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

Characteristic material curves / Temperature compensation
With the Concrete Moisture Meter FMC for building materials it is possible to determine with high accuracy the real moisture content by introducing the corresponding characteristic value of every material (for the characteristic curve of the stored material) in the Concrete Moisture Meter. 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 its electric power capacity (and also its humidity), a temperature compensation has to be carried out. It can be adjusted in the detector with 1°C intervals (manual compensation).

To take into account:
Measuring values will be higher in chips or knots. On the contrary, 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 should measure near the area that is going to be measured and use the mean value.
Due to the inhomogeneous composition of wood, oscillations in gross density can appear while measuring the same wood type so you will have to take diverse humidity measurements. The overall result will be the mean value calculated by the Concrete Moisture Meter.
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.
