Moisture  detector FMW-T
to measure humidity without causing any damages in the material
The humidity detector FMW-T covers all your needs while measuring moisture contents in all types of wood and building materials. The humidity detector FMW-T works without causing any damage to the material and it is mainly employed to measure building walls. When you have to choose a humidity detector it is very important to take into consideration if the surface can be affected or if it has to be in perfect condition after the measurement. Humid areas can produce mould in houses. These areas are easily detected. You will also measure humidity in wood, as for instance in parquet floors.
The humidity detector FMW-T has a compact design and is very easy to use. These characteristics turn the humidity detector into an irreplaceable tool for professional builders, technicians, etc.
Three-step measuring process:

- Turn-on and zero setting
- Fitting of wood thickness (selected from memory)
- Measuring and reading of moisture content

Adjustments:

- MAX, memory or Scan mode
- Entry of the specific weight of wood from 250 ... 1100 kg/m3 in 10 kg intervals
- Relative values for building materials

Functionality / Measuring principle
The humidity detector FMW-T for wood is guided by a microprocessor-unit to quickly determine moisture content in wood and building materials. The humidity detector FMW measures moisture content when the upper frontal sensor is placed on the material for half a second. It is also possible to measure through paper or paints.
Humidity is determined by contact using a high-frequency technique. Measurements can be taken without damaging the material surface. Therefore, this detector is specifically suited for the use on finished products or for fast controls on site.
The material you want to measure is not important. You will only need to put the frontal side of the detector on the material such as: balsa, beech, birch, cedar, oak, pine, fir-tree, mahogany, lime-tree etc or building materials such as parquet.
Characteristic curves of wood and basic indications for measuring
Below you will see an extract of the characteristic curves in alphabetical order of all the most important wood types (they are stored in the humidity detector). We can also send another list with more wood types.
Softwood
-  Fir
- Canadian Fir (east, west)
- Agathis (heavy, light)
- Alcere
- Alerce (European, Japanese, Russian)
- Alerce (American, East, West)
- Red Cedar
- Douglasie (heavy, light)
- Mañio
- Pine (European, Nordic)
- Pine (light, heavy, Caribbean, American)
- Pine (European, Nordic, Kern, Spint)
- Pine (French)
- Pine Parana
- Pine Radiata
- Pine Sitka
- Pine Sugar
- Pine Weymouth
- Yellowwood
- Redwood (Californian, heavy, light)
- Sugi
Attention: All the characteristic curves of the wood types of this column and the adjoining one are stored inside the humidity detector FMW-B. They can be displayed by introducing the corresponding gross densities. A chart with all the materials and wood types will be included in the delivery.
To take into account:
While measuring moisture content in wood, the result will be more accurate on smooth surfaces. The measuring value will grow on chips or knots. If measurements are taken on breaks, the humidity value will be lower in relation to the real humidity value (absolute humidity).
In both cases, you will have to measure near the area which is going to be measured.
Measurement accuracy:
Wood has an inhomogeneous composition. Therefore, gross density oscillations can be produced when measuring the same wood type. Therefore, you will have to take various humidity measurements - the measurement result will be the mean value calculated by the detector
Wood surface:
In rough surface wood types, the result displayed in the humidity detector can be lower.
Fiber direction:
The result will not be affected if the measurement is taken either in the fiber direction or against the fiber direction. 
Measurement depth:
The measurement depth is 25 mm. If the wood is very thin (e.g. < 1 cm thickness) measurement will be carried out through the wood. The material on the wood will also be measured partially.
Measuring surface:
During the measurement the humidity detector has to be on the surface which is going to be measured in order to avoid mistakes with results.

Building materials
For building materials it is possible to introduce "0" value. For this detector, there is only a single characteristic curve (mean characteristic curve). With the humidity detector FMW-B you will be able to easily determine humid zones in floors, walls, etc for a relative measurement in wet or weak areas.
