Twin Element Probes
Probe Type
Details Applications Identification
S3C
3.5 MHz 13 mm
(0.5”)
Suitable for
measurement on thinner
sections where surfaces
are relatively rough
Orange Band
S5C
5.0 MHz 13 mm
(0.5”)
Ideal for thin sections
without heavy corrosion.
Black Band
S5A
5.0 MHz 6 mm
(0.5”)
The higher frequency
and narrower beam
makes this Probe ideal
for measuring small-
bore tubing, thin section
plate and other areas
where access is limited.
Black Band
Lower frequency probes offer better penetration on heavy
corrosion/coatings.
Probe Measurement Ranges
Each probe type has a defined measurement range to be aware of.

To measure thicknesses on tall thin cylinders or columns the height-width ratio should be no
less than 1.0:0.6 (Height:Width) otherwise side reflections prevent measurement.
