The hydrostatic head is a method of measuring the waterproofness of a fabric. The resulting measurement is in millimeters and refers to how high a column of water standing on the fabric would have to be before the water penetrates the fabric. For the best fabrics, results can be as high as 30,000mm, or 30 meters, before it penetrates the fabric.
The hydrostatic pressure test Evaluates a material\'s resistance to water penetration. The test is performed using a machine that reproduces the downward pressure that a column of water of this height would produce. The machine increases the pressure of the water being pushed against the fabric until water is visible on the other side. The pressure required to push water through the fabric is then calculated into a gaugebeen converted for the height of the water column. This provides the result of the hydrostatic head test in millimeters.
The digital hydrostatic head tester is used to test the waterproof properties of fabrics through waterproofing works such as canvas, coated fabrics, decking fabric, tarpaulin, rainproof fabrics and geotextiles.
The internally installed water tank design and the original water pressure compensation system ensure the stable and accurate rising speed .
