Instrument description:
Equipped with ultraviolet UVA or UVB lamp tube, can simulate ultraviolet spectrum of sunlight, program setting temperature, light and rain conditions.It can simulate the harm caused by sunlight, rain and dew on the material. UV USES the ultraviolet lamp to simulate the effect of sunlight irradiation, and cold simulates the rain and dew of moisture.The tested material was placed in a cycle of alternating light and moisture at a given temperature.UV testing over days or weeks can reproduce the damage that can occur outdoors for months to years.Types of hazards include: fading, discoloration, loss of light, powdering, cracking, turbidity, blistering, embrittlement, strength decay and oxidation.Widely used in paint, resin, plastic, printing and packaging, aluminum profiles, adhesives, automobile and motorcycle industry, cosmetics, metal, electronics, electroplating, medicine, etc.
