Spectrophotometer

Product IntroductionThe WSF spectrophotometer is a high-performance, versatile, and easy-to-use colorimeter. Suitable for measuring the reflection and transmission colors of various objects, it can test the whiteness, chromaticity, and color difference of objects. The illumination receiving method of the instrument is d/0 as specified by CIE. It can display the reflectance and transmittance of objects in the visible light band (400nm~700nm), and can communicate with a computer through an interface to provide the spectral curve of object reflectance color, greatly facilitating the analysis of object color.
This instrument can be widely used in industries such as textiles, dyes, printing and dyeing, coatings, paints, papermaking, building materials, food, printing, etc.
