Summarize

This instrument uses the UV lamp that can simulate the UV spectrum of sunshine, and the temperature control and humidity control unit to produce various scenarios, such as discoloration, brightness, strength degradation, breakage, peel off, pulverization, oxidization and harmful sunshine (UV light), high temperature, high humidity, condensation, darkness and rain, and uses simultaneously the collaborative function between UV light and dampness to make the single light fastness capacity or the single humidity fastness capacity of material weaken or become ineffective; thereby the instrument is widely used for evaluating the weather-resisting capacity of material.
