UV Weathering Test Chamber ISO 4892-1

UV Weathering Test Chamber exposes test sample to fluorescent UV lamps combined specified environmental conditions of dew and rain with condensing humidity and/or water spray to cause the damage in samples.

UV Aging Test Chamber can simulate the climatic conditions to reproduce the damage in short time within days or weeks, not months or years outdoors take.

The chameber is widely applied to test resistance to ultraviolet light aging for non-metallic material and organic materials such as  plastic, rubber, electronics, painting and related products.

Available Lamps:


UVA-340 Lamps

Best simulation of sunlight is given by UVA-340 lamps from UV Aging Tester with wavelength range from 365 nm to 295 nm.

UVA-351 Lamps 
UVA-351 lamps can simulate the UV portion of sunlight filtered behind window glass.  It is commonly used in internal applications to test some inks and for polymer damage occurred in an situation near a window. 

UVB-313 Lamps  
UVB-313 lamps are most useful for department of QC and R&D to discover most durable materials. It can accelerate utilizing short-wave UV at maximum degree that is more strict than common UV in the surface of earth. Finally, these lamps may case unrealistically serious effects on some materials. 


Features and Advantge of Labtech UV Weathering Aging Tester:


1) Easy to Operate

Color touch screen controller with simple user interface for easy operation. The test can be completed automatically after setting all required parameters in the controller. 


2) Temperature Control and Water Spray System

UV exposure with controlled temperature combined dew and rain with condensing humidity and/or water spray can accelerated test results and make sure test data accuracy. Temperature, water spray and condensation can be perfomed independently.
