MF-100 Moisture Meter
Item No. 2399955
Intended Use
This non-invasive digital moisture meter is ideal for measuring moisture content in concrete,
wood and other building materials. This helps to check if the surface is ready for painting or
covering. Large surface areas can also be quickly and effectively measured by using the alert
function. The user can concentrate on the measured object without having to constantly read
the measurement values on the display. The device produces a beeping noise if the moisture
level exceeds the threshold value.
This device features a wide measuring range, with a penetration depth of about 20 - 40 mm.
It has min / max display and a low battery indicator. The device is powered by three AAA bat-
teries.
Unauthorised conversion and/or modification of the device are inadmissible because of safety
and approval reasons. Any usage other than described above is not permitted and can damage
the product and lead to associated risks such as short-circuit, fire, electric shock, etc. Please
read the operating instructions thoroughly and keep them for further reference.

these operating instructions which must be observed.
Safety Instruction
We do not assume liability for resulting damages to property or personal in-
jury if the product has been abused in any way or damaged by improper use
or failure to observe these operating instructions. The warranty/ guarantee
will then expire!
The icon with exclamation mark indicates important information in the op-
erating instructions. Carefully read the whole operating instructions before
operating the device, otherwise there is risk of danger.
a) Personal and Product safety
• The product is not a toy and should be kept out of reach of children!
• Condensation may form in the device when transported from a cold to warm envi-
ronment. This may result in false measurement. Allow the device to get acclimated
to the new environment before operation.
• The product must not be subjected to heavy mechanical stress.
• The product must not be exposed it to extreme temperatures, direct sunlight, in-
tense vibration, or dampness.
• If there is reason to believe that safe operation is no longer possible, the device is
to be put out of operation and secured against unintended operation. Safe opera-
tion is no longer possible if the device:
- shows visible damages,
- no longer works,
- was stored under unfavourable conditions for a long period of time or
- was subject to considerable transport stress
b) Battery safety
• Correct polarity must be observed while inserting the batteries.
• Batteries should be removed from the device if it is not used for a long period of
time to avoid damage through leaking. Leaking or damaged batteries might cause
acid burns when in contact with skin, therefore use suitable protective gloves to
handle corrupted batteries.
• Batteries must be kept out of reach of children. Do not leave the battery lying
around, as there is risk, that children or pets swallow it.
• All the batteries should be replaced at the same time. Mixing old and new batteries
in the device can lead to battery leakage and device damage.
• Batteries must not be dismantled, short-circuited or thrown into fire. Never re-
charge non-rechargeable batteries. There is a risk of explosion!
c) Miscellaneous
• Users are responsible for the measurement results from this device. We do not
guarantee not accept liability for the measurements. Under no circumstances will
we accept the liability for damages caused by the application of the measurement
results.
• Repair works must only be carried out by a specialist/ specialist workshop.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.

Inserting batteries
This moisture meter is powered by three AAA batteries.
1. Using a screwdriver, remove the battery compartment cover at the back of the meter.
2. Insert three AAA batteries, while observing the correct polarity.
3. Replace the battery compartment cover.
4. Replace batteries when the low battery indicator (9) illuminates on the LCD panel.

Operation

a) General information before measurement
• The moisture level is an average value, which is influenced by the moisture at the exterior
surface and the interior core of the material. If there is visible surface moisture or water,
wipe off any excess and let dry for a couple of minutes before measuring.
• Other elements may also affect the reading. Before measurement, the measuring surface
must be cleaned of any residual paint, dust, etc.
• Hold the meter as far back as possible to avoid moisture influence from your hand.
• The meter is not designed to measure metal or other materials which are strong conductors.
If embedded metal (e.g. nails, screws, cables, pipes etc) is within the measuring field of the
sensor, the readings will increase significantly.
• If the spherical head is placed at a wall corner, the reading may be higher as two or three
surfaces are within measuring distance. To avoid interference, maintain a minimum dis-
tance of 8 to 10 cm from other surfaces.
• Place the spherical head on smooth surfaces, Rough surfaces product inaccurate readings.
• The penetration depth of the device is 20 to 40 mm. Depending on the density of the ma-
terial, reading of inner depth is not possible. If the material is less than 2 cm thick, the
moisture content value may not be as accurate due to influence from adjacent material.
• The spherical head must be kept perpendicular to the surface being measured.
