Fineness of Grind Gauges & Physical Test Equipment
The fineness of grind gauge is an easy to use, relatively inexpensive production and quality control instrument that enables the manufacturer to check for unwanted agglomerates as well as particles that are too large. Fineness of grind gages and scrapers are consumable products and need to be refinished or replaced when they show visible damage to the gauging surface or readings become suspect.
Hegman, micron, mils and NPIRI are common scales on fineness of grind gauges, wedge plates and printing plates. P.C. scale or the N.S. scale (In 1968 PG&T changed N.S. to H for Hegman) are sometimes used on older gauges.
