Elcometer 2020 Fineness of Grind Gauges

The Elcometer Fineness of Grind Gauges are used to determine the particle size and fineness of grind of many materials including paints, pigments, inks, coatings, chocolates and other similar products. 

These two channel gauges, are made of hardened stainless steel and have two grooves with a graded slope (dependent on the model chosen). 

Graduated in microns, mils, NS (Hegman) or PCU (North), the gauges have a accuracy of ±3μm (0.12mil) or ±5% whichever is the greater.  The groove width for all models is 12mm (0.47”) with a groove length of 127mm (5.0”).

The material is placed on the deepest part of the groove and, using the scraper provided, drawn up the slope - the particle size is indicated where the material stops.

How to measure dispersion using Elcometer Fineness of Grind Gauges

Measuring the particle size of the material (also known as dispersion) is an essential part of ensuring reliable and repeatable formulations. Typically, to measure dispersion, fineness of grind gauges are used.
