Light & Weather Fastness Tester TF420

4.57 (7 reviews)

Weatherometer,  Xenon Test Chamber, to determine color fastness to light, weather and light aging of various colored textiles, Light and weather fastness tester. Light & Weather Fastness Tester complies with ISO105-B02/B04, AATCC 16-2003, GB/T 8427/8430, etc.



This Weatherometer is equipped with calibrated lamps, specific filters, very accurately monitored irradiance, purified water, controlled atmosphere (humidity and temperature) and predefined light, dark and rain cycles durations to simulate a lighting exposure environment(both light and dark cycles), to determine color fastness to light, weather and light aging of various colored textiles and other materials, as for these applications, you can call this weather ometer a light fastness tester or fadeometer. In addition, It can shorten the testing time via using xenon arc irradiation in a chamber, that’s why it’s also called xenon arc weathermometer chamber.


  • 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)
  • 10.4 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
