TF422 Water-cooled Light & Weather Fastness Tester
Description: The TF422 Water-cooled Light & Weather Fastness Tester (Weatherometer) evaluates the color fastness and aging resistance of textiles, plastics, rubber products, and other materials by simulating natural weather conditions such as daylight, rain, temperature, and humidity. It uses a water-cooled long-arc xenon lamp and rack sprays to replicate light and dark cycles, ensuring accurate environmental simulation. The xenon lamp, positioned centrally, generates simulated sunlight, while an outer light filter ensures only the required light affects the test samples. Heat from the lamp is dissipated by ultrapure water flowing between the lamp and the filter.
Features:
- Digital light intensity setting with real-time monitoring and automatic adjustment to meet various standards (optional 420 nm or 300–400 nm band monitoring)
- Blackboard Thermometer (BPT), Standard Blackboard Thermometer (BST), irradiance detector, and samples positioned equidistantly for accurate condition reflection, displayed as figures, charts, or curves on a large color screen
- Large, colorful display with multiple test monitoring modes (animation, digital, graphics) for easy and clear operation
- Independent timing for sample holders, allowing simultaneous different tests
- 4500W water-cooled long-arc xenon lamp for true daylight spectrum simulation
- Professional water circulation system to reduce operating costs
- Industrial temperature control (cooling) system for quick and smooth control
- Ultrasonic humidifier and professional dehumidification system for accurate and stable humidity
- Self-circulation and air filtration systems to reduce environmental requirements
- Cooling options: circulating water chillers or water cooling
- Quality assurance for 1000 hours of continuous operation
- Front and back spray patterns on samples to simulate rain and dew
