LABO LB-48A Colorimeter tests whiteness, yellowness, Transparency, color difference

Introduction

The chromaticity Tester is used to measure the whiteness, yellowness, color and color difference of objects, and can also measure the opacity, transparency, light scattering coefficient, light absorption coefficient and ink absorption value of paper.

Application

Widely used in papermaking, printing, textile printing and dyeing industries.

Features

1. Measure the color and color difference reflected by the object, which can be displayed or printed: diffuse reflection factors Rx, Ry, Rz, stimulus values Y10, X10, Z10, chromaticity coordinates x10, y10, z10; lightness L*, chroma a*, b*, saturation C*ab, hue angle h*ab, dominant wavelength λd, excitation purity Pe, color difference ΔE*ab, lightness difference ΔL*, saturation difference ΔC*ab, hue difference ΔH*ab, Hunter system L , a, b

2. Measure the ISO brightness (blue light whiteness R457) and Z whiteness (Rz), which can measure the fluorescent whitening degree produced by the emission of fluorescent substances in the fluorescent whitening sample

3. Measure CIE whiteness (Gantz whiteness W10 and color cast value TW10) 4. Measure ceramic whiteness 5. Measure whiteness of building materials and non-metallic mineral products 6. Measure Hunter whiteness WH

7. Measure yellowness YI

8. Measure the opacity OP of the sample

9. Measure the transparency T of the sample

10. Measure the light scattering coefficient S of the sample

11. Measure the light absorption coefficient A of the sample

12. Measure the ink absorption value

feature of product

• The appearance of the instrument is novel and compact, and the professional circuit design effectively guarantees the accuracy and stability of the measurement data.

• The instrument simulates D65 illuminant illumination. Adopt CIE 1964 supplementary chromaticity system and CIE 1976 (L*a*b*) color space color difference formula. 

• The instrument adopts d/o illumination to observe geometric conditions. The diameter of the diffusion ball is 150mm, and the diameter of the test hole is 30mm. It is equipped with a light absorber to eliminate the influence of the specular reflection of the sample. 

• Large-screen high-pixel liquid crystal display module, Chinese display and prompt operation steps to display measurement and statistical results, friendly man-machine interface makes the operation of the instrument simple and convenient. 

• The instrument adds a printer and adopts imported thermal printing core, no need to use ink and ribbon, no noise when working, and fast printing speed.

• The instrument is equipped with a standard RS232 interface, which can communicate with computer software. 

• The instrument has power-off protection, and the calibration data will not be lost after power-off.

• Can store 9 reference samples.
