1 OVERVIEW

Fineness of Grind Gauges are used to determine particle size and
fineness of grind. They are suitable for measurement of many
materials, including paints, pigments, inks, printing inks, coatings,
chocolates and other similar products. They may also be used to
indicate the presence of undesirable large particles in these materials.
A scraper is used to pull the material along a sloping groove machined
into the top surface of the gauge and the fineness of grind is read
directly from a scale engraved into the gauge.
Elcometer 2020: This model has two grooves and graduations
marked in microns or mils, NS or H (Hegman) and PCU (Paint Club
Units) on the top of the gauge.
Elcometer 2050: This model has a single groove and graduations
marked in microns or mils on the top of the gauge.
Elcometer 2070: This model has two grooves and graduations marked
in microns or mils and NPIRI (National Printing Ink Research Institute)
on the top of the gauge.

3 TEST PROCEDURE

Before you start:

2 Perform a preliminary test to determine the size of gauge most
suitable for the fineness of grind characteristics of the material
being measured.
