Features
The Fineness of Grind Gage is a flat steel block in the surface of which are two flat-bottomed grooves varying uniformly in depth from a maximum at one end of the block to zero near the other end. Groove depth is graduated on the block according to one or more scales used for measuring particle size.
The Hegman scale or National Standard scale may be abbreviated "NS" on the gage. The scale ranges from 0 to 8 with numbers increasing as the particle size decreases.
- 0 Hegman = 4 mil/100 micron particle size
- 4 Hegman = 2 mil/50 micron particle size
- 8 Hegman = 0 mil/0 micron particle size
- Grind blocks made of high quality, corrosion resistant stainless steel for extended use
- Dual channel designs
- Groove depth is graduated on the block showing mils and Hegman scales
- Grind gages are available in different path size lenghts

Procedure
Place a slight excess of sample in the deep end of the groove and, with the straight-edge scraper provided, draw the sample toward the shallow end of the groove. Ratings are in terms of the point on the scale where the oversize particles, or traces made by them, first appear in substantial concentration.
