2 Getting started
Note: When shipped, battery packs are not fully charged. Prior to use, please
charge the battery completely. To prevent the battery from damage, avoid deep-
discharging or storing it long-term when empty. Store the instrument at room tem-
perature and charge the battery fully at least once a year.
2.1 Resipod Basics
Charging the Resipod
The battery status symbol will be displayed when the accumulator is at 10% of its capacity. In this
case it is still possible to make a large number of measurements, but it is advisable to recharge
the battery by connecting the unit to a wall adaptor or a PC via the USB port. A complete charging
cycle will last approximately 6 hours. Autonomy is > 50 hours.
Operation - Power ON / OFF
Press the “Hold” button on the side of the Resipod to power on.
Press and hold the button for >2 s to shut the unit off (auto shutdown after 10 min. of stand-by)

Performing a reset
A small reset button is located beneath the watertight cover for
the USB port. If the instrument has locked up or does not respond,
pressing this button with a paper clip will perform a reset.
2.2 The Resipod Measurement Principle
The Resipod is an evolution of the industry standard CNS Farnell RM MKII resistivity meter,
operating on the principle of the Wenner probe.
The Resipod is designed to
measure the electrical resistivity of
concrete. A current is applied to the
two outer probes and the potential
difference is measured between
the two inner probes. The current
is carried by ions in the pore liquid.
The calculated resistivity depends
on the spacing of the probes.
Resistivity ρ= 2πaV/l [kΩcm]

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.
2.3 The Resipod Display

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.

Range indication
Resipod has two current ranges.
Range indicator to the right: 200 µA range
Provided the external resistance (contact resistance of the
two outer probes plus resistance of the specimen) is not too
high, Resipod will drive the maximum current (200 µA) through
the specimen.
Range indicator to the left: 10 - 50 µA range
When the external resistance is too high, Resipod
automatically switches to supply 50 µA.
For even higher resistances, the unit applies the maximum voltage across the outer electrodes
and senses the resulting current through the specimen. In this case, the displayed resistivity is a
calculated value (voltage across inner probes divided by current sensed in outer probes), and the
reading is rounded to the nearest kΩcm. This mode works down to a current of 10µA (1 segment
lit). Below this range “OL” is indicated. (See “Indication of poor connection” below).
Current indication
All five segments lit indicate that the full 200 µA or 50 µA are
being driven into the test object. When this is not possible,
(see above), The display indicates this current to the nearest
multiple of 10 µA.
Indication of scaled reading
The ResipodLink software allows the user to introduce a correction to the displayed reading. This
is typically used together with a non-standard probe spacing, in which case the probe spacing
value used to calculate the resistivity must be changed. It may also be used to introduce a correc-
tion based on a form factor if desired.
Whenever the apostrophe to the right of the kΩsymbol is lit,
it indicates that a correction factor has been applied.

3 Measuring Resistivity with Resipod
Preparing the concrete surface
The concrete surface must not be coated with any electrically insulating coating, and it should be
clean. The rebar grid beneath the surface should be marked out with the help of a rebar locator
(e.g. Profoscope). If the concrete is completely dry it will not be possible to make a measurement
as the current is carried by ions in the pore liquid, (See 2.2). Therefore it may be necessary to wet
the surface.
3.1 Making a Measurement
A good connection between the
instrument and the concrete surface is
the most important factor for obtaining a
reliable measurement. Dip the contacts
in water several times before making a
measurement – use a shallow container
so you can press against its bottom
– this will fill the reservoirs. Press the
Resipod firmly down until the outer two
rubber caps rest on the surface to be
tested.
Indication of poor connection
In the case of a poor connection, the Resipod will display one of the following alerts.
“Open Line” indication
Bad connection of the two outer probes to the concrete
surface. No measurement possible.
Inner two probes are not making contact.
(check for holes or dry spots on the specimen)
Or Sample resistivity <1kΩcm
Material resistivity is extremely low.
Overflow
The measured resistivity is out of range. This limit is
dependent on the spacing, but it is typically a resistivity of
>1000 kΩcm.
Contact selection
The steel probe tips are rugged and may be used to scratch away a thin layer of plaque on the
surface in order to make a better connection. The size of the contact however, means it is not
always possible to drive the full 200µA into the concrete to obtain the maximum measurement
resolution.

