The yellowing resistance Test Chamber is suitable for simulating the ultraviolet radiation and heat of sunlight, the sample is irradiated by ultraviolet rays and temperature in the machine, after a period of time, the degree of yellowing resistance of the sample is observed, and the stained gray mark can be used as a reference to determine the level of yellowing, and the test time is determined according to the manufacturer's agreement. The machine has complete accessories, which can be used as a basic yellowing resistance test, or as an aging testing machine and oven, showing the function of one machine for multiple purposes.
It is used for the accelerated yellowing test of materials (generally at 70 °C, the material is tested in this chamber for 3 hours, which is equivalent to 2 months of yellowing results in the natural environment). The yellowing grade of the material can be determined by the gray label of pollution. It is also possible to visually measure the degree of yellowing of the material
