Brightness Meter 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.
Product Introduction
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 Range
Brightness Meter is suit for Paper, cardboard, plastic, pulp, salt, industrial salt； Starch, calcium carbonate, talcum powder and other powders.
Product 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)
Prouduct Feature
● Advanced circuit design effectively guarantees the accuracy and stability of the measurement data
● Brightness Meter 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)
