Bundesmann Water Repellency Tester determines the water resistance of fabrics to the simulated rain under the moving condition. Fabric is held on the test cup under which there is rain wipers which is rotating and rub the fabric underside. The amount of the water penetrates the fabric into the test cup can be measured. And the amount of water absorbed by the fabric can be weighed and determined.RF4468 consists of 4 specimen holders of 100mm diameter cups. Rain is produced by spraying nozzles and falls down from 1500mm height from the fabrics.
Optional centrifuge is available for removing excess surface water from the tested fabrics.
