【Scope of application】

The YT3000 geotextile weathering tester is used for the light resistance, weather resistance and light aging test of various geosynthetics. 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.
