Introduction ZB-B tester is used for the measurement of whiteness, it is widely used in papermaking, textile, printing and dyeing, plastic, ceramic, enamel, paint, food, building materials, chemical, salt and other needs of special white production and inspection department.
Features Determination of whiteness of ISO (ISO Brightness, R457 whiteness of fluorescent brightener), the sample can be determined, the fluorescent substance emission fluorescent whitening degree. Determination of lightness of stimulus value Y10. Determination of opacity (Opacity). Determination of transparency. Determination of light scattering coefficient and absorption coefficient. Determination of ink absorption value.
Technical parameters Zero drift: 0.1 or less; Drift value: 0.1 or less; of error of 0.5 or less; Repeatability error: 0.1 or less; Specular reflection error: 0.1 or less; ZB - B whiteness meter environmental requirements Temperature: 15 ~ 40 ℃ Relative humidity: less than 85% Power supply: 220 v, 50 hz
