1 OVERVIEW
Elcometer 2050: This model has a single groove and graduations
marked in microns or mils on the top of the gauge.
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.
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.
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.

1 Ensure the gauge and scraper are clean (see Section 3.3
‘Cleaning After Test’ on page en-4).
2 Perform a preliminary test to determine the size of gauge most
suitable for the fineness of grind characteristics of the material
being measured.
Before you start:
3 TEST PROCEDURE

R
en-3
3 TEST PROCEDURE (continued)
1 Place the gauge on a flat, horizontal and non-slip surface, with
the zero mark on the scale closest to the user.
2 Place a suitable amount of the material in the deep end of each
groove.
4 Pull the scraper along the length of the gauge at a constant
speed . Stop at a point beyond the zero depth. This operation
a
should take approximately 1 to 2 seconds.
3 Place the scraper on the surface of the gauge behind the
material. Use both hands to hold the scraper.
b A recommended method is to record 2 values: Position one - where there are 4 scratches, and Position
two - where there are 10 scratches.
a Apply sufficient downward pressure to clean excess material from the edges of the gauge. Avoid the
formation of air bubbles.
7 Use a suitable solvent to clean the gauge and scraper.
8 Perform two more tests and calculate the average value of the
results. The average value is the fineness of grind of the
material.
Elcometer 2070: Find the first position in the
material where a given number of scratches
b
can be seen. Read the scale and record this
value.
6 Elcometer 2020 and 2050: Find a band
across the groove(s) 3mm (1/8”) wide which
contains 5 to 10 particles of the material.
Read the position of the upper limit of this
band on the scale and record this value.
5 View the drawn out material within the next 3 seconds. This avoids
inaccurate testing due to evaporation of the material. The material
should be viewed at right angles to the length of the groove and at
an angle of 20° to 30° with the surface of the gauge.
3 mm (1/8")

3 TEST PROCEDURE (continued)

R
Store the gauge and scraper in the case provide when not in use.
Always clean the gauge after each test using a suitable solvent. After
c
cleaning and to protect against rust , ensure that all materials are
removed and that the gauge is dry. Apply a thin layer of oil to the
surface of the gauge and the scraper before storage.
3.3 CLEANING AFTER TEST
DO NOT use very aggressive solvents or wire brushes, metal
scrapers, metal files, or other metallic tools for cleaning.
c Rust can appear on the gauge when it is only used occasionally and when it has been handled by users
with sweaty hands.

Regularly inspect the gauge and scraper for signs of wear or damage.
2 Shine a bright light towards the back of the
scraper. Rock the scraper backwards and
forwards and inspect the contact edge for
any light coming through between the
scraper and gauge.
To inspect the scraper:
1 Place the edge of the scraper on a
reference plane (the smooth, level face of
the gauge is a good alternative).
If light is visible, the scraper is not suitable for use and should be
replaced.
