TF420 Light & Weather Fastness Tester



Light & Weather Fastness Tester , to determine color fastness to light, weather and light aging of various colored textiles and other materials by simulating both light and dark cycles and nature weather conditions by specimen holders and rack sprays and long-arc-xenon lamp equipped.



  • Light intensity set digitally, real-time monitoring, closed-loop controlled and automatically adjust to meet the different standards (standard 420nm; 340nm, 300~400nm, 300~800nm is offered on request)
  • 4 inch large color touch panel, a variety of test monitoring modes (animation, digital, graphic) operate easily and clearly.
  • All key components such as temp, and humidity sensors, ultrasonic himidifier are imported from USA, Japan, Germany, etc.
  • Blackboard Thermometer (BPT), the Standard Blackboard Thermometer (BST), Irradiance detector and samples placed in the same position, a true reflection of the sample under test conditions, the data displayed as figures, charts, curves on the large color screen, no need to stop for observation.
  • Detection and wireless transmission using light energy conversion technologies for energy, not the other home power supply.
  • Sample holders can be timed independently to achieve different tests simultaneity in the same machine
  • Rated 2500W long arc xenon lamp simulate daylight spectrum.
  • Industrial temperature control (cooling) system offers quickly and smoothly control
  • Set of Sample Holders, set of Blue Wool Fabric (L1~L8), Gray Scale (Changing), Arc xenon Lamp and other
