Product Introduction

Whiteness colorimeter, also known as colorimeter, whiteness colorimeter, whiteness colorimeter, etc., can be widely used in industries such as papermaking, printing, ceramics, chemical industry, textile printing and dyeing, building materials, grain, salt production, etc., to determine the whiteness, yellowness, color and color difference of objects.

Product Features

The instrument adopts integrated technology of light, machine, and electricity, as well as microcomputer measurement and control technology. It has the function of statistical processing of test data, can print and output, and can measure the whiteness (brightness) and chromaticity of various objects.
1. Measure the color of the object, report diffuse reflectance factors RX, RY, Rz, stimulus values X10, Y10, Z10, chromaticity coordinates X10, Y10, brightness L *, chromaticity a b *, chroma C * ab, hue angle h * ab, dominant wavelength λ d, excitation purity Pe, color difference Δ E * ab, brightness difference Δ L, chroma difference Δ C * ab, hue difference Δ H * ab, Hunter system L, a, b;
2. Measure the yellowness YI;
3. Measure the opacity OP;
4. Measure the light scattering coefficient S;
5. Measure the light absorption coefficient A;
6. Measure transparency;
7. Measure the ink absorption value;
8. The reference sample can be a physical object or data. The instrument can store and remember up to ten reference sample information;
9. Multiple measurements can be averaged; Digital display and printable report of measurement results;
10. The instrument has a memory function. Even if the device is shut down for a long time and loses power, useful information such as memory zeroing, calibration, and measurement values of standard and reference samples will not be lost

Product Application

1. Measure the color and color difference reflected by objects

2. Measure ISO brightness (blue light whiteness R457) and the fluorescence whitening degree of fluorescent whitening materials

3. Measure CIE whiteness (Ganz whiteness W10 and color deviation TW10)

4. Measure the whiteness of building materials and non-metallic mineral products

5. Measure the yellowness

6. Measure the opacity of the sample Transparency Light scattering coefficient and light absorption coefficient

7. Measure the ink absorption value
