water impact penetration tester
Rain Tester is designed for determining the water-repellent property of fabrics or composite materials under different rainfall pressure .
This instrument can simulate rain horizontally spraying to the tested sample which is vertically fixed in the stainless steel tank. The back of the specimen is adhered to the standard suction filter paper (weighing before and after the test). The water in the water column is sprayed into the rain by the standard nozzle, while the water column can be changed from 600mm(24 inches) to 2400mm(96 inches) by 300mm inciments (12 inches).
