The IDM hydrostatic head tester, from IDM Instruments , is used to determine the resistance of textile fabrics to penetration by water at a constant rate of increase of pressure.
It is used on all fabrics which are water repellent or coated to impart resistance to water penetration. The hydrostatic pressure supported by a fabric is a measure of the resistance to the passage of water through the fabric.
The easy-to-operate bench-top instrument is manufactured using quality stainless steel. It also features high and low analogue pressure gauges, as well as a water explosion container cover and overflow tray for added operator safety.
Manufactured to internationally recognised test standards, the hydrostatic head tester from IDM Instruments allows a specimen to be subjected to a uniformly increasing pressure of water on one face, under standard conditions, until penetration occurs. Results are taken when penetration to the fabric occurs at the third place.
