Ообзор

White/Brightness tester is to determine the whiteness, yellowness, color and color difference of the object, but also can determine the opacity of paper, transparency, light scattering coefficient, light absorption coefficient and ink absorption value.Widely used in papermaking, печать, керамика, химическая индустрия, textile printing and dyeing, строительные материалы, зерно, salt and other industries.

Equipment function:

1.Measure the reflected color and color difference of the object, which can be displayed or printed: diffuse reflection factors Rx, Рай, Рз, stimulus values Y10, X10, Z10, chromaticity coordinates X10, Y10, Z10;Lightness L *, а * chromaticity, б *, 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.The ISO brightness (blue light whiteness R457) and Z whiteness (Рз) can be measured to measure the fluorescence whiteness generated by emission of fluorescent substances in the fluorescence whitening samples.

3.CIE whiteness (Gantz whiteness W10 and color TW10) was measured.

4.Measure the whiteness of ceramics.

5.Measure the whiteness of building materials and non-metallic minerals.

6.Measure hunter whiteness WH.

7.Measure yellow YI.

8.OP of opacity of test sample

9.Measure the transparency T of the sample

10.The light scattering coefficient S of the sample was measured

11.Measure the light absorption coefficient A of the sample.

12.Measure ink absorption value.

Main performance parameters

  1. The instrument has novel appearance and compact structure, and advanced circuit design effectively ensures the accuracy and stability of measurement data.
  2. The instrument simulates D65 illumination.CIE 1964 supplementary chroma system and CIE 1976 (L* A * Б *) chromatic space chromatic aberration formula were used.
  3. The instrument adopts D/O illumination to observe the geometric conditions.The diameter of the diffuse ball is 150mm, the diameter of the test hole is 30mm, and the light absorber is provided to eliminate the influence of the specular reflection of the sample.
  4. LCD module with large screen and high pixels is adopted to display measurement and statistical results in Chinese with prompts for operating steps. Friendly man-machine interface makes the operation of the instrument simple and convenient
  5. The instrument adds a printer and adopts imported thermal printing movement, no need to use ink and ribbon, no noise when working, fast printing speed and other characteristics
  6. The instrument is equipped with standard RS232 interface, which can communicate with microcomputer software
  7. The instrument is protected by power off, and the calibration data will not be lost after power off
  8. Can store 9 reference samples.
