POROTEST SKF
AIR FLOW METER FOR PARAGLIDER INSPECTION - Porosimeter
In order to test the state of a canopy PoroTest SKF measures the time necessary for 250 cm3 to pass through 38,5 cm2 of canopy under a 10 mbar pressure. This determination method has asserted itself as the standard accepted by paraglider manufacturers. The state of the tested fabric can be evaluated according to the tabel:
> 200 sec |
Excellent |
70 – 200 sec |
Good |
25-70 sec |
Medium |
18-25 sec |
Weak |
<18 |

Important!
With PoroTest SKF you can check the very narrow cell paragliders (CCC).
Touching the Reset button by accident does not stop the timer if the weight is not set on the Sensor panel.
Before any measurement, make certain that the rubbers that tighten the canopy are perfectly clean. They can be cleaned with a cloth soaked in water.
After fitting the canopy between the two panels, it has to be perfectly flat and even. The rubbers’ form facilitates the stretching and the smoothing of the canopy if they are positioned correctly.
PoroTest SKF is designed and manufactured by Sky Free Team Romania. We love to say: “PoroTest is made by paragliders pilots for paraglider pilots.”
Through the mini USB port, PoroTest SKF can be powered from a power bank or any charger (USB) for mobile phones. A 9V battery can also be used that is NOT included in the package delivered. A 9V accumulator may be used instead of the common battery. A high quality battery ensures a considerably longer working time.
It is not allowed to send the batteries in the packages that are transported by plane. Please purchase any 9 V battery (or rechargeable battery). The picture is for suggestion, it doesn’t matter the battery manufacturer.
