ZB-D whiteness meter Introduction: The ZB-D whiteness meter is a special instrument for measuring the whiteness of an object. It is widely used in the measurement of whiteness of textile printing and dyeing, paint coating, chemical building materials, plastic products, cement, calcium carbonate powder, ceramics, enamel, porcelain clay, talcum powder, starch, flour, salt, detergent, cosmetics and other objects. Instrument function 1. Determine the ISO brightness (ISO brightness, R457 whiteness). For fluorescent whitening samples, the fluorescence whitening caused by the emission of fluorescent substances can also be determined. 2. Determine the lightness stimulus value. 3. Determine the opacity. 4. Determine transparency. 5. Determine the light scattering coefficient and absorption coefficient. 6. Determine the ink absorption value. 7. Determine the reflected light density. 8. Determine the lead core concentration. Features: 1. The appearance of the instrument is novel and compact, and the advanced circuit design effectively ensures the accuracy and stability of the measured data. 2. The instrument simulates D65 illuminator illumination. 3. The instrument uses d/o illumination to observe the geometric conditions. The diffusing ball has a diameter of 150 mm and a test hole diameter of 19 mm. It is provided with a light absorber to eliminate the influence of the specular reflected light of the sample. 4. The instrument has power-off protection, and the calibration data will not be lost after power-off. Technical Parameters: Power supply: AC220V±10% 50HZ Zero drift: ≤0.1 Indication drift: ≤0.1 Indication error: ≤0.5 Repeatability error: ≤0.1 Specular reflection error: ≤0.1 Specimen size: test plane not less than Φ30mm, thickness not exceeding 40 mm Instrument size (length * width * height) mm: 250 * 310 * 400 Net weight kg: 15
