Introduction
The PosiTector 200 is a hand-held Coating Thickness Gage
that uses a non-destructive ultrasonic principle to measure
coating thickness on a wide variety of substrates. It consists of
a body (Standard or Advanced) and a probe (see Probes pg. 2).
This Quick Guide summarizes the basic functions of the Gage.

Probes
When powered-up, the PosiTector automatically
determines which probe is attached and does a
self-check.
To disconnect a probe from a body, slide the plastic
probe connector horizontally (in the direction of the
arrow) away from the body. Reverse these steps to
attach a different probe. It is not necessary to power-
down the Gage when switching probes.
PosiTector 200 probes are available for measuring
a wide variety of coating thickness applications.
nB probe - 13 to 1000 microns (0.5 to 40 mils)
Ideal for polymer coatings on wood, plastic, composites, etc.
nC probe - 50 to 3800 microns (2 to 150 mils)
Ideal for thicker coatings on concrete, fiberglass, etc.
nD probe - 50 to 7600 microns (2 to 300 mils)
Ideal for thick, soft (attenuative) coatings such as polyurea
Range limits apply t p lymer c atings nly.
Couplant
Additionally, the PosiTector accepts a number of probe types
including magnetic and eddy current coating thickness, surface
profile, environmental, salt contamination, shore hardness and
ultrasonic wall thickness probes. For the latest information on
probe interchangeability, see www.defelsko.com/probes
NOTE:
Couplant is required to propagate ultrasound into the coating.
Water is a good couplant for smooth coatings. Use the supplied
glycol gel for rougher coatings. While it is unlikely that the
couplant will damage the finish or leave a stain on the surface,
we suggest testing the surface by using the couplant on a
sample. If testing indicates that staining has occurred, a small
amount of water can be used instead of couplant. Consult the
aterial Safety Data Sheet available on our website and your
coating supplier if you suspect the couplant may damage the
coating. Other liquids such as liquid soap may also be used.

1. Remove the protective rubber cap from probe.
2. Power-up Gage by pressing the center navigation button.
3. Apply couplant (pg. 2) to the surface
of the part.
4. Place the probe FLAT on the surface
and press down.
5. Lift the probe when you hear a double
BEEP, - OR - leave probe on the surface
in the same location for continuous
measurements.
6. When completely finished, wipe the probe clean of couplant
then return the Gage to the protective pouch. There is no
need to disconnect the probe from the PosiTector during
storage.
Verify accuracy (pg. 4) at the beginning and the end of each shift,
or if the gage is dropped or suspected of giving erroneous
readings.
How to Measure
Couplant
Probe
Coating 1
Substrate
Coating 2
The PosiTector 200
interprets the largest
“echo” within the
selected range as
the coating/coating
or coating/substrate
echo.
PosiTector 200 probes emit a high frequency sound pulse that
travels into the coating via a coupling gel and reflects from ANY
surface that is different in density. Coating thickness readings are
obtained by measuring the time taken for the ultrasonic signal to
propagate from the probe to the coating/substrate interface and
back. The travel time is divided by two and multiplied by the
velocity of sound for the coating to obtain the thickness of the
coating.
PosiTector 200 - Theory of Operation

Calibration, Verification and Adjustment
Three steps ensure best accuracy…
1.Calibration - typically done by the manufacturer or a
qualified lab. All probes include a Certificate of Calibration.
2.Verification of Accuracy - as done by the user on known
reference standards such as the included plastic shims, test
block or optional coating thickness standards.
3.Adjustment - to a known thickness.
Calibration
Calibration is the controlled and documented process of
measuring traceable calibration standards and verifying that the
results are within the stated accuracy of the Gage. Calibrations
are typically performed by the Gage manufacturer or by a
certified calibration laboratory in a controlled environment using
a documented process.
Verification
Verification is an accuracy check performed by the user using
known reference standards. A successful verification requires the
Gage to read within the combined accuracy of the Gage and the
reference standards.
Adjustment
Adjustment, or Calibration Adjustment is the act of aligning the
Gage's thickness readings to match that of a known reference
sample in order to improve accuracy of a gage on a specific
coating. See Thickness pg. 6

