Overview
ERICHSEN Erichsen 232/100μm Grindometer is a specialized instrument for the measurement of the fineness of coatings. Made of hardened steel with two precisely machined notches, Measurement range 0 to 100μm, stainless steel scraper, Net weight 0.8kg.
Features
1. Made of hardened steel, special treatment to ensure dimensional Stability
2. double-channel design, equipped with two precision-machined trough
3. Provide two units of μm and Hegman scale
4. Equipped with stainless steel scraper, size 125mm
5. Measurement range 0~ 100μm, Graduation 10μm
Principle
The fineness meter scrapes the test coating into a V shape to visually find the position where the particle size of the coating is greater than the height of the V-shaped groove. The depth of the groove is read at the boundary position between the smooth and uneven surface of the sample, which is the fineness value of the paint.
Steps
1. Pour enough test material into the deep end of the trough, being careful not to bubble
2. Handheld scraper, perpendicular to Fineness Gauge and groove, smoothly scrape the material to the narrower end of the groove, Travel takes 1-2 seconds to complete
3. Evaluate within 3 seconds after scraping, with a line of sight perpendicular to the groove and a viewing angle of 20-30 degrees
4. Find the location where the particles gather or scratch, and the groove depth corresponding to this location is the fineness of the test material
Notice
• The fineness meter should be cleaned with solvent immediately after use
Do not use sharp objects to remove residual paints
• Apply minimal force when operating
• The straight edge of the scraper will be subject to continuous abrasion and needs to be checked regularly
• Place the scraper on the horizontal plane during inspection and check according to the principle of light transmission
