Information about the device
Device description
The material moisture measuring deviceT660 is a dielectric
moisture indicator, which can be used for the quick and non-
destructive localization of humidity or moisture distributions.
The device enables the detection of near-surface moisture in
walls or flooring. The measured values will be displayed in real
time.
A minimum, maximum and average function is available for the
direct analysis of the measured data. Besides, the currently
measured value can be recorded via the hold function.
The device further features an alarm function. Once the preset
limit value is exceeded, the device alerts the user through
emitting an acoustic signal!
The device is suited for the preliminary check of the building
materials' readiness for covering for subsequent measurements
according to the calcium carbide method (CM measurement).
The moisture indication allows the localization of the most
significant measuring spots to extract material for the CM
measurement.
You can connect the device to a computer by using the USB
cable included in the scope of delivery. Then you can extract
and analyse your measured results with the optional
MultiMeasure Studio software.

moisture measuring device T660
Measuring principle
The measurement is effected according to the dielectric
measuring principle.
Notes regarding the measurement principle
• The measurement results are only to be used as reference
for a rough orientation.
• An important variable influencing the measured value is
the bulk density of the good to be measured. The higher
the bulk density, the higher the measured value.
• Before measuring, the measuring point is to be cleared of
any impurities (e.g. paint residues, dust).
• If the material to be measured contains metal (e.g. nails,
screws, lines, pipes, etc.) and is situated within the
sensor's measuring field, the measured value skyrockets.
In that event the measurement is not conclusive.
• When the ball head is held to corners (e.g. window
frames), the measured value is generally higher, because
there is more matter in the measuring head's stray field.
Toward a corner a distance of more than 8 to 10cm has to
be observed.
• During the measurement always hold the measuring
head(6) in a vertical position to the measured material,
press it to the surface and do not tilt it.
• Rough surfaces will always result in a too low measured
value.
• Depending on the material's bulk density, the device's
impact depth amounts to 20 to 40mm. Conclusions
regarding zones located at a lower level cannot be drawn.
• With material thicknesses of less than 20 mm there is a
danger of humidity values from adjacent material layers
affecting the measured value.
• The dielectric measurement method's main area of use
consists in comparative measurements at the same
construction material or similar components. Therefore,
this method is well suited for the examination of water
damage, leak detection and the localization of moisture
zones for the purpose of marking the measuring spot for
CM measurements.
Measured value assessment for wood
The measurement result is either in the dry or the saturated
area.
Saturated means that in addition to the water bound within the
wood there is further liquid. If there is, hence, a measured value
of more than 80, the wood is most like soaked.
Display [digit] Wood moisture zone
< 50 digits dry
> 80 digits limit to the saturated range
Since the measurement value displays of the dielectric
measurement method – depending on marginal conditions – are
subject to great fluctuations, a resistance measurement is
always preferable, in particular for the determination of wood
moisture.

10 EN
moisture measuring device T660
Measured value assessment for building material
For building materials the measurement results of the dielectric
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.
Key
a Moisture content (M%)
b Measured value (digits)
Anhydrite floating screed (conversion: M% = CM%)
Cementitious screed (conversion: CM% = M% -1.5 to 2)
C 30/37 concrete (conversion not possible)
The spread of the achieved measurement results for the
dielectric measuring method is clearly higher than for the
resistance measuring method. The dielectric measuring method
is not suited for the quantitative, but only for the qualitative
moisture measurement in near-surface areas.
The indicated measured values are not the result of a qualified
moisture measurement as per VOB (German Construction
Contract Procedures) or relevant specialist regulations.
The measured values are only to be interpreted as indicators
(dry, damp, wet).
For building materials the measurement results of the dielectric
measuring method can only be used as reference for a rough
orientation.

< 40 digits dry
