Used for light fastness, weather fastness and light aging test of non-ferrous materials such as textile, printing and dyeing, clothing, automobile interior accessories, geotextile, leather, wood-based panel, wood floor, plastic etc. By controlling the light irradiance, temperature, humidity, rain and other items in the test chamber, the simulated natural conditions required by the experiment are provided to test the sample’s color fastness to light and weather resistance and light aging performance. With on-line control of light intensity; Light energy automatic monitoring and compensation; Temperature and humidity closed loop control; Blackboard temperature loop control and other multi-point adjustment functions. In line with American, European and national standards.
