Brightness Meters

Our offered Brightness Meters are 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. DRK103A brightness meter also can test the papera s transparency, opacity, light scatting coefficient and light absorption coefficient.

Product features:-
* Test ISO whiteness (R457 whiteness) .It can also determine the fluorescent whitening degree of phosphor emission.
* Test of lightness tristimulus values (Y10), opacity and transparency. Test light scatting coefficient and light absorption coefficient.
* Simulate D56. Adopt CIE1964 supplement color system and CIE1976 (L * a * b *) color space color difference formula. Adopt d / o observing geometry lighting conditions. The diameter of diffusion ball is 150mm. The diameter of test hole is 30mm or 19mm. Eliminate the sample mirror reflected light by light absorbers.
* Fresh appearance and compact structure; Guarantee the accuracy and stability of measured data with advanced circuit design.
* LED display; Prompt operation steps with Chinese. Display statistical result. Friendly man-machine interface makes the operation simple and convenient.
* Instrument is equipped with a standard RS232 interface so it can cooperate with the microcomputer software to communicate.
* Instruments have a power-off protection; the calibration data is not lost when the power is cut off.
