Scraper Method Particle Size Analyzer

The drawdown gauge utilizes a graduated wedge-shaped groove and a scraper to spread the sample into a film of decreasing thickness. Under specific lighting conditions, the positions where particles become visible are observed, and the corresponding graduations are used to read the particle size. It is employed in industries such as coatings and inks for rapid detection of the particle size distribution of pigments and fillers.
Selection
When selecting a drawdown bar applicator, it is essential to ensure that the measurement range covers the particle size of the sample, and the groove depth specifications comply with industry standards. Pay attention to the wear resistance of the bar material and the clarity of the scale to ensure ease of operation. Verify the repeatability of the instrument and ensure it meets the requirements of routine laboratory testing environments.
