Introduction

WS177 large aperture spectrocolorimeter adopts D/8 illumination geometry, with 50mm large test aperture, 

specialized in color measurement and color comparison of non-transparent materials such as powder, masterbatches and so on. 

The spectrocolorimeter not only has various  color spaces and color difference formulas, but also can display spectral reflectance curves, 

which is widely used in color management and quality control in the fields of paint, plastic, food, medicine and so on. 

The colorimeter  also provides professional mobile APP and PC software to support data export and report printing.

Features

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;

Good repeatability, △E*ab≤0.03;

imple operation, two-step color difference measurement;

Built-in multiple universal electronic color charts;

Cell phone App is more functional;

Provide PC software, support data import and export.
