WSC-S color measuring colorimeter is a color measuring meter with superior performance, wide use and convenient operation. It is suitable for measuring the reflected color of various objects. It can test the whiteness, chromaticity and color difference of two kinds of objects. It is equipped with the test head of geometric conditions, namely 0/d specified by CIE. WSC-S color measurement colorimeter is a desktop portable two-purpose, digital display, and printable. The instrument can be widely used in textiles, dyes, printing and dyeing, papermaking, building materials, enamel, food, printing, measurement and other departments. The main technical parameters: Instrument lighting geometric conditions: 0 / d Spectral conditions, the overall response is equivalent to the tristimulus value X10Y10Z10 under the CIE standard illuminator D65 and 10° field of view color matching function (hereinafter abbreviated as X, Y, Z) Irradiated sample area: Φ20 Display mode: digital display printout Color system (l) Color: X, Y, Z; Y, x, y; L *, a*, b *; L, a, b; L*, u*, v*; L*, c*, h; λd , Pe; (2) Color difference: ΔE (L* a* b*); ΔE (L a b); ΔE (L*u* v*); ΔL*, Δ*, ΔH*; (3) White: (a) Gantz whiteness: binary linear whiteness recommended by CIE (b) Blue light whiteness: W = B (C) Tabble: recommended by ASTM, W=4B-3G (d) Reflective whiteness of R457 Repeatability: δu(Y)≤0.2, δu(x)≤0.003, δu(y)≤0.003 Stability: ΔY≤0.6 Power supply: 220 V ±22V, 50 Hz ±1Hz Dimensions: host 410mm×370mm×160mm Test head Φ120 mm×170mm Net weight of the instrument: 17kg Output communication interface: RS232
