UV-SE Descriptions:
UV Weather resistance test chamber is equipped with fluorescent UV lamp which can completely simulate the UV spectra of sunlight, exposes materials to alternating cycles of UV light and moisture at controlled, elevated temperatures. It simulates dew and rain with condensing humidity and/or water spray.
UV Weather resistance test chamber is the world's most widely used weathering tester to test types of damages include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, strength loss and oxidation.
UV Models
Model UV/basic
UV/basic uses fluorescent UV lamps and a condensation system for moisture simulation, does not include the SOLAR EYE irradiance control.
Model UV/se
UV/se is the most popular model features the SOLAR EYE Irradiance Control, for precise maintenance of UV light intensity. The UV/se tester uses a proven condensation mechanism to simulate outdoor moisture attack.
Model UV/spray
The UV/spray has the same functions as a standard UV/se, but also includes a water spray system. Short periods of spray can be used to create a thermal shock. Longer periods can be used to achieve mechanical erosion.
Model UV/cw
Some industry test methods specify the use of cool white fluorescent lamps for indoor photostability testing. To reproduce these indoor light conditions, the UV/cw uses ordinary cool white fluorescent lamps. It has a SOLAR EYE irradiance control system that monitors and controls visible light output, rather than UV.

UVB-313EL: Suitable for the quality control and research, development applications, recommended for the testing of some durable materials, such as roofing paint.
QFS-40 (F40 UVB): Test the vehicle exterior paint.
UVA-351: Suitable for the glass solar UV simulation, Recommended for use in automotive interior parts, textiles and ink testing.
The SOLAR EYE system
Most UV Accelerated Weathering Test Chambers are equipped with solar eye irradiance control. It is a precision control system that automatically maintains light intensity through a feedback loop. The controller monitors UV intensity and compensates for lamp aging and variability by adjusting power to the lamps.
Controls Irradiance
1, Monitors light intensity
2, Maintains preprogrammed intensity
3, Maximizes repeatability & reproducibility
Extends lamp Life
4, Operates lamps until set point can't be maintained
5, Reduces maintenance
Accelerate Results
6, maximizes effects with high irradiance
7, operates at 75% higher irradiance than noon, summer sunlight
