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.

User Guide

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

www.elcometer.com

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

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

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)

www.elcometer.com en-4

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

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.

Description Part Number

Replacement Scraper for Elcometer 2050 KT002030N001

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.
