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 machine 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.
1. The case is crafted using numerical control equipment, featuring smooth lines and a beautiful design.
2. The cabinet is made from 1.2mm thick SUS304# advanced stainless steel.
3. The cabinet's air channel uses a single-cycle system with an imported axial flow fan to improve air flow, heating efficiency, and temperature uniformity within the test chamber.
4. Equipped with eight dedicated UV lamps (UVA-340 or UVB-313 optional), four on each side, totaling two sides, each lamp rated at 40W.
5. The lamps have a lifespan of over 1600 hours.
6. Consumes approximately 8 liters of tap or distilled water per day.
Temperature Measurement:
7. The test chamber temperature is measured by a sensor on a blackboard (dimensions: 75mm width, 100mm height, 1.5mm thickness) placed at the center of the exposure test area. The temperature gauge has a range of 30~80℃ with a tolerance of ±1℃. Illumination and condensation are conducted separately, with condensation controlled by heating the water.
8. Made of stainless steel and aluminum alloy.
9. The unit's base is equipped with high-quality PU wheels for easy movement.
10. Utilizes a U-type deposition device for efficient water drainage.
UV Light Parallelism:
11. The test sample surface is parallel to the UV light plane.
12. Features an automatic sprinkler system with adjustable water pressure.
13. Power control includes a residual current circuit-breaker, overload and short circuit alarms, over-temperature alarms, and water shortage protection.
14. This advanced weathering tester ensures comprehensive and accelerated testing to predict the durability and longevity of materials under various environmental conditions.
