Product Introduction
Application:
GT-C29 UV Accelerate Weathering Tester use UVA-340 fluoresvent UV lamp as light sources which can simulate the harm of sunshine, rain and dew. The operating principle of this machine 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. 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.
Feature
- The case is made from numerical control equipment,which is with advanced technology, smooth lines, beautifully designed.
2. Accelerated weathering tester: 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. Accelerated weathering chamber: lamp lifetime: above1600h.
6. Water source and consumption: about 8 L tap water or distilled water every day.
7. Type of heating: water channel heating with quick warming and uniformity temperature distribution.
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. - The uv testing machine power uses the residual current circuit-breaker for control loop, overload and short circuit alarm, over temperature alarm, water shortage protection.
