DeFelsko PosiTector 200 Guide D'utilisation page 4

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.
B probe - 13 to 1000 microns (0.5 to 40 mils)
Ideal for polymer coatings on wood, plastic, composites, etc.
C probe - 50 to 3800 microns (2 to 150 mils)
Ideal for thicker coatings on concrete, fiberglass, etc.
D probe - 50 to 7600 microns (2 to 300 mils)
Ideal for thick, soft (attenuative) coatings such as polyurea
NOTE:
Range limits apply to polymer coatings only.
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
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
Material 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.
