LFY-302 light fastness tester

LFY-302 light fastness tester

The main purpose
It is used to quickly determine the sunlight resistance of dyes, textiles and other materials.
Instrument characteristics
1. The light source adopts XQl500 xenon arc lamp as the radiation source. The visible light range is 380nm~750nm, and the ultraviolet range is 300nm~380nm, which is very similar to sunlight. This radiation source is equivalent to the result of sunlight measurement.
2. The sample rack can be turned 180 degrees automatically while it is revolving.
3. The temperature and humidity of the laboratory can be set as required.
