YQ-Z-48B whiteness meter Introduction: The YQ-Z-48B whiteness meter is used to determine the whiteness of an object. It is widely used in paper, textile, printing and dyeing, plastics, ceramics, enamel, grain, building materials, paints, chemicals, salt and other production and commodity inspection departments that need to measure the whiteness of objects. The instrument can also measure ISO brightness (ISO brightness, R457 whiteness). For fluorescent whitening samples, the fluorescence whitening of the fluorescent material can be measured, and the transparency of paper and other thin materials can be determined. Transparency, light scattering coefficient and absorption coefficient. Features: 1. Determination of ISO brightness (ISO Brightness, R457 whiteness). For fluorescent whitening samples, the fluorescence whitening degree produced by the emission of fluorescent substances can also be determined. 2. Determine the brightness stimulus value Y10; 3. Determine opacity (Opacity); 4. Measuring transparency; 5. Measuring the light scattering coefficient and the absorption coefficient; 6, can be measured multiple times and give the arithmetic mean of a series of measurement results; 7, with power-off protection, zero adjustment, alignment and standard value and other data, even if the power is lost for a long time, the protection data is not lost. Technical Parameters: 1, zero drift: ≤ 0.1%; 2. Indication drift: ≤0.1%; 3. Indication error: ≤0.5%; 4, repeatability error: ≤ 0.1%; 5, specular reflection error: ≤ 0.1%; 6, sample size: test plane ≥ ¢ 30mm, thickness ≤ 40mm; 7, power: 220V ± 10%, 50Hz; 8, working environment: temperature 0 ~ 40 ° C, relative humidity does not exceed 85%; 9. Dimensions (length × width × height), mm: 365 × 260 × 425; 10. Instrument quality: about 11kg.
