Brightness Meter

TTM-48B 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.

Model

TTM-48B

Application Range

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

Application Function

  1. Measure ISO whiteness (R457 blue whiteness) and Z whiteness (Rz)
  2. Measure the fluorescence whitening caused by the emission of fluorescent substances (the sample contains fluorescent whitening)
  3. Measure the whiteness of the powder
  4. Measuring opacity OP, light scattering coefficient S, light absorption coefficient A, transparency, ink absorption value
  5. Measuring the brightness stimulus value Y10, that is, the green light diffuse reflection factor Ry

Product Features

  • 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.
