Ⅰ. Small Xenon Test Chamber:

Compared with XD-21-865, XD-21-866 adds spray function. Spray function is used to simulate rain and humidity when the material is used at outdoor. Furthermore, operator can set the cumulative energy （Total irradiance energy）obtained by sample to stop a test procedure.   
Operator can set all required test parameters （Irradiance, test time, BPT etc）through the touch screen, and can check its running status at any time. All running parameters can be exported to computer through the USB interface.

working principle

Ⅱ. Characters:

◆ The Xenon light source correspond with international standards; ensure reproducibility and comparability of testing results.
◆ Optional light-filters can meet the requirements of many international standards.
◆ Small Size, easy to install, use and practically maintenance-free.
◆ Touch screen and user-friendly operation interface allow handlers set the test parameters and monitor all the test process easily.
◆ Specimen mounting and evaluationis fast and easy because of unique slide-out specimen tray
◆ Real-time data can be collected and recorded. The incidental USB connector allows users to copy the test data into a USB drive, achieving unattended operation.
◆ Irradiance energy can be accurately controlled. The "Solar Eye" control system can automatically 
compensate the change of light intensity caused by ageing or other factors.
◆ The test procedures can be programmed freely; and up to 6 predetermined procedures can be saved in one time.
 Every procedure includes up to 10 segments setting data.
◆ Users can easily calibrateand adjust the irradiance or the blackboard temperature by themselves.
◆ With high precision Pt100 Temperature sensor. Blackboard temperature is auto-controlled during the whole process
◆ Alarm function for protection：Over temperature, over heating load
