Application industry (not limited to the following):
- Paint ink paint, resin, plastic
- Printing and packaging, aluminum, adhesives
- Motorcycle industry, cosmetics,
- Metal, electronics, electroplating, medicine and so on.
Applications function:
- Simulate the sun, rain spray and condensation resulting damage to test the materials by exposure to sunlight with moisture and temperature.
- 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.
- Provide reference with testing data for improvement of existing materials, or to assess the impact of changes in product durability and other aspects.

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.
Test Specimen Mounting:
The standard test specimen holder accommodates 16 panels 75×150mm. The test panels are actual the side wall of the chamber. To properly seal the chamber, it is important to have every panel holder filled with specimens or blank panels and to have panel holders in place.
Test standard(inculding but not limited to... ):
Compliance with ASTM G53-77 specifications GB, GJB, MIL, ASTM, CNS, IEC, JIS, AATCC, DIN, Fed Test, BS and SAE.
