Description

Brightness Meter is a special instrument for measuring the whiteness of objects. It is widely used in papermaking, printing, textile printing and dyeing, building materials, chemical, food, salt and other industries and other production and commodity inspection departments that need to measure the whiteness of objects.

Application Function

Measure D65 brightness (R457 blue light whiteness)

Measure the degree of fluorescent whitening produced by the emission of fluorescent substances (the sample contains fluorescent whitening agent)

Measure opacity OP (customized), light scattering coefficient S, light absorption coefficient A, transparency (customized), ink absorption value

Measure the brightness stimulus value Y10, which is the green diffuse reflection factor Ry

Measure optical density-lead core concentration (customized small caliber)

Application Range

Paper, cardboard, plastic, pulp, salt, industrial salt; Starch, calcium carbonate, talcum powder and other powders.

Product Features

Advanced circuit design effectively guarantees the accuracy and stability of the measurement data
The instrument has a power-off protection function, and the calibration data will not be lost after power-off
This instrument is equipped with standard RS232 interface, which can be used with PC software for communication (optional)
