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.

For the testing of textiles color fastness, you can also choose a Water-cooled Light & Weather Fastness Tester as an alternative.


  • 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.

    Dos & Don’ts when operating the xenon lamp weatherometer?

    1 Do not open the right box cover during the operation of the equipment. The right box body of the weather ometer is mainly the electrical function component. There is a high dangerous voltage above 10kV when the xenon arc lamp flip-flop works. Removing the lid of the box may cause the personnel to touch the electrical component part, resulting in electric shock.

    2. Do not try to manually press the protection switch of the test storehouse for lighting operation when the test storehouse glass door is opened. It is forbidden to open the test storehouse glass door when the xenon arc lamp is ignited.

    3. Do not direct view of the xenon arc lamp light source of the fadeometer in the unprotected state to avoid damage to the eye.

    4. Operators should keep their attention in the process of operation in order to prevent the occurrence of dangerous failures caused by negligence.

    5. The xenon arc weatherometer must be disconnected from the power supply before the maintenance of the equipment. The maintenance of the light fastness testing machine, especially for the electrical part, should be operated by special technicians.

    How to use the fade o meter? Through this article, I think you might have got some information. If you want to know more about xenon weatherometer price, please contact us.
