(1)Wide application range and easy-to-operate feature.

(2)Measure reflection color and transmission color of objects and can test chromaticity, whiteness and color difference between two objects or two kinds of liquid.

(3)Only accept d/0 lighting specified by CIE.

(4)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.

(5)Wide used in such industries as textile, dye, printing and dyeing, coating, paint, paper making, building materials, food, and printing.

(1)Lighting conditions: d/0

(2)Spectrum conditions: overall response is equivalent to tristimulus values X, Y, and Z calculated in corresponding functions under GB3978 standard illuminant D65, A, C and 10°, 2° view of field.

(3)RS232

(4)Measurement window: ?20mm
