ZB A Automatic colorimeter

Product Overview

Description

ZB-A Automatic colorimeter

Introduction

ZB-A Automatic colorimeter is to determine the whiteness, yellowness, color and color difference of the object, but also can determine the paper's opacity, transparency, light scattering coefficient, light absorption coefficient and ink absorption value.Widely used in papermaking, printing, ceramics, chemical industry, textile printing and dyeing, building materials, grain, salt and other industries.

The specific functions of the instrument are as follows:

1. Measure the reflected color and chromatic aberration of the object, which can be displayed or printed: diffuse reflection factor Rx, Ry, Rz, stimulus value Y10, X10, Z10, color coordinate X10, Y10;Lightness L *, a * chromaticity, b *, chroma C * ab, hue Angle h * ab, dominant wavelength lambda d, excited purity, Pe Δ E * ab color, brightness difference Δ L *, chroma difference Δ ab, poor tonal Δ h C * * ab, hunter system L, a and b.

2. Measurement of ISO brightness (blue light whiteness R457) and Z whiteness (Rz) can be used to measure fluorescence whiteness generated by emission of fluorescent substances in fluorescent whiteness samples. 

3. Measurement of CIE whiteness (gantz whiteness W10 and deviation TW10).

4. Measure the whiteness of ceramics.   

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

6. Measure hunter whiteness WH.

7. Measure the yellow degree YI.     

8. Measure the opacity OP of the sample

9. Measure the transparency T of the sample

10. Light scattering coefficient S of the measured sample

11. Optical absorption coefficient A of the sample was measured.     

12. Measure ink absorption.
