Paper whiteness tester

• 

Introduction:

Paper whiteness tester is suitable for the whiteness measurement of non-color surface flat objects or powders, and can accurately measure the whiteness value consistent with the visual sensitivity. Widely used in paper and cardboard, textile printing and dyeing, paint, chemical building materials, plastic products, cement, calcium carbonate powder, ceramics, enamel, China clay, talc powder, starch, flour, salt, detergent, cosmetics and other objects whiteness measurement.

Standard:

GB7973. GB7974. ISO 2470. GB 13025.2. GB 8940.2. GB 1840. GB 2913. GB 1543-88. ISO 2471. GB10339-89. GB5950

Application:

Paper: Test the fluorescent whiteness of paper

Aluminum plating: Test the transparency, opacity and whiteness of aluminum foil

Plastics: Test the whiteness of plastics and powders

Paint: Test the whiteness and absorption value of paints, coatings, inks, etc

Advantages:

Quantifies Whiteness Objectively: Provides a numerical value for whiteness, eliminating subjective visual assessment.

Wide Range of Applications: Suitable for testing diverse materials, including paper, textiles, plastics, and powders, across multiple industries.

Consistent with Visual Perception: Designed to measure whiteness in a way that correlates well with how humans perceive it, including accounting for fluorescence.

Standard Compliant: Adheres to various national and international standards for whiteness, brightness, and opacity measurement.

Measures Related Optical Properties: Capable of evaluating transparency, opacity, and absorption value in addition to whiteness for certain materials.

Facilitates Quality Control and Research: Enables manufacturers to set specifications, monitor production consistency, and support research and development of new materials.

User-Friendly Operation: Typically features an intuitive interface for ease of use.
