Paper and Board R457 Brightness Meter

ZYWM-48BN 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

● Advanced circuit design to ensure the accuracy and stability of measurement data

● Can be measured multiple times and gives the arithmetic mean of a series of measurements

● Increase data cache, convenient for users to backup, review, compare historical data, can store up to ten reference information

● The instrument has a power-off protection function, and the calibration data will not be lost after power-off.

● Thermal printer core, no need to use ink and ribbon, no noise when working, fast printing speed, etc.

● This instrument is equipped with standard RS232 interface, which can be used with PC software for communication (optional)
