UV Accelerated Test Chamber
Product description:
UV Accelerated Test Chamber can simulate the hazards caused by sunlight, rain and dew.
UV Accelerated Test Chamber used in paint and coatings, automotive industry, plastic products, wood products, glue, etc.
Applications:
1. Simulate the sun, rain spray and condensation resulting damage to test the materials by exposure to sunlight with moisture and temperature.
2. To get the results of damage after several days or weeks which is equal to expose to outside for a few months. The damages include fading, discoloration, brightness down, powder, crack, blur, brittle, strength decreases and oxidation.
3. Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.

UV Chamber Structure:
The inner bladder of the chamber is made of imported high-class stainless steel plate while the outer bladder is made of SUS 304 steel plate.
The heating mode adopts inner bladder trough type heating with its rapid temperature rise and even temperature distribution.
Control System:
Adopts black aluminum plate to connect temperature sensor and adopts black board temperature meter to control heating so as to ensure more stable temperature.
The radiometer probe is fixed so as to avoid the frequent installation and disassembly.
The radiation quantity adopts the special UV irradiatometer with high-precision display and measurement.
The radiation intensity is not more than 50W/m2.
The illumination and condensation can be controlled independently or alternating and circularly.
