Papermaking, printing, textile printing and dyeing, ceramics, building materials, chemicals, grain, salt and other industries and other production and commodity inspection departments that need to determine the color and whiteness of solids.

● Determine the color and color difference of solids under C light source and D65 light source conditions:
● CIE1931 tristimulus values and chromaticity coordinates under standard chromaticity system;
● CIE1964 supplement the standard chromaticity system with tristimulus values and chromaticity coordinates;
● CIE1976 L*, u*, v*, C*uv, Suv, huv, a*, b*, C*ab, hab and color difference in uniform color space.
● Determine CIE whiteness W10 (Gantz visual whiteness) and skew value Tw10
● Measure the brightness of the blue diffuse reflection factor D65 and the fluorescence brightness of the fluorescent brightening material.
● Measure the ISO brightness at C/2° indoor light and the fluorescence brightness of the fluorescent brightening material.
● Determine the whiteness and color of building materials, non-metallic mineral products and ceramics.
● Determine whiteness, Lab and color difference under Hunter system.
● Determine the whiteness and chromaticity of the fiber (with fiber sampler).
● Measure the whiteness, chromaticity Lab and color difference of the powder.
● Measure yellowness YI, opacity OP, light scattering coefficient S, light absorption coefficient A, transparency, ink absorption value.
● Measure the reflected optical density Dx, Dy, Dz.

● Imported concave flat field grating, photoelectric display sensor, pulsed xenon lamp and other parts, to ensure the accuracy of the equipment basis.
● Cotex-M4 ARM processor
● Stepper motor control UV radiation, automatic and accurate control of radiation, fluorescence brightness one-key test.
● Test data can be exported from USB flash drive.
● The system and screen software can be upgraded through the network or USB flash drive.
● Supports a variety of communication methods, online software (purchased separately) can be WIFI or USB communication.
● Test data can be uploaded to the cloud server, and cooperate with the QMS paper quality management system (purchased separately) to monitor the paper test data in real time.
● The instrument is equipped with touch screen as standard, which can operate in two modes: touch screen operation and PC software operation. Convenient for users to choose. Touch screen operation is fast and rapid; PC software operation, test data storage space is not limited, easy access and print historical measurement data, the number of standard samples is not limited.
