1, obtain measurement certification; Instrument built-in sensor, information processing chip; Ensure the accurate transmission of optical signal and the stability of electrical signal, for the accuracy and repeatability of the instrument , display accuracy 0.01, repetition accuracy △E standard deviation value 0.08. 2, L*a*b, L*c*h, Yxy and other multi-color space color value display; As a general-purpose measuring instrument, the color difference meter has a built-in program to convert the color display indicators, so that the instrument can be directly applied to a variety of color measurement fields, without the need for color measurement personnel to manually convert the measurement data, which greatly improves the work efficiency. 3, can achieve yellow, white test; Whiteness value: ASTM whiteness, Gantz whiteness; Yellowness value: YI 4. Ergonomic design; The waist of the instrument conforms to the arc of the human hand, which can carry out long-term detection work; Master sensory cortex design, increase friction, prevent fingers from slipping. 5, free color management software real-time display qualified or not, print test reports, save each batch of color data, suitable for enterprise internal and external color evaluation and data control;, Manufacturer: ZXZZAS
