LCD Electronic Digital Plastic Film Paper Brightness Whiteness Opacity Tester 0-199
Electronic Digital Plastic Film Paper Brightness Whiteness Opacity Tester is mainly applied to measure the non-colored surface of a flat object or white powder, can be accurately drawn with the visual. It is in full accordance with international standards such as ISO 2469 requirements and 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 whiteness and the optical absorption coefficient.
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
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.
Electronic Digital Plastic Film Paper Brightness Whiteness Opacity Tester 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.
