Sun and rain chamber (Rain chamber) G-4005

The G-4005 Air-Cooled Xenon Arc Aging Tester is designed to simulate full-spectrum sunlight, temperature, humidity, and rain to evaluate the weather resistance of materials. Using a 1.8 kW air-cooled long-arc xenon lamp (Q-LAB, 3 pieces), the chamber reproduces the effects of solar radiation, ultraviolet damage, high-temperature exposure, humidity, and sudden rain conditions.

It is widely used for accelerated aging tests of plastics, coatings, paints, rubbers, textiles, automotive interiors, photovoltaic components, and outdoor construction materials.
