Brightness Meter 1.Description: This brightness meter is mainly
used to measure the whiteness of paper, paperboard, paper pulps,
pulps of chemical fiber, cotton, chemical fiber, textile, plastic,
starch, salt, white cement, porcelain clay and talcum powder, etc.
It can also be used to measure the opacity and other optical
performance of thin pages. 1.1Measure the diffuse blue reflectance
factor (R**7), which is also called “blue brightness†or “ISO
brightnessâ€. 1.2Analyze whether the sample material contains
fluorescence brightener, and measure the fluorescence brightness
produced from fluorescence emission. ***** brightness degree.
1.3Measure the brightness stimulus value Y*0 of sample,
*****diffuse green reflectance factor Ry. 1.4Measure the
transparency, opacity, optical-absorption coefficient and
light-scattering coefficient of samples. 1.5Measure the ink
absorbency of paper and board. ***** technical features: 2.1
Measure and digital display the whiteness, fluorescence whiteness
and opacity (%), etc. 2.2 Zero drift: ≤0.1 2.3 Indication drift:
≤0.1 2.4 Indication error: ≤0.5 2.5 Repeatability error: ≤0.1
2.6 Error of specular reflection: ≤0.1 2.7 Sample size: testing
surface is not less than Φ*0mm, thickness of sample is not
exceeding *0mm 2.8 Power: ******0V, *0Hz, 0.3A 2.9 Working
environment: temperature is ***0℃, relative humidity is not
exceeding *5%. 2.*0 Size and gross weight: **0***0***0mm, *0Kg
