HY4420 Ultraviolet Accelerated Weatherometer is used to simulate ultraviolet radiation, rain spraying, condensation, temperature and humidity environment for accelerated ageing test of textile, rubber, plastic, paint, coating and other product. It adopts UV lamp as light source. This instrument complies with the following international and industry standards. ISO: ISO 1431. BS: BS EN 12224. GB/T: GB/T 7762. Imported UV lamp, ballast, starter and solid-state relay. 304 SUS stainless steel casing. Air duct in the chamber adopts single cycle system to improve the air flow, heating capacity and the uniformity of temperature in the chamber. Real-time display running time, running phases, remaining time; can display test data, including set temperature, current temperature, total running time, running time of current phase, remaining time of current phase, heating condition, calendar time, etc.; digital display temperature. Several alarm function: absolute value alarm, deviation alarm. Control system adopts zero passage triggering through solid-state relay, low noise, less pollution, easy to maintain, high control accuracy.
