1 INTRODUCTION
The Elcometer 124 Foil Thickness Gauge measures the thickness of sheet material, foils and the size of
small items.
It is mainly used to measure Elcometer 122 Testex Tape, which records surface profiles.
1.1 STANDARDS
Together, your Elcometer 124 Foil Thickness Gauge and Elcometer 122 Testex Tape can be used in
accordance with the following National and International Standards: ASTM D4417-C, BS ISO 8503-5,
NACE RP 0287, US Navy NSI 009-32, US Navy PP1 63101-000.

2 USING THE FOIL THICKNESS GAUGE
1. Open the jaws by the lever at the top of the dial
2. Insert the sample between the anvils. Gently release the lever.
3. The long needle indicates small changes in thickness, the short needle shows how many complete
turns made by the long needle.
To set Zero, check that the measuring faces of the anvils are clean. Release the knurled screw on the top
left of the dial and turn the scale until ‘0’ lines up with the end of the long needle. The short needle should
be close to ‘0’.
To calculate the thickness, first look at the short needle to see how many revolutions have been counted
on the small scale. Multiply this number by the full-scale value and add on the long needle reading to obtain
the total thickness.
The two black markers on the outer edge of the dial can be positioned to indicate the upper and lower
specification limits.

3 USING THE ELCOMETER 124 WITH ELCOMETER 122 TESTEX TAPE
Elcometer 122 Testex Tape comprises two layers of plastic; a soft layer which carries an impression of the
rough surface and a hard layer 50 microns (2 mil) thick which acts as a substrate for the soft layer. Only the
thickness of the soft layer needs to be recorded.
The Elcometer 124 can be set to subtract automatically the thickness of the hard layer from the total
thickness of the tape:
• Ensure the faces of the anvil are clean.
• Loosen the knurled screw near the top of the dial and rotate the large scale clockwise until the long
needle points to 150 microns or 8 mil.
• Tighten the knurled screw.
Readings of Elcometer 122 Testex Tape samples will now be shown directly by the long needle, effectively
by having 50 microns (2 mil) subtracted from the total thickness.
4 MAINTENANCE
Elcometer products are designed to give many years reliable service under normal operating and storage
conditions.
Ensure the anvils are kept clean.
