in Switzerland by JDC Electronic SA following a very strong demand from paragliding manufacturers, mainly for safety reasons. This instrument has quickly become the reference to measure porosity.
