Product details
HP-BD48A type color determination instrument (also known as the white color determination instrument, whiteness instrument, whiteness colorimeter, colorimeter, whiteness and color meter, color meter) are widely used in papermaking, printing, textile printing and dyeing, ceramics, building materials, chemical, food, salt and other industries, mainly for the determination of the object of whiteness, yellow, color, can also determine the tissue paper opacity, transparency, light scattering coefficient, light absorption coefficient and ink absorption value.
This instrument can be used for the determination of CIE (1982) whiteness (Gantz visual brightness) and color value Tw10 W10. ISO whiteness (R457 white degree) and Z white degree (Rz) were measured. For the fluorescent whitening samples, the fluorescent whitening degree can be determined. Determination of whiteness of building materials and non metallic minerals WJ. Can also be measured Hunter whiteness WH.
Product features
1, determine the object's color, report diffuse reflectance factor Rx, ry and RZ, stimulate value X10, Y10, Z10, chromaticity coordinates of X10, gives and brightness (L *) and color a *, b *, chroma C*ab, hue angle h*ab, dominant wavelength lambda D, excitation purity of PE, color difference Delta E*ab, lightness difference delta L, chroma difference Delta C*ab and color tone difference Delta H*ab and Hunter L, a, B.
2, the instrument has increased the function of measuring lead core concentration.
3, the instrument added to the printer and the use of imported thermal printer core, without the use of ink and ribbon, work without noise, fast printing speed and so on.
4, the instrument is equipped with a standard RS232 interface, can be combined with the computer software for communication.
5, the determination of yellow YI, opacity OP, light scattering coefficient S, light absorption coefficient A, transparency, ink absorption value.
6, the reference sample can be kind, but also for the data. The instrument can store up to ten reference samples.
7, the instrument has a memory function. Even if the long-term shutdown loss of power, memory zero, calibration, standard sample and reference value and other useful information will not be lost.
8, measurement of reflected light density Dy, Dz (lead core concentration).
