most widely used measurement methods,
magnetic inductance and eddy current, in a
dual mode device that can measure the coating thickness of almost any non-magnetic
coating on both ferrous (magnetic) and nonferrous (non-magnetic) substrates.
Since the unit is able to automatically
determine the substrate and use the appropriate measurement circuit, this enables
instant, non-destructive testing on painting,
plating, anodizing and organic coatings with
accuracy up to 0.1 um. Such testing takes less
than a second to display the measurement.
Because the key to providing accurate,
repeatable measurements is the operator's
ability to reliably make consistent contact
between the instrument and the test surface,
the unit also utilizes a spring-loaded probe
to generate a consistent contact pressure
with the measured surface. This integrated
probe also includes built in edge guides to
enable easy measurement of even curved and
edged surfaces. To ensure device stability
during measurement, the foot of the probe
is also designed to provide a firm platform
when placed onto the test piece.
A number of other design considerations in
handheld coating thickness gauges can also
simplify measurement and improve versatility.
In order to improve accuracy and durability on the aerospace factory floor or in the

field, it is best for the unit to have no moving parts, other than the probe. Similarly,
the unit should be impervious to vibration, with measurement independent of
its orientation.
To save time during the testing process,
it's recommended to utilize a unit with a
large screen that enables the quick reading
of results. Those results should be able to
be stored in the gauge and transferred to
a computer and/or printer for documentation and averaging purposes. An instrument
that stores many test measurements is best
so operators can perform numerous tests
before downloading the results.
Easier, more accurate aerospace coating
and plating measurement with handheld
units will help to improve quality checks
wherever needed. So, defects can be immediately detected and corrective action
undertaken to minimize scrap and faulty
components or aircraft.
