Water-Cooled Light Weather Fastness Tester:
Benefits, Applications, and Buying Guide
When it comes to material weatherability and light fastness evaluation, one key piece of testing equipment you cannot overlook is the water cooled light fastness tester. An inappropriate tester may lead to unstable test data, low efficiency, or failure to meet standard requirements. But a reliable water-cooled light weather fastness tester supports accurate sunlight simulation, complies with multiple global standards, and helps assess material durability effectively.
What is the Water-cooled Xenon Arc Tester
Water-cooled Xenon Arc Tester through simulate illumination, exposed to the rain, mist spraying, alternating light and dark, temperature and humidity climates conditions to test material products’ color fading, aging, transmittance, peeling, hardness, softness and other performance changes.
This Xenon Weatherometer is widely applied to test rubber, plastic, coating, petrochemical products, automotive parts, textiles, and many other non-metallic materials.

Buying Guide: How to Choose the Right Water-cooled Xenon Arc Tester
When selecting a xenon Weatherometer, focus on these factors:
Confirm it supports your required norms (GB, ISO, AATCC, SAE, etc.).
-
Prioritize Sample Throughput
Choose water-cooled for high capacity; air-cooled only for low-volume basic testing.
Look for Irradiation control, light irradiance sensor monitor, digital setting, automatic compensating system, stepless irradiation regulation.
-
Check Lamp & Cooling System
Does it accurately simulate the solar spectrum? Find out whether a water-cooled xenon arc lamp system meets your requirements.
Does it allow users to programme test parameters themselves and does it have a storage function capable of saving additional user-defined test plans?
Please select a supplier that can provide calibration services, operational training, spare parts, and a responsive after-sales service.
Conclusion
A high-performance water cooled light fastness tester is essential for accurate, compliant material weatherability and light fastness testing. The ASTM G155 Testing Machine GT-3000 combines stable water-cooled xenon lamp technology, precise closed-loop control, large specimen capacity, and wide standard compatibility to support reliable testing across many industries.
