Product introduction

DRK103C Automatic chroma meter is a new instrument developed

by our company in the industry's first fully automatic key determination

of all colors and brightness parameters, widely used in papermaking,    printing, textile printing and dyeing, chemical industry, building materials, ceramic enamel, grain, salt and other industries, for the determination of

the object's whiteness and yellowness, color and color difference,

can also be measured paper opacity, transparency, light scattering coefficient, absorption coefficient and ink absorption value.

Product features

(1)5 inch TFT color LCD touch screen, the operation is more humanized, new users can be mastered in a short period of time using the method

(2) Simulation of D65 lighting lighting, using CIE1964 complementary color system and CIE1976 (L*a*b*) color    space color difference formula

(3)The motherboard brand new design, using the latest technology, CPU uses 32 bits ARM processor,improve    the processing speed, the calculated data is more accurate and rapid electromechanical integration design,    abandon cumbersome testing process of the artificial hand wheel is rotated, the real implementation of the    test program, a determination of the accurate and efficient

(4) Using d/o lighting and observation geometry, diffuse ball diameter 150mm, diameter of the testing hole is     25mm

(5)  A light absorber, eliminate the effect of specular reflection

(6)Add printer and imported thermal printer, without the use of ink and color, no noise when working, fast   printing speed

(7) Reference sample can be physical, but also for data,? Can store up to ten only memory reference   information

(8) Has the memory function, even if the long-term shutdown loss of power, memory zeroing, calibration,  standard sample and a reference sample values of the useful information is not lost  

(9) Equipped with a standard RS232 interface, can communicate with computer software

Product application

(1)Determination of object color and color difference, report diffuse reflectance factor Rx, Ry, Rz, X10, Y10, Z10 tristimulus values, chromaticity coordinates X10, Y10, L*, a*, b* lightness, chroma, saturation, hue angle C*ab, h*ab, D main wavelength, excitation purity of Pe, chroma difference ΔE*ab, lightness difference Δ L*.  chroma difference ΔC*ab, hue difference Δ H*ab, Hunter L, a, b

(2) CIE (1982) determination of whiteness (Gantz visual whiteness) W10 and partial Tw10 color value

 (3)Determination of whiteness of ISO (R457 ray brightness) and Z whiteness (Rz)

 (4)Determine the phosphor emission fluorescent whitening degree

 (5) WJ Determination of whiteness of building materials and non-metallic mineral products

(6) Determination of whiteness Hunter WH

(7)  Determination of yellow YI, opacity, light scattering coefficient S, OP optical absorption coefficient A,    transparency, ink absorption value

(8)Measurement of optical density reflection? Dy, Dz (lead concentration)
