HST Machine Uv Weathering Test Chamber with low price

Product Description

1. 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

(2) Structure & Material
a) Structure: The middle of the machine is the working chamber, the water system located at the bottom of machine, its top is the control cabinet and control panel. Open the door from front direction. The bottom of the chamber with high-quality PU activity wheel that can be fixed, users can move it according to their requirements positioning. - Single cycling system for air flue in the box, there's one inlet axis weeding machine which improves the flow amount of air, the heating ability and the whole temperature uniformity in the test machine. - Water source and consumption: Tap water or distilled water for 8liters per day. - Heating method is to heat liner water tank with fast heating speed and high temperature uniformity. b) Material: - Inner box: high grade stainless steel plate - Outer box: stainless steel plate SUS304 or stoving varnish for option.
