How to measure dispersion using Elcometer Fineness of Grind Gauges

 

Whether you’re developing coatings, inks, or cosmetics in a laboratory or testing during the production process, 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.

 

Elcometer’s fineness of grind gauges consist of a stainless steel block with a precision ground scraper. Each block has either one or two channels, precision ground in a uniformly increasing depth from zero at one end, to a specified depth at the other, identified by the scale on the gauge.

 

This single channel precision grind gauge is used to determine particle size and fineness of grind for many materials including paints, pigments, inks, coatings, chocolates and other similar products.

 

Dual channel gauges also allow you to test different material formulations side-by-side, so you can instantly compare the results.
