BGD 584 ISO 2471 Multi-function Whiteness Meter Full Touch Screen
Operation Digital Brightness Tester
1.Description
BGD 584 Multi-function Whiteness Meter adopts touch screen display and operation, integrates light,
mechatronics and micro-computer measurement and control technology,
and has the function of test data statistics processing, which can
quickly and accurately mea sure the whiteness (brightness) of various objects. It can be
widely used in the determination of whiteness of pigments, fillers
or other powders in coatings, as well as in papermaking, textile,
printing and dyeing, plastics, ceramics, enamel, grain, building
materials and other industries. The instrument can measure not only
ISO brightness (R457 whiteness), but also the fluorescent whiteness
of fluorescent materials, and also the brightness stimulation value
Y10, transparency, opacity, light scattering coefficient and
absorption coefficient of coating, paper and other thin page
materials.
BGD 584 complies with CIE 15 and CIE S 005 <standard illuminants and geometric conditions>, simulating D65 illuminant lighting, adopting d / 0 lighting observation geometry conditions , diffusion
ball diameter isφ150 mm, with two test hole diameter, φ 30 mm and φ
19 mm, equipped with light absorber, eliminating the influence of
specular reflection light (SCE). The peak wavelength of spectral
power distribution of R457 whiteness optical system is 457 nm, half
height and width is 44 nm.
2.Features
◆ Come with powder sampler for powder measurement
◆ Come with thermal printer
◆ Can measure continuously sample many times and calculate
automatically the arithmetic mean value.
◆ With power-off protection, zero adjustment, alignment, standard
value and other data, even if the power is lost for a long time,
the data will not be lost.
