Yellowness Test Chamber

Yellowness Test Chamber is suitable for the simulation of sunlight of ultraviolet radiation and heat. Sample in the test zone is affected by ultraviolet irradiation and temperature, after a period of time, observe the degree of resistance to yellowing. This machine is to simulate the atmospheric environment of the ultraviolet sunlight. The appearance change of test sample is thought to test under 50 ℃ for 9 hours, theoretically equivalent of exposure in the atmosphere for 6 months.
