Overview
The ERICHSEN Erichsen 232/50μm Grindometer is a professional instrument for measuring the fineness of coatings. Made of hardened steel, it features two precisely machined grooves with a Measurement range of 0 to 50μm and a stainless steel scraper for fast and accurate assessment of coating particle fineness.
Features
1. Adopt special treatment hardened steel material, Good Size Stability
2. Double-channel design, providing two precision-machined trough-shaped grooves
3. Clear scale, marked with μm and Hegman scale units
4. Equipped with stainless steel scraper, easy to operate
5. Graduation is 5μm, Measurement accuracy is high
Principle
Grindometer scrapes the test paint into a V shape, and the operator visually observes the position where the particle size of the paint is greater than the height of the V-shaped groove. The depth of the groove at this position is read at the boundary position between the smooth and uneven surface of the sample, which is the value of the fineness of the paint.
Steps
1. Pour enough test material into the deep end of the trough to avoid bubbles
2. The hand-held scraper is perpendicular to the Fineness Gauge and the groove, and the material is smoothly scraped to the narrower end of the groove. Travel takes 1-2 seconds to complete
3. Evaluate within 3 seconds after scraping
4. The line of sight is perpendicular to the groove, and the viewing angle is 20-30 degrees
5. Find the location where the particles gather or scratch, and read the corresponding groove depth to be the fineness value
Notice
• Wash with solvent immediately after use
• Do not use sharp objects to remove residual paints
• Apply minimal force when operating
• Regularly check the straight edge abrasion of the scraper
• When checking the scraper, place the scraper on the horizontal plane and check according to the principle of light transmission
