UV Accelerated Weathering Tester: Your Guide to Its Features and Uses

The UV Accelerated Weathering Tester (model GT-C29) is a professional accelerated uv testing equipment widely used to simulate outdoor sunlight, rain, dew and other natural weathering environments. The harm includes color fading, discoloring, chalkiness, cracking, muddy, bubble, embrittlement, intensity, recession, oxidation etc.

Working Principle of UV Accelerated Weathering Tester

UV Accelerated Weathering Tester GT-C29 adopts UVA-340 fluorescent UV lamp as the core light source to accurately simulate the harmful effects of natural sunlight, rain and dew. Its operating principle combines ultraviolet radiation, rainfall, high temperature, condensation and dark environment into an automatic cycle, which runs repeatedly without manual intervention. Through such accelerated circulation tests, users can quickly obtain the weathering test results of test specimens, and judge the weathering resistance of materials efficiently.

Features of UV Weathering Tester

The outer case is processed by numerical control equipment with advanced technology, featuring smooth lines and practical design. This weather tester can automatically circulate ultraviolet, high temperature, condensation, rainfall and dark conditions, realizing fully automatic operation.

Uniform Air Circulation: Air channel in the cabinet applies single-cycle system and a import axial flow fan improves the air flow ability of light, heating ability, and also significantly improves the temperature uniformity in the test chamber.

Durable Specimen Holders: Specimen racks are made of stainless steel and aluminum alloy, sturdy and non-deformable.

Flexible Movement: The unit base is fitted with high-quality PU casters for easy relocation and fixation.

Reliable Drainage: Equipped with a U-shaped sedimentation device for smooth, blockage-free drainage.

safety protection devices: The weather tester power uses the residual current circuit-breaker for control loop, overload and short circuit alarm, over temperature alarm, water shortage protection.

Advantages of Using UV Accelerated Weathering Tester

High Accelerated Test Efficiency
Our accelerated uv testing equipment can can reproduce the months and years harm in several days or weeks. The detectable damages include color fading, discoloration, chalkiness, cracking, turbidity, bubbling, embrittlement, strength recession, oxidation and other common failure forms.

Excellent Environment Simulation
As a professional UV Weathering Tester, it truly simulates the combined effects of sunlight, rain, dew and temperature changes, and the test data is highly consistent with actual outdoor aging results, providing credible reference for material selection and improvement.

Flexible & Convenient Operation
Adjustable water pressure, automatic circulation, mobile PU wheels and humanized structure design make operation, movement and maintenance more convenient.

Applications of UV Accelerated Weathering Tester

Plastic & Rubber Industry
Used to test the weathering resistance of plastic parts, rubber products, polymer materials, etc., to judge their aging degree under outdoor environment.

Coating & Ink Industry
As a core accelerated uv testing equipment, it detects color fading, discoloration and peeling of coatings, paints, inks and other surface treatment materials.

Building Materials Industry
Suitable for weathering test of outdoor building panels, sealants, decorative materials, etc., to verify their service life in natural environment.

Automotive & Outdoor Products
Test automotive exterior parts, outdoor furniture, electronic appliances, packaging materials and other products that need long-term outdoor use.

Material R&D & Quality Inspection
Widely used in laboratory research, factory quality control, certification testing and other scenarios as a standard UV Weathering Tester and ASTM G154 UV Test Machine.

FAQ

Does the accelerated uv testing equipment GT-C29 comply with ASTM G154?
Yes, the accelerated uv testing equipment is a standard ASTM G154 UV Test Machine that meets the requirements of ASTM G154 and other mainstream UV weathering test standards.

Can I switch between UVA and UVB lamps?
Absolutely. The standard configuration is UVA-340; you can optionally upgrade to UVB-313 lamps based on your testing requirements for this accelerated uv testing equipment.
