Probes - Elcometer 456 3 Operating Instructions Manual

7 PROBES

An extensive range of probes is available for the
3
Elcometer 456 Coating Thickness Gauge. Probes
for ferrous (F), non-ferrous
ferrous/non-ferrous (FNF) operation are available
as either integral (built-in) or separate options.
Separate probes are fully interchangeable and are
available in standard, PINIP™ and miniature
formats.
PINIP™ format (Plug-In Integral Probe) is an
integral style probe which plugs in to a separate
gauge. This provides all the benefits of an integral
gauge and the flexibility of a separate gauge in a
single unit.
Miniature separate probes permit measurements
where space is restricted.

F probes measure the thickness of non-magnetic
coatings on magnetic substrates. They can be used

7.2 NON-FERROUS (N) PROBES
N probes measure the thickness of non-metallic
coatings on non-magnetic metals. They can be
used on anodising, paint, plastic coatings, powder
paint, etc. applied to aluminium, brass, non-
magnetic stainless steel, etc.
7.3 DUAL FERROUS/NON-FERROUS (FNF)
PROBES
FNF probes are dual function, F and N in one probe.
FNF gauges will automatically detect the type of
substrate
Alternatively the mode can be set manually - see

or metallised steel" on page 35.
