A few points. First, I purchased one of these previously and used it. Second, be aware that you can use this to compare fabric performance. However, you cannot compare the results to lab tests using instruments that meet the AATCC or ISO standards. These require a testing area (the area inside the upper clamp ring) of 100 square CM. Although the literature that came with your tester claims it meets the requirements of the standards, the area inside the ring is actually less than 40 square CM. As the test area decreases, the resulting HH increases because less tension is placed on the test fabric. The error can be substantial, depending the tensile strength and production quality of the fabric. Third, the gauge is calibrated in PSI and kv/cm2. 14 PSI is just under 10000mm or 1000cm of water column. I don't know what you were referring to as you read off units in 1000s. Finally, under the standards, the test ends when three drops come through. Anyway, it is a pretty good device, especially for the money, but you cannot compare the results to manufacturer's claims.

Nice to see the actual device. 👍👍Interesting to see how those cheaper tents fare.

I had no idea they made such devices. Really cool You should make yourself a silnylon lab coat for future testing lol Thanks for the video

Does the test damage the HH of the material? Ie can i use it to test my current tent or is it for scrap material?

I think to a certain extent the fabric will be harmed. If the test was done in a certain area that wasn't critical it would be fine.

Hi! Can you tell me where you got this device. I also do testing of outdoor gear and I’d love to try doing tests of hydrostatic head. Thanks!

Really interesting! The silnylon seems to fail by stretching to the point that you get holes between the threads, while the silpoly has less of a stretch and thus survives more pressure. I guess it slightly destroys the fabric, but not so much that it can’t be fixed with an added layer of, say, silicone tent treatment . While not being certified for it, I guess you can use it for testing slightly more porous fabrics too. Just in a less scientific way. At a certain pressure, how much time do you use to force a certain amount of water through the fabric? Such as the volume of the upper ring before it spills over?
