Automatic Intelligent Whiteness Tester
Product Introduction
Whiteness tester is a special instrument for measuring the whiteness of objects, which is widely used in the industries of paper making, printing, textile printing and dyeing, building materials, chemical industry, grain and salt making, and other production and commodity inspection departments that need to measure the whiteness of objects.
Application
Paper, cardboard, plastic, pulp; Salt, industrial salt, starch, calcium carbonate, talcum powder and other powders.
product function
ISO whiteness (R457 blue whiteness) and z whiteness (Rz) were measured.
Measure the fluorescence whitening degree produced by the emission of fluorescent substances (the sample contains fluorescence whitening).
Measure the whiteness of powder
Opacity OP (customized), light scattering coefficient S, light absorption coefficient A, transparency (customized) and ink absorption value were measured.
Measure the brightness stimulation value Y10, i.e. the diffuse reflection factor Ry of green light.
Determination of lead concentration (customized)
Product characteristics
Advanced circuit design effectively ensures the accuracy and stability of measurement data.
It can be measured many times and give the arithmetic mean of a series of measurement results.
Add data cache, which is convenient for users to back up, consult and compare historical data, and can store and remember reference sample information for up to ten times.
The instrument has power-off protection function, and calibration data will not be lost after power-off.
Adopt thermal printer core, no ink and ribbon, no noise at work, fast printing speed, etc.
This instrument is equipped with standard RS232 interface, which can communicate with microcomputer software (sold separately).
