Measuring principle
During moisture measurement according to the resistance
principle an electric measuring current is generated within the
measuring device, which is conducted through the material to
be measured by means of electrodes.
With an increasing water content of the measured material to be
examined the resistance drops and conductivity builds up.
If the material to be measured has a high resistance, the
moisture content is low.
If the material to be measured has a low resistance, the
moisture content is high.
Thus, moisture measurement according to the resistance
principle is an indirect measurement method, since the humidity
is deduced from the conductivity of the measured material.
Wood moisture measurement
Every type of wood has a distinct conductivity. In order to take
this fact into consideration for the measurement, every wood
type comes with a material code that can be set.
The wood's conductivity is further influenced by the wood
temperature. In order to take this fact into consideration for the
measurement, the wood temperature can also be determined.
The wood temperature is to be determined before moisture
measurement and set accordingly.
The measuring device comes equipped with an internal
temperature compensation. The resistance curves of the
selected wood type are automatically adapted depending on the
set wood temperature.
Error sources
During resistance measurement the accuracy of the
measurement method needs to be examined. Two fundamental
types of error sources become apparent within the measuring
range from 0 to 100M%.
• There is one error stemming from the measuring principle
of the resistance measurement. This is particularly
noticeable in case of high resistance values (low
conductivity at less than 5M%). Due to the low measuring
currents the measurement value display is i.a. increasingly
falsified by molecular attraction. Listed below are the
principle-related measurement errors:
Measured value Error
0 - 5 M% 0.8 M%
6 - 30 M% 0.2 M%
31 - 100 M% 0.1 M%

EN 11
moisture measuring device T510
• The other typical error source to be considered is material
characteristics. This is particularly noticeable in case of
high moisture contents above the fibre saturation point
(high conductivity above 30 M%). Owing to the irregular
cellular structure of various wood types and the i.a.
resulting irregular water retention within and outside of the
cells, these measured values in part substantially deviate
from the actual moisture contents. It is, however, not
possible to put a precise number on these deviations, even
though the principle-related accuracies with 0.1M%
suggest a higher accuracy than for the medium measuring
range from 6 to 30M%.
When looking at both error sources, one can conclude, that the
resistance measurement method is particularly well suited for
the determination of the moisture content between 6 and 30M
%.
Notes regarding the wood moisture measurement
• Make sure you have set the correct type of measurement
(wood).
• Make sure that the correct material code was selected.
• Prior to the actual measurement process, check the
temperature conditions. To do so, for instance a pyrometer
is to be used for measuring the surface temperature of the
wood type, which should then be compared with the wood
temperature set in the device. If both temperatures are
identical, measuring can be started.
If the wood temperature is higher than the value set in the
measuring device, a higher wood moisture than really
there will be displayed as a result.
• When measuring sawn timber, observe the instructions of
DIN EN 13183-2.
• Always insert the measuring tips transverse to the wood
fibre direction.
The conductivity transverse to the wood fibre direction is
lower than that in line with it.
Depending on the type of wood it varies by the factor 2.3
to 8.
• When selecting the measuring positions observe the
following:
– Always measure the material moisture at three different
positions in order to achieve a sufficient accuracy by
means of the arithmetic average.
– Do not measure the face, because there are mainly dry
areas.
– Preferably do not measure at cracks, branches or resin
pockets either.
• Oily and/or aqueous timber preservatives affect the
measurement result.
• If possible, do not measure wood with a temperature
below -5°C. Too low wood temperatures distort the result
of the measurement.
• Avoid static charge of the material to be measured due to
friction. Static charge distorts the measurement result.
• With a wood moisture of less than 10%, electrostatic
forces can appear at the good to be measured. This can
falsify the result of the measurement. Experience has
shown that this occurs at the outlet of veneer drying
plants. Remove the static charge by use of suitable
grounding measures.
• The temperature value set within the device must be
identical to the wood temperature.
Example:
With a set temperature value of 20°C and a wood
temperature of 30°C the measurement result would be
distorted upwards by approx. 1.5%.
• The measurement's accuracy depends on the contact
pressure of the measuring tips. The measuring tips must
be connected to the wood in a way that the contact
resistance is small as compared to the measuring
resistance.
• The measurement results ought to be checked on a
sample basis by means of the Darr test.
Building moisture measurement
The electric conductivity of a dry, mineral construction material
(e.g. cementitious screed) is very low. When the building
material absorbs water, the conductivity of the material can
quickly increase or the resistance decrease.
What needs to be considered for the assessment of the
measurement results is that the results are affected by the
material composition of the measured goods:
• The presence of soluble salts can distort the measurement
result substantially.
The more salt is present, the higher will be the displayed
measurement value.
• Yet another variable for the evaluation of the results is the
connection of the electrodes with the construction
material. In case of mineral, porous building materials,
slight electrode contact can cause a comparatively high
contact resistance. This can falsify the result of the
measurement.
The accuracy of the measurement results is thus lower for
mineral construction materials than for wood.
Building moisture measurements allow only qualitative
conclusions about the moisture (dry, damp, wet).
Quantitative conclusions about the moisture content of the
mineral material to be measured can only be drawn by applying
the Darr procedure or the CM method.

