Light Fastness Testing Machine 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.

Gester Instruments Co.,Ltd has professional experience on the production of Light Fastness Tester. The following are the characteristics of colorfastness to light test machine

Fabric color fastness to light machine Feature:

1. The 2500W long arc xenon lamp is used to simulate the solar spectrum.

2. 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.Test 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 synchronously by using technolody of radio frequency.

6. With industrial temperature control (refrigeration) system for smoothly and fast adjusting temperature in test chamber.

7. 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. Xenon arc light fastness tester: 12 working positions monitoring, can set and inquire the irradiation energy.

13.Possess fault prompt functions and self-diagnostic function.

Color fastness to light test method

1. Turn on the power supply: turn the power switch on the right side of the device from 0 to 1.

2. lnstall black panel thermometer.

3. Prepare the sample. 

4. Please choose the sample according to your needs or the standard require. For exsample blue wool standard sample, cut off the white part and put it into the sample holder, then putit into the test chamber.

5. Close the door and enter the Set interface.

6. Please choose the standard you needed, like IS0 105 B02, all the parameter are fixed and do not change it.

7. Before testing, please reset the run thie. After that, click "Start0", run for 30 seconds before clicking "Xenon'.

8. When the machine reaches the set test time, it will automatically stop and the light will automatically go out.

9. Open the door, take out the blue wool cloth and compare it with the grey scalesat level 5 to check whether the color of the blue wool cloth is consistent with thatof the grey scales. For example, when the blue wool cloth and grey scales are the same color,please take out the sample and place it under the observation lamp to comparethe color difference before and after the test. lf the color is inconsistent, put the blue wool cloth back in the chamberand click Start to continue running the tests.
