GT-C29 Intelligent UV Accelerated Weathering Tester

Accelerated Weathering Tester Application GT-C29

The GT-C29 Intelligent UV Accelerated Weathering Tester employs UVA-340 fluorescent UV lamps to replicate the harmful effects of sunlight, rain, and dew.

This UV Aging Chamber operates by combining ultraviolet rays, rain, high temperatures, condensation, and darkness in a cyclical process. By repeating these cycles, the device can simulate years of weathering in just a few days or weeks. The resulting damage includes color fading, discoloration, chalkiness, cracking, muddiness, bubbling, embrittlement, loss of intensity, and oxidation.

UV Aging Chamber Feature

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 temperature of the test 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.
