JDC Porosimeter MK1


  • $2,190.00

Type: Device for measurement of the porosity of fabrics
Dimensions: 150 x 230 mm
Weight: 2.4 kg

General data
This easy-to-use, reliable and very precise porosimeter was developed and manufactured by JDC ELECTRONIC SA, following a high demand from the free flight lovers, mainly for security. Very quickly this instrument became the reference in matter of porosity measurement and is now used and appreciated world wide.

Enable an air volume to go through a cloth in order to measure its porosity. Principle: measures the time necessary for 0,25 liter of air under 10mbar pressure to go through 38,5 cm2 of cloth.

Fields of application
Quick test of cloth porosity used for example in paraglider, spinnaker & balloon manufacture
Measures a cloth degradation in order to warn the paragliders of properties and security decrease of its canopy.
Evaluation of the present and resale value of second-hand paragliders
Laboratory study of cloth wear (coating adherence, etc.).

The MK1 is frequently used by
Cloth manufacturers
Free flight schools
Free flight shops
Paragliders and hanggliders manufacturers
Paper manufacturers

Technical specifications
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 MK1 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)
