Architectural glass shading coefficient testerMain Features
1. Strong instrument performance: Extremely excellent optical system, advanced electronic system, high-level mechanical system, ensuring ultra-low stray light of 0.010% T, high-precision PID temperature control and 24 bit voltage digital sampling.

2. Stable and reliable quality: The dual beam dynamic feedback proportional recording metering system ensures baseline stability, and key components such as deuterium lamps and photomultiplier tubes are imported to ensure the stability, reliability, and long lifespan of the instrument.

3. Accurate measurement: Using imported high-quality holographic gratings, further reducing the instrument's stray light and making the instrument analysis more accurate.

4. Easy and efficient human-machine dialogue: designed based on the Windows environmentGAF-Dseriesintelligent typeArchitectural glass canseeThe Chinese operation software for light transmittance, shading coefficient, coating solar reflectance, hemispherical emissivity, and equivalent thermal resistance provides rich instrument control and operation functions, simple and easy to use, flexible and efficient, and easily meets the analysis needs of users.

5. Excellent scalability: The reflective optical integrating sphere can be equipped with special accessories and a dedicated reflective device for building glass shading coefficient, greatly expanding the application range of the instrument.

6. Easy and convenient equipment maintenance: The socket type tungsten lamp and deuterium lamp of * eliminate optical debugging when replacing the lamp, making equipment instrument debugging and maintenance simpler and more convenient. The vacuum press is used for oil detection.

7. Logging function: Automatically record user actions; The log files are saved in a more reliable database format; Administrators can categorize and review logs for other processing purposes.
8. Adopting a comprehensive optical and hemispherical emission integrated testing system, with high cost-effectiveness and ease of testing.
9. Quality control function: can monitor measurement data according to user settings; Data systems that exceed the control range will display prompt messages, perform color labeling, or automatically remeasure.
10. Report output function: capable of sharing data with other systems; The measurement results can be saved in Microsoft Word format, Microsoft Excel format, or text file format; Personalized settings can be made for the report format; You can preview the printing effect of the result report in advance.
