Xenon lamp aging testing machine is a comprehensive climate testing machine, in addition to climatic aging test, the light fastness of materials can be carried out to test, polymer materials exposed at simulated sunlight. It simulates the light,temperature, rainfall, condensing, humidity to test the materials; it can be used for choosing new materials, improving existing materials, or assessment of change in material composition;It is divided into air-cooled 2.5kw and water-cooled 6.5kw with water-cooled machine.
