Paper Dirtiness Tester

Product Introduction:

Paper dust meter is suitable for measuring the dust degree of paper or cardboard, books, toilet paper, tissue paper, etc.

The dust degree tester is lightweight in structure, convenient in experiment and equipped with different contrast pictures, and is widely used in major papermaking enterprises, quality inspection centers, press and publication centers and other units.

Test principle:

On each square meter of paper or cardboard, the dust degree is expressed by the number of dust with a certain area or by the equivalent area of dust on each square meter of paper or cardboard.

Product Advantages:

Measures Key Visual Quality Defect: Quantifies the amount of dust/dirt on paper and board surfaces, a direct indicator of visual quality.

Versatile Application: Suitable for testing various paper and board grades and products.

Standard Compliant: Designed to meet relevant national standards for paper and board dust determination.

Easy to Use: Lightweight structure and convenient design facilitate straightforward operation.

Provides Quantitative or Comparative Assessment: Enables assessment based on counting particles or comparing to standard charts, allowing for objective evaluation.

Used Across the Industry: Widely adopted in papermaking, printing, and quality inspection sectors.

Product Features:

Based on the provided information and typical paper dust testers operating on a visual comparison principle:

Illuminated viewing area with a specific irradiation Angle (60°) to highlight dust particles on the paper surface.

Table with an effective area of 0.0625 square meters for placing the paper or board sample.

The table can be rotated 360° for easy positioning and viewing of the sample.

Standard dust picture with ranges (0.05 - 5.0 mm²) to define different particle size categories for counting or comparison.

Standard dust comparison diagram with ranges (0.04 - 5.0 mm²) for visual comparison of dust particle sizes.

Light source (20W fluorescent lamp) to provide controlled illumination of the test area.

Lightweight structure for convenient handling and portability.

May include a counting grid or magnifier to aid in particle assessment.
