Especificações
Wide application range and easy-to-operate feature;
Measure reflection color and transmission color of objects and can test chromaticity, whiteness and color difference between two objects or two kinds of liquid;
Only accept d/0 lighting specified by CIE;
Display reflectance and transmittance of objects or liquid within the scope of visible light wave (400nm-700nm), and generate a spectral curve on reflectance and transmittance of objects or liquid, which greatly facilitates analysis on object color;
Wide used in such industries as textile, dye, printing and dyeing, coating, paint, paper making, building materials, food, and printing.
