HST Laboratory ISO R457 Fabric Meter Intelligent Whiteness Analyzer
1.Equipment description:
Paper Brightness Whiteness Meter 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 and the optical absorption coefficient of pape.
2.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).
3.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.
4.Applicable industry:
The Brightness Whiteness Meter 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.
