Rain Tester

About Rain Tester

This instrument simulates rain sprayed horizontally onto a fabric sample vertically fixed in a stainless steel tank. A standard absorbent paper is placed against the back of the sample (weighed before and after testing). Water in the jet is sprayed through a standard nozzle to form rain, and the water jet volume can be adjusted from 600 mm (24 inches) to 2400 mm (96 inches) in 300 mm (12-inch) increments.

The Rain Tester features an interactive LCD color touchscreen with preset ISO and AATCC test standards, water temperature, water jet height, and test time. A built-in water tank recovers water sprayed onto the sample and includes a heater to control the water temperature. A precision water pump automatically maintains the water jet at the set height.

It cannot be modified and can be ordered with a new rain tester. We can provide a temperature-controlled water supply system, including an electronic temperature controller, mixing tank, and solenoid control valve.

Applications

The rainproof tester can test the water repellency of fabrics or composite materials under different rainwater pressures.
