Overview
The NBC-5635 whiteness meter is a special instrument for the measurement of LABThink whiteness on the surface of objects, and the measurement results are displayed through the LCD screen. The instrument is suitable for Spinning & Weaving, Printing and Dyeing, Chemical Fiber, Plastic, Ceramic Clay, Talc Powder, White Cement, Coating, paints, Pottery and porcelain, Enamel, paper, pulp and other industries to measure product whiteness.
Features
1. Instrument Appearance Novel Compact Structure, Professional Circuit Design Effectively Ensure Precision and Stability of Measurement Data
2. Instrument simulation D65 lighting body lighting
3. The instrument adopts d/o illumination to observe the geometric conditions, the diameter of the diffusing ball is 150mm, the diameter of the test hole is 19mm, and a light absorber is equipped to eliminate the influence of the specular reflection of the sample
4. The instrument has power-off protection function, and the calibrated data will not be lost after power-off
5. Can measure ISO whiteness, Lightness stimulation value, Opacity, transparency, light scattering coefficient and absorption coefficient, inks absorption value, reflected light density, lead core concentration and other parameters
Principle
The instrument uses d/o illumination to observe the geometric conditions, illuminates the sample through the diffuse ball and the test hole, eliminates the influence of the specular reflected light of the sample by using the light absorber, simulates the lighting conditions of the D65 illuminating body, and realizes the accurate measurement of the LABThink whiteness of the object surface.
