GT-C29 Intelligent UV Accelerate Weathering Tester use UVA-340 fluoresvent UV lamp as light sources which can simulate the harm of sunshine, rain and dew. The UV Accelerate Weathering Tester can reproduce the months and years harm in several days or weeks. The harm includes color fading, discoloring, chalkiness, cracking, muddy, bubble, embrittlement, intensity, recession, oxidation etc.
The operating principle of accelerated weathering chamber is combined the ultraviolet rays, rain, high-temperature, condensation and darkness as a circulation and repeat the circulation automatically. We can get the weathering test result of specimen by these circulations.

Feature of UV Accelerated Weathering Chamber
1. The case is made from numerical control equipment,which is with advanced technology, smooth lines, beautifully designed.
2. Material of the cabinet is thickness 1.2mm, SUS304# advanced stainless steel.
3. Air channel in the cabinet applies single-cycle system and a import axial flow fan improves the air flow ability of light, heating ability, and also significantly improves the temperature uniformity in the test chamber.
4. Lamp: the dedicated ultraviolet, UVA-340 or UVB-313(option), 8 lamps, 4 on each side with a total of 2 sides,40W/1
5. Lamp lifetime: above1600h
6. Water source and consumption: about 8 L tap water or distilled water every day.
7. The uv aging chamber was measured by sensor on blackboard( fixed width 75㎜, height 100㎜, thickness 1.5㎜), this blackboard need to be put the center area of exposure test, temperature gauge measure range is 30~80℃, tolerance is ±1℃. Illumination, condensation need to proceed separately, condensation controlled by heating the water temperature.
8. The specimen holder is made of stainless steel and aluminium alloy.
9. Bottom of unit is fixed by high quality PU running wheel.
10. Drainage system drains water with U type deposition device.
11. The test sample surface is in parallel with UV light plane.
12. Installation of automatic sprinkler inside the spray system, water pressure can be adjusted
13. The power uses the residual current circuit-breaker for control loop, overload and short circuit alarm, over temperature alarm, water shortage protection.
