Easy and efficient human-machine dialogue: The intelligent architectural glass designed based on Windows environment can operate the software on light transmittance, shading coefficient and hemispheric emissivity, providing a wealth of instrument control and operation functions, which is simple and easy to use, flexible, efficient and easy. Meet users' analytical needs.

5. Excellent scalability: Optional special accessories for the reflective optical integrating sphere and special reflective devices for the shading coefficient of architectural glass greatly expand the application range of the instrument.

6. Equipment maintenance is simple and convenient: unique socket-type tungsten lamps and deuterium lamps eliminate the need for optical debugging when changing lamps, making debugging and maintenance of equipment and instruments simpler and more convenient. The vacuum press performs oil detection.

7. Logging function: Automatically record user operations; log files are saved in a more reliable database format; administrators can classify and review logs and perform other processing.

8. Adopt a comprehensive optical and hemispheric emission integrated device testing system, which is cost-effective and easy to test.

9. Quality control function: The measurement data can be monitored according to the user's settings; if the data exceeds the control range, the system will display prompt information, color mark or automatically re-measure.

10. Report output function: It can realize the function of sharing data with other systems; the measurement results can be saved in Microsoft Word format, Microsoft Excel format, and text file format; the report format can be personalized; the result report can be previewed in advance. Printing effect.
