What Is The Light Fastness Testing?
Light fastness testing is a specific type of Colour Fastness Testing, where its purpose is to subject your test samples to intense artificial light to assess the impact on the material.

GESTER Instruments co.,ltd is a dedicated manufacturer and wholesaler of physical testing instrument in China. Our products are highly appreciated by a number of world-class third-party inspection agencies, such as SGS, BV, Intertek, etc. We can know about the GESTER light fastness testing equipment.


This light fastness tester apply to light color fastness, anti-climate color fastness, light & perspiration color fastness and light aging tests of textile, paint, dye, coating, rubber, plastic, wood floor, paper and other materials, it have anti-climate functions of exposing to the rain, revolution and mist spraying.


1. The 2500W long arc xenon lamp is used to simulate the solar spectrum.
2. Xenon Light Fastness Tester: High transmittance of filter combinations and use 95% of the transmittance filters and filter cartridges. With Low power consumption but achieve the same irradiation light requirements. To make the machine is more energy saving and environment friendly.
3. Standard equipped with 420nm wave band, irradiance digital setting, real time monitoring,  closed loop automatic regulation, providing the most stable irradiance test light source for different standards (340nm, 420nm, 300-400nm and 300-800nm band optional ).
4. light fastness testing machine and radio transmission are powered by using light conversion technology, no additional power supply is required.
5. The sample is tested with black plate thermometer (BPT), black plate standard thermometer (BST), irradiance detector at the same position (in equidistance) to really indicate measuring state of the sample, the tested data is transmitted 
6 synchronously by using technolody of radio frequency.
7. Light Fastness Testing Machine With industrial temperature control (refrigeration) system for smoothly and fast adjusting temperature in test chamber With several modes of operation (spray, alternating light and dark, revolution), can simulate the real climate state.
8. Individual timing of each sample clamp may enable different sample test in a same tester and facilitate test monitor and reduce operation cost.
9. 7-inch color touch screen, various test monitor models(animation, figure and chart), simply operate, directly and clear.
10. 1000 hours of continuous operations.
11. Industrial grade microcontroller with strong antijamming capability.
12. 12 working positions monitoring, can set and inquire the irradiation energy.

13. The machine possess fault prompt functions and self-diagnostic function.
