Digital Cotton Flour Rice Whiteness Meter

Equipment description:

It is  in full accordance with international standards such as ISO 2469 requirements and our recent

release of the relevant national standards, industry standards to design formed. With 45 / O optical measurement system compared to similar devices, with lines from the sample surface caused by measuring reflection characteristics influence the direction of the advantages. Determination of the scattering coefficient of paper Zhang Duiguang and the optical absorption coefficient

Main function:

1, apparatus of the spectrum condition, by the strict integral filter match is made.
2, apparatus, controlled by micro-computing technology and automatic data processing, and can add the printer.
3, apparatus with a back-up electrical, data on the frequent power failure or shutdown will not be lost.
4, apparatus, switching power, high efficiency, small size, light weight, strong anti-interference, power supply for wide range of advantages.
5, instrument data can be set from the touch-type keyboard.
6, the instrument measurement data directly from the LED display shows measurement results.
7, measured ISO brightness (ie R457 Blu-ray brightness), fluorescent whitening on the samples can be measured by fluorescent emission of fluorescence brightness.
8, Determination of transparency (T) and the brightness of the object stimulus (V10).
9, determination of opacity (0).

To meet the standard:

1, in line with ISO2469 international standard d / o lighting observation geometry, the integrating sphere diameter of 150mm, test hole diameter 32mm, with shiny absorber to eliminate specular reflection light of the sample.
2, R457 optical system relative spectral power distribution: the main peak wavelength of 457 nm, half-wave width of 44nm, RY optical system consistent with CIE standard spectral power distribution of the Y10 stimulus conditions D65/100
3, apparatus, precision line JJG512-87 "White meter," a product of white meter's technical requirements.
4, consistent with JJG (light) 48-90 "reflection photometer," the requirements.

Applicable industry:

The instrument can be widely used in paper, cardboard, pulp, silk, textile, paint, cotton fiber, ceramic materials, porcelain clay, household chemicals, flour, starch, plastic raw materials and other objects of the brightness and other optical properties determined.
