Product Description

ST-48B Brightness Meter is a special instrument for measuring the whiteness of objects. It is widely used in paper making, 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.

Brightness Meter Application

For paper, cardboard, plastic, pulp, salt, industrial salt, starch, calcium carbonate, talcum powder and other materials whiteness index measurement.

●  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)

Brightness Meter Advantages

●  The advanced circuit design effectively ensures the accuracy and stability of the measurement data

● With power-off protection function, calibration data will not be lost after power-off

● Standard RS232 interface, communication with microcomputer software (optional)