8

In order to enable this, the Resipod is also supplied with large surface area foam contact pads.
Simply snap out the steel contacts and replace with the foam pads. They should likewise be moist-
ened before measurements.
Hold and Save function
Once a stable reading has been achieved, click the hold button on the side of the Resipod to freeze
the actual measurement on the screen.
Hold
• The display flashes to indicate the “hold” status.
• Click the hold button again to return to “live” mode or:
Save
• Click the save button to record the measurement. An “m” appears to indicate that a new
reading has been stored in this memory location. (In the example, the reading is the first reading
stored in memory object 2.)
3.2 Memory function
The Resipod can store up to 512 measurements. The memory is arranged so that the readings are
stored in objects from 1 to 19. Each object can contain up to 99 readings.
Object 1 - Reading 1 Object 19 – Reading 99
You may check the last entry “Object – Reading” number simply by pressing the “Save” button
when the instrument is not in hold modus.

9

Moving to the next Object
To move to the next object simply switch the Resipod off and then on again.
Note: The Resipod will always move to the next object when you switch it on and off.
If you wish to carry on measuring in the previous object, simply delete the current
reading as described below and you will be returned to the previous object.
Deleting a reading
The last reading has been stored in Object 4 – Reading 3.
To delete this reading, press the hold button to set the display
blinking.
(If the Resipod is held in the air for this the “open line” screen
will be displayed and will blink.)
Press the “Save” button for 2 seconds to delete the reading.
Object 4 – Reading 3 has been deleted. The display shows a
small “c” to indicate the last reading has been cancelled. Subse-
quent readings can be cancelled this way, but only sequentially.
It is not possible to scroll back and delete an earlier reading.
Memory status indications
A number of special screens provide information about the status of the memory.
Object number is >19.
All 19 objects have been used. It is necessary to delete readings
before using the memory further (see above).
Reading number is >99
The current object is full. Move to the next object to store further
readings (see above).
Memory is empty.

4 Resistivity Measurements on Site
4.1 Influences
Influence of rebars on electrical resistivity measurements
The presence of rebars disturbs electrical resistivity measurements as they conduct current much
better than the surrounding concrete. This is particularly the case when the cover depth is less than
30 mm. As far as possible, reinforcement bars should not be directly beneath the probe and should not
run parallel to the probe. The recommended measurement orientation is determined by the spacing of the
rebars compared with the probe spacing.
The optimum orientation is to measure diagonally to the
rebars as shown. This is possible if the probe span is
less than the rebar grid spacing.
For the Resipod 38 mm, the probe span is
38x3 = 114 mm (4.5”)
For the Resipod 50 mm, the probe span is
50x3 = 150 mm (5.9”)
If the rebar spacing is so close that it cannot be
avoided, the influence of the steel can be minimized by
measuring perpendicular to the rebars as shown.
RILEM TC154-EMC: ELECTROCHEMICAL TECH-
NIQUES FOR MEASURING METALLIC CORROSION
recommends making 5 readings from the same location
moving the probe a few mm between each measure-
ment and taking a median from the 5 values.
Influence of aggregate size
As explained in 2.2, the current flows in the pore liquid of concrete. Ideally the probe spacing
should be larger than the maximum aggregate size as aggregate material is typically non-conduct-
ing. The variable spacing probe supplied with Resipod Geometric should be used for aggregate
sizes larger than the standard probe spacing.
Influence of temperature
The temperature of the concrete should be measured and recorded with resistivity measurements.
Resistivity decreases as the temperature increases. Reference values for resistivity measurements
are typically quoted for 20°C (68°F). Empirical studies have shown that a one degree increase in
temperature can reduce the resistivity by 3% for saturated concrete and 5% for dry concrete.
Influence of moisture content
A higher moisture content lowers the resistivity. This can be due to saturation or due to a change
in the water/cement ratio.

