Characteristic：
WSF spectrophotometer is a kind of superior performance, convenient operation and wide use of color measurement instrument. The reflection and transmission of color color is suitable for measuring various objects, can test the whiteness and chromaticity and color difference of two objects. The lighting instrument receiving mode is specified in CIE d/0. It can be shown that the visible band (400nm~700nm) of objects in the reflectance and transmittance, and through the interface with the computer communications, give the object spectral curve of the reflection color, greatly facilitate the analysis of the color of objects. this The instrument can be widely used in textile, printing and dyeing, dye, paint, paint, paper, building materials, food, printing and other industries.