5
The PosiTector 200 interprets the largest “echo” or “echoes”
within the selected range as the coating/coating or
coating/substrate echo. If the coating thickness is outside this
range, incorrect or dashed readings may occur.
I PORTANT:
Cal Settings Menu
The probe must be periodically zeroed using the Zero menu option
to compensate for both extreme temperature and probe wear
effects. Before using, allow the probe to reach ambient temperature.
Wipe the probe clean of couplant.
If measurements will be made in extreme hot or cold temperatures,
it is recommended to Zero the probe in the working environment.
If measurements will be made on rough substrates, it is
recommended to periodically Zero the probe to compensate for wear.
Zero
Set ange
The measuring range of each probe can be changed depending
on the specific application or the expected thickness range of the
coating system.
For most applications, the default range values do not have to
be adjusted. But some conditions, like surface roughness, may
cause the Gage to display very low or non-repeatable readings.
In this case, the low range may be increased to cause the Gage
to only display readings above the Lo value set by the user.
To adjust Set ange values...
1. Select or .
2. Use the (-)(+) buttons to decrease/increase the displayed value.

The PosiTector 200 measures most polymer coatings accurately
out-of-box with no adjustment required.
To determine if an adjustment is necessary, select a coating
sample of known thickness as close as possible in composition to
the intended application. For best results, the thickness of the
sample should be equal to or slightly greater than the maximum
expected thickness of the coating to be measured.

Graphics
When selected, the Gage displays
a graphical representation of the
ultrasonic pulse as it travels through
the coating system.
As the probe is depressed and the
ultrasonic pulse travels through the
coating system, the pulse encounters
changes in density at the interfaces
between coating layers and between
the coating and the substrate.
These interfaces are depicted by a "peak". The greater the
change in density, the higher the peak. The more gradual the
change in density, the greater the width of the peak. For example,
two coating layers made of essentially the same material and
"blended" would result in a low, wide peak. Two materials of very
different density and a well-defined interface would result in a
high, narrow peak.
The PosiTector 200 chooses the highest peak (single layer) or
peaks (multi-layer) within the Set Range. For example, if the
number of layers is set to 3, the three highest peaks would be
identified with small red triangles. The peak values are also
displayed numerically as thickness measurements.
The Graphics display can also be accessed using the
Set ange menu option.
Use the navigation Up (move left) and Down (move right) buttons
to highlight icons on the graphic display.
Zoom - Visually magnifies the waveform of the displayed
peaks for more visibility. Pressing the (+) or (-) button repeatedly
will increase/decrease the zoom.
Set ange - Press the (-) or (+) buttons to adjust the
Gage’s Lo or Hi measuring range. (pg. 5)

Las sondas PosiTector 200 emiten un pulso de sonido de alta
frecuencia que viaja por el revestimiento a través de un gel
acoplante y se refleja en CUALQUIER superficie que tenga
densidad diferente. Las lecturas de espesor de recubrimiento se
obtienen midiendo el tiempo que necesita la señal ultrasónica para
propagarse desde la sonda a la superficie de recubrimiento o
sustrato y regresar. El tiempo de transmisión se divide en dos y
se multiplica por la velocidad del sonido en el recubrimiento y así
obtener el espesor del recubrimiento.

El acoplante es necesario para propagar el ultrasonido en el
recubrimiento. El agua es un buen acoplante para revestimientos
lisos. Utilice el gel de glicol suministrado para revestimientos más
ásperos. Si bien es improbable que el acoplador dañe el acabado
o deje mancha en la superficie, le sugerimos que realice una
prueba sobre una muestra. Si la prueba indica daño en la
superficie, puede utilizar una pequeña cantidad de agua en lugar
del acoplante. Consulte la hoja de datos de seguridad del material
disponible en nuestro sitio Web. Contacte a su proveedor de
recubrimiento si sospecha que el acoplante puede dañar el
revestimiento. También pueden utilizarse otros líquidos como el
jabón líquido.
