UV Exposure Test Machine

Name: UV Exposure Test Machine
Brand: Xi'an LIB Environmental Simulation Industry

The UV exposure test machine can reproduce the aging phenomena of materials after long-term outdoor exposure, such as fading, cracking and strength reduction, in a short time. By simulating the radiation environment of the ultraviolet part in sunlight, controlling the light intensity, temperature, humidity and cycle mode, the accelerated aging of the material's UV resistance performance is evaluated.

LIB UV exposure test machine is often used in the research and development and quality control of fields such as plastics, coatings, rubber and textiles.

Model: UV-SI-260

Standard: ISO 4892-3, ISO 11507,ASTM G154,ASTM D4329,JIS D0205

Features and Benefits of UV Exposure Test Machine

1. Accelerated aging testing can simulate the aging effect of materials in natural environments for years within tens or hundreds of hours, accelerating the detection of materials' UV and weather resistance.

2. The UVA-340 or UVB-313 tubes, and the output wavelengths are concentrated around 340 nm or 313 nm respectively, which complies with standards such as ASTM G154 and ISO 4892-3.

3. The temperature can be controlled. It is also equipped with condensation and water spray functions to simulate the real day-night temperature difference and humidity cycle.

4. Supports light/condensation cycle, effectively simulating the alternating environment of direct sunlight during the day and high humidity condensation at night outdoors, accelerating the detection of surface aging, cracking and fading.

Details of UV Exposure Test Machine


UV tubes	Black Panel
A combination of 8 QUVA and QUVB tubes.The lifespan is up to 1,600 hours, and the automatic irradiation intensity compensation system can maintain the consistency of light intensity during long-term testing.	Install on the same plane as the sample, ensuring that the measured temperature is representative.It represents the highest temperature that the material surface may reach. Adjust within the range of 35°C to 80°C.

Spray System	Controller
There are five nozzles on each side, simulating processes such as rainfall and cooling in the natural environment to accelerate the aging of materials in the humid cycle. The spray mode can be set.	The programmable touch screen controller (PLC control) can control and display various parameters in real time, and has an alarm function.

Heater Tubes	Water Tank
Two types of heating tubes: temperature and humidity. The humidity heating tube is circular and placed in water. After heating, it generates steam. The temperature heating tube directly heats the bottom of the workroom.	Serves as the water supply source for the spray system and humidity control. It is a large-capacity water tank made of SUS304 material, equipped with a water circulation system and a water filtration system to prevent nozzle clogging.

The LIB UV exposure test machine enjoys a 3-year warranty, lifetime service, 24/7 technical support, and also supports various customizations to provide you with tailor-made solutions.
