Introduction: HH-BD48B whiteness tester (also known as whiteness meter, whiteness meter) is mainly measuring paper and paperboard, pulp and chemical fiber pulp, cotton and chemical fiber, textiles, plastics, ceramics, pond porcelain, starch, salt, white cement , Porcelain clay, talc and other objects of whiteness. Optical properties such as the opacity of sheet materials can also be measured. The instrument complies with GB3978-83; standard lighting and lighting observation conditions. D65 lighting simulation lighting. Using d / o lighting observation geometry, the diffuser diameter is 150mm and the diameter of the test hole is 30mm. A light absorber is provided to eliminate the influence of specular reflection on the sample. The peak wavelength of spectral power distribution of R457 whiteness optical system is 457nm and the FWHM is 44 nm. The Y10 optical system complies with GB3979-83. The object color measurement method. Determination and digital display whiteness, fluorescence (whitening) whiteness, opacity (%) and so on. Features: 1, the instrument uses light, machine, electric integration design, microcomputer monitoring and control technology, compact structure, elegant appearance, easy maintenance. 2, with test data statistical analysis and processing functions. 3, a wide range of tests, can test a variety of objects whiteness (brightness), opacity, transparency, light scattering coefficient and optical absorption coefficient. 4, Chinese graphical menu display interface, easy to operate. Technical Parameters: 1, zero drift: ≤ 0.1 2, showing the value of drift: ≤ 0.1 3, indicating the error: ≤ 0.5 4, Repeatability error: ≤0.1 5, mirror reflection error: ≤ 0.1 6, the sample size: the test plane is not less than Φ30mm, the sample thickness does not exceed 40mm 7, Power: AC220V 50Hz 0.2A 8, the working environment: temperature 0 ℃ ~ 40 ℃, relative humidity does not exceed 85% 9, Dimensions: 365mm × 260mm × 425 mm 10, weight: about 11kg
