Drawell Spectroscopical Color Spectrophotometer (DW-WSF)

DW-WSF Spectroscopical Color photometer
 
CharacteristicsWide 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 (400nm-700nm), 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.SpecificationsLighting conditions: d/0Spectrum 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.RS232Measurement window: Ø20mm  Wavelength range: 400nm~700nm;  Accuracy: ±2nmAccuracy of spectrum transmittance (%):±1.5Repeatability: σ u (Y) ≤0.5, σ u (x),σ u (y) ≤0.003Instrument stability: ΔY≤0.6Accuracy: ΔY≤2, Δx,Δy≤0.02Palette system:Color: X, Y, Z; Y, x, y; L*, a*, b*; L, a, b; L*, u*, v*; L*, c*, h*Color difference: Δ E (L*a*b*); ΔE (Lab); ΔE (L*u*v*);  ΔL*, ΔC*, ΔH*Whiteness: Gans whiteness

             Blu-ray whiteness: W=B
             Tabble: W=4B-3G
