HHST Weathering Test Chamber Battery UV Aging Environmental Test Chamber

 

Application

The UV Accelerated weathering test chamber stimulates dew and rain with consideration for humidity and/or water spray equipped with fluorescent UV lamps which can completely simulate the UV spectra of sunlight, exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It’s most widely used weathering tester to test types of damages include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, strength loss and oxidation. The source adopts 8 pieces of UV lamps of 40W as the light source. The lamps are distributed on the two  sides of machine, 4 pieces for each side (UVA-340 and UVB-313 optional), 8 pieces in total .
