Resipod models
Two versions of Resipod are available:
- The 50 mm probe spacing model
conforms to the accepted industry
standard.
- The 38 mm (1.5”) probe spacing model
conforms to the specification of the
AASHTO T 358 surface resistivity test
method.
Due to the inhomogeneous nature of concrete, a wider probe spacing is preferred as it allows a
more homogeneous flow of the measuring current. However, this usually has to be offset against
the need to avoid the influence of reinforcing steel (see chapter 3). 50 mm spacing is typically
considered a good compromise.
Both units operate with a digitally generated 40 Hz alternating current at 38 V max.

5. Indication of scaled reading
Measured resistivity
Display resolution depends on the measured resistivity and the nominal current flowing. See
technical data.
Battery status
The battery status symbol will be displayed when the accumulator is at 10% of its capacity.
Otherwise it is blanked out.
