Application:
The UV accelerated weathering test chamber reproduces the damage caused by sunlight, rain and dew. In a few days or weeks, the UV tester can reproduce the damage that occurs over months or years outdoors. To simulate outdoor weathering, the UV accelerated tester exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It simulates the effects of sunlight using special fluorescent UV lamps. It simulates dew and rain with condensing humidity and/or water spray. The UV accelerated weathering tester is the simplest, most reliable, and easiest to use weathering tester available.

Available Lamps:
UVA-340 Lamps
The UV tester’s UVA-340 lamps give the best simulation of sunlight in the critical short wavelength region from 365 nm down to the solar cut-off of 295 nm.
UVA-351 Lamps
The UV tester’s UVA-351 lamps simulate the UV portion of sunlight filtered through window glass. It is most useful for interior applications, for testing of some inks and for polymer damage that can occur in an environment near a window.
UVB-313 Lamps
The UV tester’s UVB-313 lamps maximize acceleration utilizing short-wave UV that is more severe than the UV normally found at the earth’s surface. Consequently, these lamps may produce unrealistically severe results for some materials. UVB-313 lamps are most useful for QC and R&D applications, or for testing very durable materials.
Features:
1) Easy to Operate
The UV tester’s simple, proven design makes it easy to install, easy to use, and almost maintenance-free. It operates completely automatically, 24 hours a day, 7 days a week. Features include:
Simple user interface for easy programming in two user-selectable languages: English, Chinese (can be customized)
Exposure conditions displayed continuously
Self-diagnostic warnings and service reminders
2) Temperature Control
All UV testers precisely control temperature to enhance accuracy and accelerate test results. Although temperature does not normally affect the primary photochemical reaction, it does affect the rate of any subsequent reactions. Therefore, the UV tester’s ability to control temperature is essential during UV exposure.
3) Spray
The UV tester includes a water spray system. Short periods of spray can be used to create a thermal shock. Longer periods can be used to achieve mechanical erosion. The UV tester can be set to produce: UV alone, spray alone, or condensation. Deionized water is recommended for all spray applications.
