Main feature
1.simulated sunlight
The damage of material durability is mainly caused by the sun's ultraviolet ray. We use UV lamps to simulate sunlight in the ultraviolet part of the short-wave, it produces very little visible or infrared spectral energy. We can choose according to different testing requirements of different wavelengths of UV ultraviolet light, because each lamp in the total energy and wavelength of UV radiation are not the same. Usually, UV lamp can be divided into two kinds of UVA and UVB.

2.UV lamp type

UVA-340 lamps: can simulate short-wave UV light in the sunlight excellently, ie sunlight from 365 nm to 295 nm cutoff wavelength.
UVB-313 lamps:UVB-313 lamps are usually issued by short-wave UV radiation than the Earth's surface in the strong solar ultraviolet radiation, which can speed up the greatest degree of material aging.However, the lamp may have caused some of the material does not meet the actual damage.UVB-313 lamp is mainly used for quality control and research and development, or on the weatherability of materials strong run the test.
UVA-351 lamp:Simulation of UV sunlight through windows, it is the aging of indoor materials for testing the most effective.

3.moisture condensation environmentIn many outdoor environment, the material wet day time can be up to 12 hours.The results show that this result is the main factor of outdoor wet dew, not rain.UV condensation through a unique function to simulate the outdoor wet erosion.Condensation during the test cycle, the test chamber at the bottom of the reservoir, water is heated to generate superheated steam to fill the entire test chamber, hot steam to the test chamber maintained at 100% relative humidity, and maintain a relatively high temperature.Sample is fixed in the test room wall, so the test sample surface exposed to ambient air in the test room.The outward face of the sample exposed to the natural environment has a cooling effect, leading to internal and external surface of the sample with temperature, the temperature difference causes the appearance of the sample in the whole process of condensation cycle, the test surface always have condensation of liquid water generated.Because exposure to humid outdoor exposure time up to ten hours a day, so a typical condensation cycle usually lasts several hours.UV offers two moist simulations.The most widely used is the condensation method, which is to simulate the best way of outdoor wet erosion.All models can be run UV condensation cycle.Conditions because some applications require the use of water spray in order to achieve practical results, some condensation cycle UV models can be run either run the water spray cycle.
 

4.the temperature control in each cycle, the temperature can be controlled at a set value.At the same time the board can monitor the temperature of the thermometer.Higher temperature can accelerate the aging process, while temperature control for reproducibility of the test is also very important
 

5. the water spray system for some applications, the water spray can better simulate the end use of the environmental conditions.Water spray in a simulated drastic changes in temperature and rainfall caused by the thermal shock or mechanical erosion is very effective.Conditions in some practical applications, such as sunlight, heat together the stroke of showers dissipated rapidly, the material will be dramatic changes in temperature, thermal shock, thermal shock for many materials, this is a part oftest.UV water spray to simulate thermal shock and / or stress corrosion.Sprinkler system with 12 nozzles, each side in the test room of 6; sprinkler system can run a few minutes and then shut down.This short cooling water samples quickly and create a thermal shock conditions.

6. irradiation intensity control: optional matching light intensity control option available to accurately type and reproducible results; light intensity control system allows users to set different requirements of different test light intensity.Feedback loop devices through its precise control of light intensity; but also can extend the life of fluorescent lamps
