Product features
To measure the Blue Reflectance Factor (R457) of samples. Blue Reflectance Factor is so called “Blue Whiteness” or “ISO Brightness”. Adopt d/o illuminating--geometrical viewing conditions. Diameter of the globe of diffusion is 150mm and diameter of the testing hole is 30mm. Light absorber is provide to eliminate the effect of mirror reflection. 10 successive test data auto-calculates mean value With power-off protection function to protect data The appearance of this instrument is novel and compact and the advanced circuit design effectively guarantees the accuracy and stability of the measurement data. The instrument is equipped with a standard RS232 interface which can cooperate with the computer software for communication.
