Whiteness Meter

Optical, mechanical and electrical integrated design, microcomputer measurement and control technology, compact structure, beautiful appearance, easy maintenance. The instrument is mainly used for the measurement of paper, Cardboard, Pulp, Spinning & weaving products, Plastic, Ceramics and other materials whiteness, and can also measure the opacity of thin sheet materials and other Optical Properties.

Measure the blue light diffuse reflection factor (R457) of the sample, blue light whiteness or ISO whiteness, Precision ≤ 0.5%, resolution 0.1/0, Repeatability ≤ 0.02%, mirror reflection error ≤ 0.1%

The test plane is ≥ 30mm, the thickness is less than or equal to 40mm, the diameter of the diffusing ball is 150mm, and the diameter of the test hole is 19mm. A light absorber is provided to eliminate the influence of the specular reflection of the sample.

Used to test the whiteness value of paper, Spinning & weaving, plastic, paints, etc., using 30W halogen tungsten lamp, WSB digital Whiteness Meter indication interval is 0-100, error of indication is +/- 2.5.

With ISO whiteness, fluorescence whiteness and other test functions, support opacity, light scattering coefficient and other data analytics. Data cache and historical data management functions to ensure the stability and accuracy of measurement results. Built-in RS232 interface

Automatic one-click measurement, measuring ISO whiteness, CIE whiteness, fluorescent whiteness and other indicators, high-pixel LCD display, easy to operate, built-in thermal printer, no inks, fast printing.

Error of indication ≤ 0.5, repeability ≤ 0.02, supports accurate measurement of ISO whiteness, fluorescence whiteness, transparency and other parameters, built-in thermal printer provides fast and noiseless printouts, supports RS232 interface
