UV Weathering Test Chamber
Features

• UV weathering tester machine simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering such as sunlight, rain, humidity and dew conditions, including damage caused by bleaching, color, brightness down, powder etc.
• Applicable Standards:- ASTM ,ISO ,EN ,BS ,JIS ,SAE
• Standard test specimen holder accommodates 2 panels 75×150mm
• Uses fluorescent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths.
• Moisture is provided by forced condensation, and temperature is controlled by heaters.
• Inner box is made of stainless steel, and the exterior is spray coating.
• Equipped with 8 UVA or UVB lamps.
• Programmable time controller.
