This UV test chamber is used in tests that incorporate UV light, temperature, condensing humidity, water sprays, and irradiance control. UV weathering resistance test chamber uses UVA-340, UVB-313 fluorescent UV lamps for a variety of test conditions. Accelerated weathering tests included color change, gloss loss, chalking, cracking, crazing, hazing, blistering, strength loss and oxidation, and many others. UV series weathering chambers are upgraded to a programmable controller and Ethernet access that provides simple operation and control.
