MF-100 Moisture meter
Item no. 1529788
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
batteries.
For safety and approval purposes, you must not rebuild and/or modify this product. If you use
the product for purposes other than those described above, the product may be damaged.
In addition, improper use can cause hazards such as short circuiting, fire, electric shock etc.
Read the instructions carefully and keep them. Make this product available to third parties only
together with its operating instructions.

• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed
if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height
can damage the product.
• Consult an expert when in doubt about operation, safety or connection of the
device.
• Maintenance, modifications and repairs are to be performed exclusively by an

• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.
b) Persons and product
• Condensation may form in the device when transported from a cold to warm
environment. This may result in false measurement. Allow the device to get
acclimated to the new environment before operation.
• 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.
c) (Rechargeable) batteries
• Correct polarity must be observed while inserting the (rechargeable) batteries.
• (Rechargeable) 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
(rechargeable) batteries might cause acid burns when in contact with skin,
therefore use suitable protective gloves to handle corrupted (rechargeable)
batteries.
• (Rechargeable) batteries must be kept out of reach of children. Do not leave
(rechargeable) batteries lying around, as there is a risk that children or pets may
swallow them.
• All (rechargeable) batteries should be replaced at the same time. Mixing old and
new (rechargeable) batteries in the device can lead to (rechargeable) battery

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
1. 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.
2. Other elements may also affect the reading. Before measurement, the measuring surface
must be cleaned of any residual paint, dust, etc.
3. Hold the meter as far back as possible to avoid moisture influence from your hand.
4. 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.
5. 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
distance of 8 to 10 cm from other surfaces.
