50mm large aperture

Measuring aperture up to 50mm, especially suitable for color difference measurement of objects with rough surfaces such as masterbatches, powders and rough fabric.

Display of spectral reflectance curves

Using full-spectrum LED light source and advanced spectral sensors to provide professional spectral reflectance curves, providing more professional color data for color measurement, from which information such as hue, saturation, depth, etc. can be obtained

Good repeatability, △E*ab≤0.03

High precision and excellent repeatability with standard deviation △E*ab≤0.03. It can pass the test of authoritative metrology institute.

Free special plastic cuvettes

It is equipped with special plastic cuvettes for the measurement of masterbatches, powder and opaque liquid.

Simple operation, two-step color difference measurement

Measure color difference with two clicks on the 7-inch color touch screen for extremely simple operation.

Provide QC function

It has QC function which can set the color difference threshold by yourselves, and it will automatically judge whether the color difference is qualified or not.

Multiple parameters measurement

Multi parameters including CIE Lab, Luv, LCh, Yxy, CMYK, RGB, WI-98, WI-Gauz, WI-Hunter, YI-98, WI-R457, Spectral reflectance curve.
