Overview
The QXD-25 double-channel Fineness Gauge is an instrument for the measurement of particle size distribution or particle size of substances such as coatings, inks, pigments, cosmetics, etc. It evaluates the particle size and dispersion of the sample by scraping the sample and observing the film thickness or particle distribution of the residual material. The product is made of wear-resistant stainless steel with a range of 0~ 25μm and a groove size of 140 × 12.5mm. It meets relevant standards.
Features
1. Made of wear-resistant stainless steel, with strong durability.
2. Double scraping groove design, can be compared or repeability test.
3. The range is 0~ 25 μm, Graduation fine to 0.7 μm.
The groove size is 140 x 12.5mm, which meets the standard specifications.
Principle
The Working Principle of this Fineness Meter is to Spreader the sample to be tested on a flat substrate, and then use a scraper to scrape the material flat. The particle size and dispersion uniformity of the sample are evaluated by observing the film thickness or particle distribution of the residual material on the scraper.
Applications
Paint, paste, plastic, inks, paper
Standards
Meet the standard
Steps
1. Spreader the sample to be tested on a flat substrate of Fineness Gauge.
2. Use a scraper to flatten the sample, ensuring that the entire trench area is covered.
3. Observe the film thickness or particle distribution of the residual material on the scraper.
4. Evaluate the particle size of the sample according to scale or standard comparison.
Notice
• This product is suitable for the determination of highly corrosive materials. Please confirm the sample compatibility before use.
• After use, the scraper and groove should be cleaned in time to avoid sample residue affecting the subsequent measurement accuracy.
• When operating, ensure that the scraper scrapes smoothly and evenly across the sample surface.
• Please select the appropriate measurement range according to the product specifications.
