Introduction
DRK103 Whiteness Meter is also called Whiteness Meter, whiteness Tester, etc. This instrument is used to determine the whiteness of objects, which is widely used in papermaking, textile, printing and dyeing, plastics, ceramics, ceramics, fish balls, grain, building materials, paints, chemicals, sales cotton, calcium carbonate, calcium bicarbonate, salt and other production and commodity inspection departments that need to determine the whiteness of the special body. The DRK103 Whiteness Meter can also determine the transparency, opacity, light scattering coefficient and absorption coefficient of paper.
Features
1. Measure ISO brightness (i.e., R457 whiteness), and the fluorescence whiteness produced by the emission of fluorescent substances can also be measured for the fluorescent whitening sample.
2. Measure the brightness stimulation value Y10. Determine Opacity. Determination of transparency. The light scattering coefficient and absorption coefficient are determined. 3. Simulate D65 illuminator lighting. The CIE 1964 supplemental chromaticity system and the CIE 1976 (L*a*b*) color space chromatic aberration formula were used. The geometric conditions were observed by D/O illumination. The diameter of the diffuser ball is φ150mm, and the diameter of the test hole is φ30mm and φ19mm, and there are two kinds of light absorbers, which eliminate the influence of specular reflection light of the sample.
4. The appearance of this instrument is novel, the structure is compact, and the professional circuit design effectively ensures the accuracy and stability of the measurement data.
5. Using high-pixel LCD module, Chinese display and prompt operation steps, display measurement and statistical results, friendly man-machine interface makes the instrument operation simple and convenient.
6. The instrument is equipped with standard RS232 interface, which can communicate with microcomputer software.
7. The instrument has power-off protection, and the calibration data will not be lost after power-off.