11
© 2017 Proceq SA
Influence of carbonation
Carbonated concrete has a higher resistivity than concrete without carbonation, however pro-
vided the depth of the carbonated layer is significantly smaller than the probe spacing, the effect
of this layer is small. Consequently if the carbonated layer is thick, it may be necessary to increase
the probe spacing to obtain good results.
4.2 Applications
Empirical tests and theory have shown that resistivity is directly linked to both the likelihood of
corrosion due to chloride diffusion and to the corrosion rate once depassivation of the steel has
taken place.
Estimation of the likelihood of corrosion
Resistivity measurements can be used to estimate the likelihood of corrosion. When the electrical
resistivity (ρ) of the concrete is low, the likelihood of corrosion increases. When the electrical resis-
tivity is high (e.g. in case of dry and carbonated concrete), the likelihood of corrosion decreases.
Empirical tests have arrived at the following typical values for the measured resistivity which can
be used to determine the likelihood of corrosion. These figures are for Ordinary Portland Cement
at 20°C.
When ≥100 kΩcm Negligible risk of corrosion
When = 50 to 100 kΩcm Low risk of corrosion
When = 10 to 50 kΩcm Moderate risk of corrosion
When ≤10 kΩcm High risk of corrosion
Indication of corrosion rate
The following interpretation of resistivity measurements from the Wenner four-probe system has
been cited when referring to depassivated steel (Langford and Broomfield, 1987).
> 20 kΩcm Low corrosion rate
10-20 kΩcm Low to moderate corrosion rate
5-10 kΩcm High corrosion rate
< 5 kΩcm Very high corrosion rate
Empirical reference values
A large body of empirical resistivity data has been collected by many studies over a number of
years. The data presented here is taken from “Test methods for on-site measurement of resistiv-
ity of concrete – a RILEM TC-154 technical recommendation” by Rob B. Polder. The values have
been converted to kΩcm to match the display of the Resipod. More details on the interpretation
of results may be found in that document.

Resistivity mapping
Mapping out the resistivity of a structure enables useful interpretations to be made by comparing
the values against those in the above table. Please note that the temperature correction described
earlier should be taken into consideration. If exposure conditions are the same, varying resistivity
values may indicate local variations of the water/cement ratio. If it is known that the concrete is
homogenous throughout the structure, then the resistivity measurements can be used to determine
how relatively wet and dry the various areas are.
Correlation to permeability
Studies have shown that resistivity can be directly correlated to chloride diffusion rate. On site
mapping of the resistivity of a concrete structure will identify the most permeable areas. Such
areas are more likely to be susceptible to chloride penetration. The Resipod model with 38 mm
spacing conforms to the AASHTO T 358 Surface Resistivity Test Method which uses surface
resistivity as an indication of the permeability of concrete. Details of the test can be found on the
official AASHTO website http://tig.transportation.org/Pages/SurfaceResistivityTest.aspx.
On site assessment of curing efficiency
Resistivity measurements may be used on site to determine premature drying of concrete. This
is a particularly important application in hot countries where premature drying out can lead to
structural weakening due to non-completion of the hydration reaction. The method uses the strong
dependence of resistivity on the humidity of the concrete. Site measurements are compared with
measurements made on a saturated reference cylinder to define a relative resistivity which can be
used to isolate the effects of humidity and thereby determine premature drying. Please refer to
“Electrical resistivity as a tool to on site assessment of curing efficiency – by L. Fernandez Luco,
C. Andrade and M.A. Climent (June 2009)”.
Resistivity measurements and cathodic protection systems
The effectiveness of a cathodic protection system depends very much on the resistivity of the
concrete. Mapping out the resistivity prior to installation allows the structure to be divided into
separate zones requiring different levels of current flow.

