To determine the penetration resistance of fabrics or composites at different intensities of water impact. Simulated rain horizontally impacts fabric samples mounted vertically in a stainless steel bath. Samples are backed with a standardised blotting paper which is weighed before and after each test. The rain is formed by a column of water which can be adjusted from 600mm (24in) to 1500mm (60in) or 2400mm (96in) depending on model in 10mm (3/8in) increments, applied via a standardized nozzle. Available in versions with 1500mm (60in) or 2400mm(96in) columns. Provided with color touchscreen controller with preset AATCC and ISO test conditions, automatically controlling water pressure, temperature and test time, built in calibration functions, and automatic water level.
