WSF spectrophotometer

Features:
The WSF Spectrophotometer is a color measuring instrument with superior performance, versatility and easy operation. It is suitable for measuring the reflection color and transmission color of various objects. It can test the whiteness, chromaticity and chromatic aberration of two objects. The illumination receiving mode of the instrument is d/0 specified by CIE. It can display the reflectance and transmittance of objects in the visible light band (400nm~700nm), and can communicate with the computer through the interface to give the spectral curve of the reflected color of the object, which greatly facilitates the analysis of the color of the object. The instrument can be widely used in textile, dye, printing and dyeing, coating, paint, paper, building materials, food, printing and other industries.
