FMC Humidity detector for building materials
to measure absolute humidity

The FMC humidity detector can measure accurately absolute humidity in diverse building materials. To detect humidity, the FMC humidity detector has a connection for external sensors which can be either introduced inside the building material or  placed on it. This detector corrects the humidity value measured in real percentages in relation to the selected material and the temperature (according to dry / absolute humidity). The humidity detector can be used both in input controls and to measure in situ: concrete, asbestos, cement, plaster, lime-stone, pavement, bricks, ... The FMC humidity detector has some characteristic curves stored to measure different materials. These curves can be displayed by means of the keyboard.
It is important to choose a humidity probe that best suits the material is going to be measured. There are different models for different applications and materials. The FMC humidity detector can be used for all kind of jobs.

Characteristic material curves / Temperature compensation

With the FMC humidity detector of building materials it is possible to determine with high accuracy the real moisture content by introducing in the detector the corresponding characteristic value of every material (for the characteristic curve of the stored material). Some charts with more than 500 characteristic values for wood, building materials and paper will be included in the delivery.

Temperature must be taken into consideration. As the temperature of the material influences on its electric power capacity (and also humidity), a temperature compensation has to be carried out. It can be adjusted in the detector with 1°C intervals (compensation by hand).

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.

To take into account:
Measuring values will be higher in chips or knots. On the contrary, if measurements are taken on breaks, 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 is going to be measured and use the mean value.


Measurement accuracy:
Due to the inhomogeneous composition of wood, gross density oscillations can be produced at measuring the same wood type so you will have to take diverse humidity measurements. The result will be the mean value calculated by the detector

Humidity probes / measurement sensors:
Here you will see a wide range of probes which can be adapted to different measuring instruments. You will be able to choose the probe that best suits your needs.
