Technical Core and Light Source Characteristics of Salt Spray Test Chamber and Tabletop Xenon Lamp Test Chamber

The Skill Center and Light Source Characteristics of Desktop Xenon Lamp Test Chamber: The desktop xenon lamp salt spray test chamber can actively monitor the temperature; it is equipped with a radiometer that can stabilize the voltage through a voltage rectifier to adjust the light irradiance, stabilizing the irradiance at the designated level while controlling the experimental time. By simulating the ultraviolet radiation in natural sunlight, accelerated weathering tests are conducted on materials to obtain results regarding their weather resistance.

The light source of the desktop xenon lamp test chamber uses a visible xenon lamp with a rated power of 2500W. The lamp tube is installed at the top layer inside the instrument, with the emitted light spectrum energy concentrated primarily between 300~780nm wavelengths.

According to the experimental spectral irradiance, it should not exceed 1~3 times the corresponding solar (average summer equatorial noon) irradiance.

Since the energy output of fluorescent lamps will gradually decrease over time, in order to reduce the impact on the experiment caused by the attenuation of light energy, and to meet the requirement of GB/T19394-2003 No.5-a for irradiance uniformity ±15%, this test chamber is designed with adjustable height for sample testing pieces.
