  • Time in seconds
The measuring pressure of the MK1 is 100 mm of water (10 mbar or 10 hPa). Result is given in seconds (necessary time for 0.25 liter of air to go through 38,5 cm2 of fabric under a pressure of 10 mbar.

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 seconds

(divide 5400 by the time displayed on the MK2)

Industry standard n°2 (cm3 per cm2 per sec) (pressure of 200 mm of water)

9 / time in seconds

(diviser 9 by the time displayed on the MK2)
