I. Usage:
UV accelerated weathering test chamber simulates damaging effects of long term outdoor exposure of materials and coatings by exposing test samples to varying conditions of the most aggressive components of weathering - ultraviolet radiation, humidity and heat. A UV weathering test chamber uses fluorescent lamps to provide a radiation spectrum centered in the ultraviolet wavelengths. Moisture is provided by forced condensation, and temperature is controlled by heaters.
II. Features
Using CNC equipment manufacturing, advanced technology, and beautiful appearance;
Made of stainless steel, 1.2mm thickness;
Air path inside the single cycle system, import a axial fan, the air flow increases the light, heat capacity, significantly improves the uniformity of temperature in the test chamber;
Lamp: special UV ultraviolet lamp, 8 pieces of UVA lamp installed on both sides; lamp life: above1600h;
The consumption of water: tap water or distilled water to about 8 liters / day;
Heating tank for the interior heating, warming fast, uniform temperature distribution;
Automatic water tank level to prevent damage to the heating pipe air burning
Sample holder made of stainless steel or aluminum alloy;
High quality PU wheels fixed;
Drainage system using a U-shaped plot sinks drainage;
Test sample surface with UV light parallel to the plane;
Internal automatic sprinkler system installed sprinklers, adjustable water pressure;
