UV Light Accelerated Weathering Tester

Name: UV Light Accelerated Weathering Tester
Brand: Xi'an LIB Environmental Simulation Industry

UV light accelerated weathering tester simulates the damaging effects of sunlight, dew, and rain on materials in a controlled laboratory environment. By using fluorescent UV lamps (UVA-340 or UVB-313), the tester replicates the ultraviolet portion of sunlight, which is primarily responsible for the photodegradation of polymers and coatings.

It is mainly used to evaluate the weather resistance performance of the following materials: plastics, rubber, coatings, paints，automobile exterior components ，building materials ，printed materials, etc.

Model: UV-SI-260

Standard: ASTM G154,G151, G154,ISO 4892,D4329, D4587, D4799, ISO 4892-3，SAE J2020,EN 1297，IEC 60068-2-5

UV Light Accelerated Weathering Tester

UV Light Accelerated Weathering Tester Features and Benefits

1. 3 Test Phases Can Be Carried Out

The ultraviolet irradiation phase, simulating the ultraviolet rays of the sun during the day; the condensation phase, simulating the influence of dew and water vapor at night or in the early morning; the water spraying phase, increasing the intensity of thermal shock and erosion to simulate rain showers.

2. Realistic UV Simulation
Utilizes UVA-340 or UVB-313 lamps to closely mimic the damaging UV portion of natural sunlight.

3. Fast and Reliable Results
Accelerates the natural weathering process, enabling rapid evaluation of material durability within days or weeks instead of months or years.

4. Controlled Test Environment
Allows precise control of irradiance, temperature, and humidity, ensuring consistent and reproducible testing conditions.

Details of UV Light Accelerated Weathering Tester

Fluorescent UV Lamps	8 high-performance UV lamps (UVA-340 or UVB-313), arranged in parallel to provide uniform irradiance across all sample positions. Each lamp has a lifespan of up to 1600 hours and is easy to replace.
Water Circulation & Condensation System	Automatic water supply and drainage system to support condensation cycles. The system maintains stable humidity levels by creating a saturated vapor environment during the dark phase, simulating night-time dew.
Black Panel Thermometer & Radiometer	Built-in black panel thermometer (BPT) and optional UV radiometer ensure accurate monitoring and control of surface temperature and UV intensity.
Sample Holder	Corrosion-resistant aluminum sample holders, capable of holding up to 56 standard test panels (typically 75 × 150 mm). Custom sample fixtures are also available for 3D objects.
Remote Monitoring and Control	The tester supports remote access via Ethernet or USB interface, allowing users to monitor test progress, adjust parameters, and download data logs from a PC or mobile device.
