This product uses fluorescent UV lamps that can best simulate the UV section spectrum of sunlight, and combines temperature control, humidity and other devices to simulate the material caused by discoloration, brightness, strength loss; cracking, peeling, chalking, oxidation and other damages caused by sunlight (UV section) high temperature, high humidity, condensation, the dark cycle, and other factors, and at the same time, through the synergistic effect of UV light and humidity to make the material a single light-resistant or a single humidity-resistant ability to reduce or fail, so that it is widely used in the evaluation of the material's weather resistance. or failure, and thus widely used in the evaluation of the weather resistance of materials, the equipment has to provide the best sunlight UV simulation, the use of low maintenance costs, easy to use, the equipment adopts the programmable controller to automatically run the
test cycle, high degree of automation, good light stability, test results reproducibility and other characteristics.
