Overview
PUYUN PY-E625 Dust meter is an instrument specially designed to measure the dust degree of paper and Cardboard. It is suitable for the determination of fiber bundles and other impurities (ie dust) that can be seen at every angle of the paper surface. It is suitable for food parchment, translucent paper, food Encasement Cardboard and other materials in the QS certification of paper Encasement.
Features
1. Using a 20W fluorescent light source, the illumination angle is 60 °.
The effective area of the workbench is 0.0625 square meters, and it can be swirled/spun at 360 °, which is convenient for multi-angle observation.
3. Equipped with a standard dust map, covering an area from 0.05mm ² to 5.0mm ².
4. Dimensions of the instrument are 750 * 350 * 500mm and the weight is about 22kg.
Principle
The instrument illuminates the surface of the sample with a fluorescent light source at a specific angle and intensity according to the standard method, so that dust (including fiber bundles and other impurities) that are different from the paper surface appear. The operator counts and evaluates the area of dust in the effective area by observing and comparing the standard dust map to determine the dust level of paper or Cardboard.
Applications
Food Parchment, Translucent Paper, Food Encasement Cardboard
Steps
1. Prepare paper or Cardboard samples to be tested.
2. Place the sample on the instrument bench.
3. Turn on the 20W fluorescent light source.
4. Swirl/spin table to observe the sample surface from different angles.
5. Identify and count fiber bundles and impurities (dust) that are different from the paper Color.
6. Compare the observed dust with a standard dust map to evaluate its area.
7. Record the measurement results.
Notice
• Please ensure that the instrument is placed smoothly before use.
• Please pay attention to the light source when operating and avoid direct gaze.
• Keep worktops and standard dust charts clean.
• Please measure and interpret the results according to the GB/T1541-2013 standard.
• Please turn off the power when the instrument is not in use.
