Principle of the dynamic geotextile perforation tester:ZefTextile Testing Instruments, Testing Equipment Manufacturer


The geotextile sample is clamped horizontally in the clamping ring, so that the steel cone of the specified quality stands out Drill the sample from a height of 500mm to form a hole in the sample, and then insert a small-angle graduated cone into the hole to measure the degree of penetration.
