TF420 Light Fastness Tester
Description: The TF420 Light & Weather Fastness Tester evaluates color fastness to light, weather, and light aging for textiles and other materials by simulating light, dark cycles, and natural weather conditions. It uses specimen holders, rack sprays, and a long-arc xenon lamp.
Features:
- Digital light intensity setting with real-time monitoring and closed-loop control (standard 420 nm; optional 340 nm, 300–400 nm, 300–800 nm)
- 10.4-inch color touch panel with multiple test monitoring modes (animation, digital, graphic)
- Imported key components (e.g., temperature/humidity sensors, ultrasonic humidifier) from the USA, Japan, and Germany
- Blackboard Thermometer (BPT), Standard Blackboard Thermometer (BST), and irradiance detector positioned with samples for accurate data display (figures, charts, curves)
- Light energy conversion technology for wireless transmission, no additional power supply needed
- Independent timing for sample holders to conduct different tests simultaneously
- 2500W long-arc xenon lamp simulates daylight spectrum
- Industrial temperature control (cooling) system for quick and smooth control
