UVN300Detection of visible light transmittance and shading coefficient of architectural glass
UVN300Visible light transmittance of architectural glass/Sunshade coefficient detector
Instrument Introduction
Visible light transmittance of architectural glass/The sunshade coefficient detector is based on the national standardGB/T2680-94Developed primarily forArchitectural glass testingThe instrument adopts imported core components, high-quality optical systems, and measurement technology to ensure high accuracy and stability of measurement results. Through multiple comparative tests with imported equipment of the same level (Shimadzu, Varian, Agilent), the test results have all reached the level of imported equipment. The instrument can automatically detect parameters such as visible light transmittance, direct sunlight transmittance, direct sunlight reflectance, total solar energy transmittance, and shading coefficient of various window glass components for solar radiation heat in building glass.
