Máy thử khả năng chống thấm nước bề mặt
DM – 22 applies to determine the resistance of any fabrics, which may or may not have been given a water-repellent finish, to surface wetting by water. It is not intended to predict water proofness, since it does not measure the penetration of water through fabric. The main parts use stainless steel.
