Why Choose UVA 340 Fluorescent Lamp for UV Aging Tests
Accurate Solar Simulation (295–365 nm)
Closely matches the short-wave UV portion of natural sunlight, especially critical for polymer degradation studies.
Peak Wavelength at 340 nm
Perfect for simulating sunlight-induced aging such as fading, yellowing, cracking, and chalking.
Stable Irradiance Output
Maintains consistent UV intensity over long test cycles, ensuring reliable and repeatable results.
Long Service Life (>5000 hours)
Reduces replacement frequency and operational cost for testing laboratories.
Wide Industry Compatibility
Suitable for coatings, plastics, inks, adhesives, rubber, and automotive materials.
This makes UVA 340 lamps the preferred choice for standards such as ASTM G154 UV testing.

Related Test Equipment - UV Aging Chamber
UV aging chamber tests the performance of the product in the ultraviolet environment.
Structural composition
Control system:
Precise regulation, monitoring of lighting, temperature and humidity, spray and other parameters, intelligent programming, record and store data.
It can also display the current of the UV lamp to remind the user to replace the new lamp according to the lamp status
Sample test area:
Standardized flat aluminum plate type sample holder with ring, or customized 3D sample holder.
Spray system:
Simulate rainfall, spray water evenly, spray time and interval can be adjusted as needed, and the sample surface can be cleaned.
Lighting system:
8 UV lamps, four lamps on each side.
Heating system:
Sink type heating, heating stability
Humidity system:
The flume heating system allows steam to rise and increases humidity in the workroom.
Working principle
The use of high-intensity UV lamps, combined with controlled temperature, high humidity and spray that can simulate dew deposition to accelerate aging tests of materials or other products at a speed far greater than that of natural environments.
