DRK-UV-300 UV aging test chamber

DRK-UV-300 UV aging test chamber adopts imported UVA-340 fluorescent UV lamp as light source, which can simulate the damage caused by sunlight, rain and dew.

The UV weatherproof box uses fluorescent ultraviolet lamps to simulate the effect of sunlight, and uses condensed moisture to simulate dew. The material to be tested is placed in a cycle program of alternating light and moisture at a certain temperature for testing, and an accelerated weather resistance test is performed on the material to obtain the results of the material’s weather resistance. UV boxes can reproduce hazards that occur outdoors for months or years in days or weeks. Hazard types include: fading, discoloration, loss of gloss, pinking, cracking, turbidity, bubbles, embrittlement, strength, decay, and oxidation. This machine includes a spray device.

This ultraviolet accelerated aging test box can simulate the environmental conditions of ultraviolet, rain, high temperature, high humidity, condensation, darkness and other environmental conditions in the natural climate. By reproducing these conditions, it is combined into a cycle, and it is automatically executed to complete the number of cycles. This is how the UV aging test chamber works. During this process, the equipment can automatically monitor the temperature of the blackboard and the water tank; by configuring the irradiance measurement and control device (optional), the light irradiance can be measured and controlled to stabilize the irradiance at 0.76W/m2 /340nm or the specified setting value, and greatly extend the life of the lamp.
