About Product
UV Accelerated Weathering Aging Test Chamber can be simulated by the harm the sun, rain and dew on materials caused, QUV use fluorescent ultraviolet (UV) lamps simulate the effect of sunlight, the proposed use of cold rain and dew moisture, was placed on the test material under a certain temperature alternating light and moisture cycle program for testing, QUV with a few days or weeks of testing, we can reproduce the hazards outdoors for several months to several years appeared. Hazard types include: fading, discoloration, loss of light, powder, crack, turbidity, bubble-based, embrittlement, strength decline and oxidation.
Usage
UV Accelerated Weathering Aging Test Chamber is mainly used in paint and ink paint, resins, plastics, printing and packaging, aluminum, adhesives, car and motorcycle industry, cosmetics, metals, electronics, electroplating, medicine and other fields. Conform ASTMG53-77 specification GB ﹑ GJB MIL CNS ﹑  ASTM JIS IEC ﹑ Fed Test AATCC DIN ﹑ SAE standard

Structure
1. The housing interior are made of high quality stainless steel, the sample holder for the aluminum base frame with box spring composed linings and done;
2. The main controller intelligent digital control device, user-friendly design methods of operation, easy to use;
3. Enter the digital calibration system, built-in common thermocouple measurement accuracy and stability;
4. position adjustment and AI regulatory function, multiple alarm mode;
5. Despite the ultraviolet (UV) only 5% of the sun, but it is causing a major decline in outdoor durability of light factor because photochemical reaction of sunlight with decreasing wavelength of the impact increases, and therefore the material physics simulation sunlight when the impact of destructive nature, do not need to reproduce the entire spectrum of sunlight, in some cases, only the analog shortwave UV light can be;
6. The use of UV lamps because they are more stable than other lamps, and better able to reproduce the test results;
7. Using Fluorescent UV lamps simulate light effects on the physical properties, such as brightness down, fading, peeling, etc., is the best way, the most number of UV fluorescent tubes produced by ultraviolet light, visible light and infrared light instead of UVA -340 simulated solar ultraviolet choice;
8. UVA-340 can be an excellent simulation of the critical short-wavelength range of the sunlight spectrum, i.e. a wavelength range of 295 to 360nm spectrum, UVA-340 produced only in the UV wavelength spectrum of sunlight can be found;
9. UVB-313 for maximum acceleration test, UVB-313 can provide results quickly, short wavelength UV they employed more intense than on Earth surface is usually found in UV light. Although many of these UV wavelengths shorter than the natural light to maximize the accelerated test;
10  exposure mode: steam condensation mechanism;
11. The surface of the sample after a predetermined exposure time into non-irradiated state simulation at night, when the surface of the sample still being exposed to the heating effect of a mixture of saturated indoor hot air and water vapor, and continue to be around the back of the sample space air cooling, condensation forming surface of the sample exposed state.
12. The ultraviolet radiation sensor (optional);
13. UV aging chamber with ultraviolet radiation sensor, a high-precision photometric control system that can allow the user to select a desired light intensity, light intensity can be continuously monitored and automatic precise maintenance.
