UV Accelerated Weathering Tester

Product description:

UV accelerated weathering test machine ,which as a kind of environment test chamber ,can be simulated by the harm the sun, rain and dew on materials caused, QUV use fluorescent ultraviolet (UV) lamps simulate the effect of sunlight, the proposed use of cold rain and dew moisture, was placed on the test material under a certain temperature alternating light and moisture cycle program for testing, QUV with a few days or weeks of testing, we can reproduce the hazards outdoors for several months to several years appeared.and mainly used for UV coating ink, paint, resins, plastics, printing and packaging, aluminum, cement, automobile motorcycle industry, cosmetics, metal, electronics, electroplating, medicine, etc.

Product Advantages：

Cost-Efficient Performance: Low operational and maintenance costs, paired with intuitive operation for seamless integration into any lab.

Advanced Automation: Programmable controller enables unattended test cycles with precise timing and automatic transitions between light, condensation, and dark phases.

Consistent & Repeatable Results: Stable UV output and tight temperature uniformity (±3℃) guarantee high repeatability across tests.

Versatile Simulation: Replicates harsh natural climates—UV radiation, humidity, condensation, and thermal cycling—to accelerate aging processes.

Customizable Testing: Optional UV-A340 (315–400nm) or UV-B313 (280–315nm) lamps cater to diverse material requirements.

Product Features：

Multi-Factor Aging Simulation: Combines UV exposure, high-temperature aging, and condensation cycles to evaluate color fading, strength loss, cracking, oxidation, and adhesion failure.

Intelligent Cycle Control: Programmable light/condensation cycles (e.g., 4H/4H or 8H/8H) with a 0–9999h59min timer.

Real-Time Monitoring: Digital displays track temperature, humidity, and irradiation intensity during testing.

Compact Design: Optimized chamber layout ensures uniform UV distribution and efficient space utilization.

Wide Applicability: Ideal for geosynthetics, automotive coatings, plastics, textiles, and rubber products.

Accessories ：

UV Lamps: 4pcs UV-A340 or UV-B313 (user-selectable).

Sample Holders: Adjustable racks for flat specimens (max. 12 samples).

Humidity Sensor: Precision probe for condensation monitoring.

User Manual: Multilingual guide (English/Chinese) with safety protocols.

Calibration Certificate: Traceable to NIST standards.

Our UV aging tester has the same performance as the QUV Accelerated weathering tester and is a perfect alternative to the QUV Accelerated weathering tester. We use the same power supply and lamps, the same spectral range, and the parameters and performance are exactly the same as the QUV Accelerated weathering tester.

Our UV weathering tester is also a perfect replacement for the Atlas UVTest? Fluorescent / UV Instrument and meets all the testing standards of that model.
