Sun Simulation Chambers - Sunlight Radiation Accelerated Aging Equipment for Accelerated Weather Testing
The simulation of natural sunlight is achieved by using several different methods based on the area of the spectrum it is required to test, in order to check the damage caused by the differing solar radiations. The main applications are the accelerated aging of the equipment under the effects of the radiation combined with other environmental phenomena such as temperature, humidity, rain, corrosion and so on. Several kinds of lamps can be used:
• Metal halide lamps able to cover the whole spectrum of the sun’s radiation
• Ultraviolet lamps to test the equipment against damage due to UV rays
Application
It is widely used in paint, resins, plastics, printing and
packaging, aluminum, adhesives, auto, cosmetics, metals,
electronics, electroplating, medicine, etc.

※ Digital meter shows vibration frequency
※ Synchronous squelch belt drive, extremely low noise
※ The sample is clamped by rail, which is easy to operate and safe.
※ The base of the machine is made of heavy-duty channel steel with vibration-damping pad. It is easy to install and runs smoothly. No need to install anchor screws.
※ DC motor speed regulation, stable operation, strong load capacity
※ Rotary vibration (commonly known as horse racing), in line with European and American transportation standards
