About This Product
Colour fastness to light is an important property for leather, textiles and other materials, because it shows whether a colour will fade in use. In this test the specimens are exposed to artificial light at a controlled humidity and temperature, together with blue references that show the degree of exposure reached. The change in colour is then rated against a grey scale. The rotating drum keeps the exposure of the specimens even. Alongside supply within India, the Light Fastness Tester is offered for export to Kazakhstan, Bahrain, South Sudan, Estonia and Djibouti.
