The YT3000 geotextile weathering tester is used for the light resistance, weather resistance and light aging test of various geosynthetic materials. By controlling the conditions of light irradiance, temperature, humidity, rain, and alternating light and dark in the test chamber, the simulated natural environment required for the experiment is provided, and the performance change of the sample after the light radiation is detected.

ISO 4892-2, GB/T 16422.2, ASTM D4355, JTG E50 T1163

By controlling quantitative indicators such as light intensity, temperature, humidity, and rain in the test chamber, the simulated natural conditions required for the test are provided to detect the light resistance, weather fastness and light aging properties of the sample. The instrument has online control of light intensity, automatic monitoring and automatic compensation of light energy; closed-loop control of temperature and humidity, and multi-point adjustment functions such as blackboard temperature loop control;
