FME Humidity Detector for building materials
to measure absolute humidity of wood. Automatic temperature compensation

The FME humidity detector can determine with high accuracy absolute humidity in wood, building materials and even in paper. This humidity detector comes with a connection for external sensors which can be either introduced in the material or placed on it. Its additional external temperature sensor allows for an automatic temperature compensation. 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 FME humidity detector for building materials is the ideal tool for the control of building materials such as: pavement, cement, gypsum, mortar, concrete and diverse wood types (it depends on the sensor). The detector is also recommended for technicians and builders to measure humidity in situ and to determine humidity in walls, floors, ... The detector has characteristic curves for different materials which can be recovered at any time.
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 FME humidity detector can be used for all kind of jobs.

Characteristic 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, building materials and paper types (500 values are stored in the humidity detector to be recovered at any time). We can also send another list with more information.

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.


Grain direction of board:
The result will not be affected if measurement is taken either in the grain direction or against grain direction. 

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.
