TESTING & MEASUREMENT
Elcometer 456 Scanning Probes
speed up coating thickness testing
Elcometer offer three scanning probe
options for the very popular Elcometer 456
Coating Thickness Gauge. The Elcometer
456 Digital Coating Thickness Gauge
sets high standards for dry fi lm thickness
measurement, providing fast, reliable and
accurate readings, helping to ensure
that the coating process is in control
and the specifi cation is being met to aid
in the achievement of the desired coating
service life.
interchangeable probes and output to ElcoMaster ® software,
makes the Elcometer 456 very powerful.
Measurement accuracy capability to ±1% on smooth, rough, thin
and curved surfaces the Elcometer 456 gives you repeatable and
reproducible results. It comes with a 2-year gauge warranty.
Incredibly fast measuring speed of more than 70 readings per
minute (140+ readings per minute with the Ultra/Scan probes)
– the Elcometer 456 is more than 40% faster than other gauges.
These scanning probes are called Ultra/Scan probes and are
available for measurement of coating thickness on either ferrous
metals (F) or non-ferrous metals (NF). The probes are supplied as F
only or dual FNF options. For ferrous substrates there are two scale
ranges available, F1 for thicknesses in the range 0 – 1,500 µm and
F2 for thicknesses in the range 0 to 5,000 µm. The FNF scale range
is 0 to 1,500 µm, the non-ferrous (NF) principle can be used for
measuring coatings on non-ferrous metals.
Ferrous (F) probes are suitable for measurement of non-magnetic
coatings, such as paints, varnishes, plastics, rubbers, etc. on ferro-
magnetic substrates e.g. steel, magnetic stainless steel, cast iron, etc.
Non-ferrous (NF) probes are suitable for non-conductive coatings on
non-ferrous metals, such as aluminium, aluminium alloys, non-
magnetic stainless steels, copper, zinc, etc.
Dual Ferrous/Non-ferrous (FNF) probes combine these two
measurement capabilities into a single dual purpose probe. Gauges
used with dual FNF probes can be set up to automatically recognise
the type of substrate or can be set to measure on a particular type of
substrate.
The Elcometer 456
Coating Thickness Gauge
Available in a range of models with different measurement and
software options for measuring dry film thickness on ferrous &
non-ferrous metal substrates, the Elcometer 456 is powerful,
rugged and easy to use.
Key features include:
2.4” colour display, clear menu structure and large buttons,
make the Elcometer 456 very easy to use.
Impact resistant and sealed against dust and water, the Elcometer
456 is extremely rugged and is ideal for use in all environments.
Memory capacity of up to 150,000 readings in up to 2,500
individual batches with alpha-numeric identification,

The Elcometer 456 is supplied complete with the ElcoMaster ®
software which provides simple and efficient data management for a
range of coating inspection instruments. ElcoMaster ® can also be
downloaded free of charge from the Elcometer website.
The Ultra/Scan Probes come fitted with a ‘snap on’ replaceable
plastic end cap so that the sliding action required to carry out a scan
of the whole coated surface does not cause any wear to the probe tip.
This is crucial to maintaining the accuracy of the probe over its
