LFY-302 Sunlight Fastness Tester

Main application
Used for rapid determination of the sunlight resistance of dyes, textiles and other materials.
Instrument features
1. The light source adopts the XQl500 type xenon arc lamp as the radiation source. The emitted visible light range is 380nm to 750nm, and the ultraviolet range is 300nm to 380nm. It is very similar to sunlight, and such a radiation source is equivalent to the result of sunlight measurement.
2. The sample holder rotates while automatically flipping 180 degrees.
3. The laboratory temperature and humidity can be set according to needs. Technical indicators
1. Light source: 1 xenon arc lamp, power 1500W, lifespan 1000 hours
2. Quartz glass tube: outer diameter 68mm, length 150mm, wall thickness 2mm
3. Sample holder diameter: Φ204mm
4. Sample clamp size: 135mm × 45mm
5. Exposure area: 100mm × 24mm
6. Sample rotation: 5r/min, self-rotation: rotates 180 degrees each time it completes one revolution
7. Laboratory humidity: 20%-70% (±10%), can be set as needed and automatically controlled
8. Cumulative test time: maximum 99.99 hours
9. Working time of xenon arc lamp: can be accumulated, maximum 99.99 hours