5 Quality Control Applications
The Resipod model with 38 mm spacing conforms to the AASHTO T 358 Surface Re-
sistivity Test Method which uses surface resistivity as an indication of the perme-
ability of concrete. Details of the test can be found on the official AASHTO website:
http://tig.transportation.org/Pages/SurfaceResistivityTest.aspx

5.1 Resipod Bulk Resistivity
The accessory comprises of a stand that allows the instrument to be conveniently mounted, cables
that are easily inserted into the rear connectors and the measurement plates with conductive foam
inserts suitable for 4”x8” cylinders.
The stand accommodates both Resipod versions (38 mm and 50 mm).

Cable Connection
The cables are simply attached as shown here.
Measuring the offset
The foam inserts provide the electrical contact to the cylinder, but they also have a resistance
which must be measured and compensated for to determine the true bulk resistivity of the cylinder
under test.
The resistance of the foam inserts varies with the pressure applied.
The resistances of the top and bottom inserts can be measured as follows:

The measured resistance is the sum of the resistance of the cylinder plus the two inserts, therefore:

Calculation of the Bulk Resistivity
Resipod displays a number in kΩcm. The number obtained from the Resipod display should be
divided by 2πa (where “a” is the probe spacing, i.e. either 3.8 cm or 5.0 cm). For a Resipod with
38mm probe spacing:
Cylinder size 2πa A (cm2) L (cm) A/L (cm)
4x8 23.88 81.07 20.32 3.99
The bulk resistivity ρ= K xRcylinder, where K = A/L
Example
Rcylinder = 52 kΩcm
Rcylinder (corrected) = 52 / 23.88 = 2.18 kΩ
Bulk resistivity ρ= K xRcylinder = 2.18 x 3.99 = 8.69 kΩcm
Bulk Resistivity in ResipodLink
ResipodLink offers the possibility to calculate K automatically and download it onto the Resipod
instrument, so that the display shows directly the correct value in kΩcm. See Chapter 9.
5.2 Resipod Geometric
Resipod Geometric is supplied with a stand for mounting the Resipod and a variable spacing
probe that allows probe spacing to be varied between 40mm and 70mm. This allows it to accom-
modate larger aggregate sizes.
The ResipodLink software (Chapter 9) allows the user to enter the correct probe spacing and also
a geometric correction factor to give the correct resistivity reading directly on the instrument.
The geometric correction factor for cylinders is designed to comply with the latest research in-
tended to extend the current AASHTO surface resistivity method to other sample geometries.
In addition to this the user also has the possibility to enter a self-determined correction factor.

8 Maintenance and Support
Functional Check
Correct functioning of the Resipod can be checked with the test strip provided. The test strip is
intended to be used by both Resipod models (38 mm,1.5” and 50 mm spacing).
The upper row allows the functional check using the full 200 µA range. The lower row allows the
functional check using the reduced 50 µA range. Resistors to the outer pads limit the maximum
current to approx. 20 µA, (only two segments in the current indicator strip are active).
The expected test results are summarized in the table below:
Current range Expected test result
38 mm (1.5”) spacing
Expected test result
50 mm spacing
200µA (upper row) 12 (±0.2) kΩcm 16 (±0.2) kΩcm
50 µA (lower row) 90 (±1.8) kΩcm 120 (±2.4) kΩcm

Cleaning of the probes and the body
The probes can be removed for cleaning, replacement or
for fitting test accessories, such as the variable spacing
probe. They’re snap fit, so simply pull them off. Be careful
not to lose the spring.
After cleaning, replace the probes by inserting them into
the shafts and snapping them firmly into place. Ensure the
fit by pressing on the rubber cap as shown in the figure.
Long caps go on outer probes.
Probes need not be kept moist when the unit is not in use.
The unit can be rinsed with water (make sure USB cover is
firmly in place). Since the instrument has an extremely high
input impedance, check that the underside of the case is
clean (dirt or salt deposits might create leakage currents
and yield faulty readings).
Note! The springs are intentionally long to ensure a con-
stant pressure on all four probes, while allowing a ± 4 mm
displacement on the inner tips to accommodate uneven or
curved surfaces.
