PCE รุ่นFMW-T เครื่องวัดความชื้นสำหรับวัสดุก่อสร้างBuilding Moisture Meter

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

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.

Attention: All the characteristic curves of the wood types of this column and the adjoining one are stored inside the building moisture meter. 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 building moisture meter you will be able to easily determine humid zones in floors, walls, etc for a relative measurement in wet or weak areas.
