To disconnect a probe from a body, power-down the
instrument and slide the plastic probe connector
horizontally (in the direction of the arrow) away from the
body. Reverse these steps to attach a new probe.
When powered-up, the PosiTector automatically
determines which probe is attached and does a
self-check.
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
Range limits apply to polymer coatings only.
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.

Additionally, the PosiTector accepts a number of probe types
including magnetic and eddy current coating thickness, surface
profile, environmental and ultrasonic wall thickness probes.
