POROZIT N

745 € + shipping

We have been producing and developing our flagship product since 2008. Nowdays this is the most accurate and beloved porosity meter in the paraglider industry. We have sold this product for paragliding shcools, clubs, repair shops and paraglider producers around the world in more than 40 countries. The measuring method and the specification (volume of air, diameter of cap etc.) of the Porozit N is the same as the JDC MK1, but the results are more accurate.

neodymium magnet

We have replaced the ferrite magnets with neodymium magnets. With these magnets we have increased the cohesive force by multitudes even for the normal strength model.

High rubber wall

It allows to get higher accuracy for measuring high-porosity materials. This rubber cover is more durable and resistant to wear and abrasion, and fits more accurately.

New demands

When we have started to produce porosimeters our primary goal was to facilitate the safe flight, to separate the flyable and not flyable paragliders in terms of porosity. Our device could reliably determine the threshold which is 20 seconds (defined by the JDC and paraglider producers). We have already achieved this goal with our first Porozit at 2008. Nowadays there’s a demand of paraglider owners to more accurately know the porosity of paragliders with porosity thresholds of more than 200 seconds. At this measuring limit we need to pay more attention to the amount of false air leaking in between the measurement device and the material of the glider.

FALSE AIR NEVER ENTER

When magnified, a paraglider’s material shows not a smooth, but a striated surface. The level of striation depends on the material structure, the weaving technique and the thickness of the applied barrier layer. The amount of false air of a low-porosity material is negligible. For high-porosity materials however, it’s amount can reach a more significant level, which can even surpass the amount of influx air during a measurement of the material, since the material itself has a good quality and low air throughput.

Our solution

We’ve met the challenge: our new Porozit N has a new high-walled rubber cover, which by itself already allows to get higher accuracy for measuring high-porosity materials. This rubber cover is more durable and resistant to wear and abrasion, and fits more accurately. Additionally, we have replaced the ferrite magnets with neodymium magnets. With these magnets we have increased the cohesive force by multitudes even for the normal strength model. There are two model options: the medium strength model uses 7 pieces of neodymium magnets and the extra strength model uses 8 pieces of neodymium magnets.These magnets have greater endurance, and they have an extended lifetime of their magnetic properties.

HOW TO VIDEO

In this video you can check how you need to use your Porozit. To measure porosity is a pretty easy process. You can find our how to use videos on Youtube. Currently we don’t have that much, but we are going to make more. Our plan is to make clear everything about the inspection of paragliders, some kind of trick & tips.
