Introduction
Brightness Meter is widely applied in papermaking, fabric, printing, plastic, ceramic and porcelain enamel, construction material, chemical industry, salt making and other testing department that need to test whiteness. DRK**3A brightness meter also can test the paper’s transparency, opacity, light scatting coefficient and light absorption coefficient.

Characteristics
1Test ISO whiteness (R**7 whiteness) .It can also determine the fluorescent whitening degree of phosphor emission.
2 Test of lightness tristimulus values (Y*0), opacity and transparency. Test light scatting coefficient and light absorption coefficient.
3 Simulate D*6. Adopt CIE***4 supplement color system and CIE***6 (L * a * b *) color space color difference formula. Adopt d / o observing geometry lighting conditions. The diameter of diffusion ball is **0mm. The diameter of test hole is *0mm or *9mm. Eliminate the sample mirror reflected light by light absorbers.
4 Fresh appearance and compact structure; Guarantee the accuracy and stability of measured data with advanced circuit design.
5 LED display; Prompt operation steps with Chinese. Display statistical result. Friendly man-machine interface makes the operation simple and convenient.
6 Instrument is equipped with a standard RS**2 interface so it can cooperate with the microcomputer software to communicate.
7 Instruments have a power-off protection; the calibration data is not lost when the power is cut off.

Application
Brightness Meter is widely applied in papermaking, fabric, printing, plastic, ceramic and porcelain enamel, construction material, chemical industry, salt making and other testing department that need to test whiteness. PN**8B brightness meter also can test the paper’s transparency, opacity, light scatting coefficient and light absorption coefficient.

Standards

In accordance with GB******3: Standard lighting and lighting and observation conditions.
Simulate D*6. The diffuse diameter is **0mm and test whole diameter is *0mm or *9mm. It uses light absorber to eliminate the influence caused by the specimen’s mirror reflecting light.
R**7 whiteness optical spectral power distribution system in the peak wavelength **7nm, FWHM *4nm, RY*0 optical system in line with the GB******3: object color measurement.
GB******7: Pulp, paper and paperboard diffuse reflectance factor assay (d/o method).
GB******7: paper and paperboard whiteness assay (d/o method).
