nineIntroduction to functional areas

9.1.Irradiation system(Simulating sunlight)

light source6The rated power isA 40W imported ultraviolet fluorescent lamp with UVA-340 and UVB-313 light sources for users to choose from and configure. like

Like other light tubes,The aging of UV lamps can lead to a decrease in lamp output, and there is no sun eye control system to rotate the position of UV use

The method to compensate. This system can be used for many application standards, but it has inherent limitations. This method of rotating positions

The law cannot compensate for the impact caused by different batches of lamps or different surrounding environments.

9.2.Solar Eye System

Changes in light intensity can affect the rate of material aging, while differences in spectra may simultaneously affect both the rate and type of material aging

Create an impact. Accurate and reproducible test results can only be obtained by controlling irradiance through the solar eye system.

The solar eye system is a precise closed-loop control system that can automatically maintain the set light intensity through a feedback loop. controller

It can continuously monitor the intensity of ultraviolet light and compensate for any aging or other factors caused by the lamp by adjusting the output of the lamp

Changes in light intensity. The reproducibility and repeatability of the test results of the solar eye irradiance control system are better than those of manual irradiance control, and

Can effectively extend the lifespan of the lamp tube. The sun eye is installed in the distribution cabinetUVloopIn the middle, there is a group of two solar eye monitoring devices

The light intensity of the lamp tube is measured and the data is transmitted to the controller. The controller compares the measured irradiance value with the set value and then controls

The device commands the power system to adjust the output of the lamp tube to maintain the set light intensity value.

Guide to fill the entire laboratory.

9.6Condensation system(Simulated Dew)

The condensation system is essentially the evaporation of water vapor confined within the experimental chamber by the sample of the experimental chamber. During the condensation cycle, water passes through

The heating element in the plate heats up, and water vapor fills the test chamber100%When the humidity reaches equilibrium, water vapor continuously condenses on the sample

Finally, it flows back into the water tray.
