WSF-J Spectroscopical Color photometer |
|
| Characteristics: |
| * 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 (380nm-760nm), 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. |