Notes regarding the building moisture measurement
• Make sure you have set the correct type of measurement
(build).
• For measuring, the temperature of the building material
ought to be in the range of 20°C.
• Observe disruptive influences due to electrically
conducting salts in the material:
Building-related moisture issues often occur in liaison with
water-soluble salts. Salts further the conductivity of
construction materials. During the measurement, the
building material has a lower resistance value.
Consequently, a too high measured value will be displayed.
• Observe disruptive influences due to electrically
conducting substances:
If a construction material contains electrically conducting
substances, it also has a lower resistance value, which
then simulates high moisture values. Consequently, a too
high measured value will be displayed.
From visual inspection it is usually not apparent, whether
there are any electrically conducting substances inside the
construction material. Some of the main error sources here
are in particular reinforcements, metal laminations and
conducting insulation such as slag in timber beam ceiling
constructions. Especially in case of insulation materials
with metal lamination, measured values are often
misinterpreted during the resistance measurement.
Measured value assessment building moisture
measurement
For the measured value assessment of building material, the
measurement results of the resistance measuring method can
only be used as reference for a rough orientation.
Conclusions with respect to absolute humidity in mass % (M%)
can only be drawn for measurements, performed with the exact
same marginal conditions and compositions of the building
material as indicated for the test set-up in the chart below.
This graph was created in collaboration with the Institute of
Building Materials Research of the RWTH Aachen (IBAC) and
illustrates the correlation between the measured value and the
mass-related moisture content of the examined building
materials. The presentation of the metrological results in this
form now permits a proper comparison of the measured value
and the actual moisture content. The list is limited to the most
commonly used mineral building materials. The measured
values relate to a reference temperature of 23 °C.

Plaster
The determination of the moisture content of plaster calls for
separate examination. As can be seen from the following chart,
the volume-based moisture content of plaster changes little at
air humidity values between 0 and 0.8(80%). However, when
exceeding the level of 0,8 (80%), the moisture content
skyrockets.

b Water content uV in %
This was also confirmed by the calibration measurements of the
Institute of Building Materials Research (IBAC). Therefore, one
can conclude, that a direct correlation between measured value
and mass-related moisture content is not possible. As sufficient
criterion for the classification of the measured values it can
however be stated, that plaster can be considered dry, when the
measured resistance value is smaller than 30 digits. When
evaluating the measured values it is imperative to observe that
different marginal conditions prevail for every measurement.
Important variables influencing the worth of the measured value
are the connection of the electrodes to the material to be
measured, the material temperature, the construction material's
composition, salt loading and aggregates.
For construction materials not listed, usually sufficient
conclusions can be drawn owing to local reference values. As a
consequence, the affected damp area can be narrowed down to
such an extent that a comparative measurement is carried out
at an evidently dry wall or floor area as basis of valuation.
By use of the higher measured values of the area to be
assessed, the spreading of the damp area can well be
determined.
Reference values for the assessment of areas damaged by
water
In case of water damage a resistance measurement can be
carried out to enable an evaluation of the area to be dried.
Based on the factual moisture content and the changeable
marginal conditions, the following table can be used to assess
the necessity for drying by use of technical means.
Here, one has to observe that the measurement results
constitute only one component of a comprehensive damage
diagnosis. The experience of the evaluator and local
circumstances play just as vital a role as the documentation of
the measurement results. The documentation further allows to
demonstrate the success of a technical drying procedure.
