This product uses fluorescent UV lamps, combined with temperature and humidity device to simulate the material decline in color, brightness, strength and cracking, spalling, powder, oxidation damage via the high temperature sun light (UV), high humidity, condensation, dark cycle etc. At the same time, through the synergy between UV and moisture resistance ability of single or single material makes wet ability weakening or failure, which is widely used to evaluate the performance of weather resistant materials, equipment is to provide the best sunshine UV simulation.

Usage and maintenance are of low cost, easy to use. Equipment uses program controller can automatic control the test cycle, with high automatic high degree. In addition, it has stable light performance and high rate of repetition test results.


The UV aging test chamber is suitable for all kinds of geo-synthetics, such as light resistance, weather resistance and light ageing
The exposure test of the sample was carried out in a fluorescent UV lamp vessel in a controlled environment. It can simulate and strengthen the environmental factors in the natural climate that are affected by light, heat, humidity, and rainfall as the main aging. It can simulate the accelerated test under long term exposure to obtain the results of the weather resistance of the material.
