Ultraviolet Weathering Test Equipment UV Accelerated Aging Chamberfor Industrial Product Validation

UV aging test chamber stimulates dew and rain with condensation for humidity and / or water spray equipped with a fluorescent UV lamp 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 to test types of damages outside that need several months or several years re-appear, damages include colour change, gloss loss, chalking, cracking, crazing, hazing, blistering, strength loss and oxidation, the machine only need several days or several weeks. 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, UVB-313 or UVA-351 optional). It makes the material damages under the sun (UV), rain (spray) reapear fastly and truly.

Application: paints, coating & inks, plastic, printing package, aluminium material, adhesive, auto & motorcycle, cosmetic, metal,electronic, electroplate, pharmaceuticals and so on.

Function:

The UV Accelerated weathering Test Chamber simulates effects from outside humidity;

Test exact temperature by black panel temp. sensor, it can repeat the tested result;

Cycling test for humidity, condensation, and spray available;

Calibrator resource and auto calibrated program for the radiancy;

Test samples: 24pcs for each at 75mm*300mm, 48pcs for each at 75mm*150mm (for Tower-type only).
