Product Description Brightness and Color Tester is a detection instrument for measuring the color, chromatic aberration and whiteness of objects based on the principle of light reflection. Product Description Product FeaturesAdvanced circuit design effectively guarantees the accuracy and stability of the measurement dataCan store ten reference samples as well as power-off protection, automatically save calibration data if power outage.Standard RS232 interface, with computer software for communication (Purchased separately) Product FunctionMeasure the color and chromatic aberration reflected by the objectMeasure D65 brightness (R457 blue light whiteness)Measure the degree of fluorescent whitening produced by the emission of fluorescent substances (the sample contains fluorescent whitening agent)Measure CIE whiteness (Gantz whiteness W10 and color cast value TW10)Measure the whiteness of ceramics, building materials and non-metallic mineral productsMeasure Hunter System Lab and Hunter (Lab) whitenessMeasure yellowness, ink absorption valueMeasure the opacity, transparency, light scattering coefficient and light absorption coefficient of the sampleApplication RangePaper, cardboard, pulp, ceramics; Cement, starch, calcium carbonate, talc and other powders.Executive StandardGB/T 7973,GB/T 7974,GB/T 7975,GB/T 8940.2,GB/T 1840,GB/T 13025,GB/T5950GB/T 9338,GB/T 4739,GB/T 1543,GB/T 10339,GB/T 12911,ISO 2470,ISO 2471Sales And Service NetworkTechnical Parameters No.Parameter itemTechnical index1Power Supply AC(100~240)V,(50/60)Hz,50W2Working EnvironmentTemperature(10~35)oC, Humidity≤ 85%3Display 240X128 dot matrix LCD screen4Light sourceAnalog D655Integrating sphereDiameter 150mm6Sample SizeTest plate diameter ≥φ30mm while sample thickness≤40mm7Resolution ratioChromaticity Coordinate 0.0001,others 0.018Zero Drift ≤0.19Indicating Drift ≤0.110Indication accuracyChromaticity coordinates≤0.01,R457≤0.5Y≤1.011RepeatabilityR457≤0.1, chromaticity coordinates≤0.001,Y≤0.1,△E≤0.212Specular Reflectance Accuracy≤0.213PrintBuilt-in thermal printer14Communication InterfaceRS232(optional)15Dimension390×260×400 mm16Net Weight14.5kg around Recommend Products Company Profile
