ADVICE AND PRACTICES FOR A CORRECT EVALUATION OF WOOD MOISTURE IN CONSTRUCTION SITES
Construction phases are always very delicate and deserve more attention in the case of wooden buildings.
Excessive construction times, inadequate storage of materials and their prolonged exposure to atmospheric agents could lead to serious critical situations.
The topic of greatest interest always concerns the rate of humidity accumulated by wood, in particular when it is decided to "close" the walls, floors or roofs, realizing counter-walls, flooring or other processes, which risk greatly reducing the drying of the wood, if these values are too high at the start.
It becomes, therefore, fundamental to have knowledge and awareness of the level of humidity of the wood of these structures, monitoring it over time.
Choosing the right moment to "close" the wooden parts is essential to secure the building and avoid subjecting the structure to long periods in the presence of excessive humidity, which could damage the wood in an irreparable way.
Our advice, gained in years of experience in the installation of MyMeter Monitoring Systems is to make precise measurements of humidity, mapping the structure and identifying the critical points where to make the measurements. A simple hygrometer for wood is sufficient to do this.
The objective is to choose the most appropriate moment to proceed to the closure, In function of the measured values.
The experience and the data of literature lead us to consider, in general, the following values of humidity as those to refer to in order to proceed in making the appropriate decisions:
Humidity less than 18% is an appropriate value for the closure
Humidity between 18 and 20% is an acceptable value, but to be monitored
Humidity above 20% is an unacceptable value for the closure

The suggestions also depend on other factors, which have not been taken into account at this time, but serve in general to have a line to refer to.
POINT READING VIA THE MYMETER SYSTEM DURING INSTALLATION
The MyMeter permanent monitoring system was born with the idea of preventing and preserving over time the structural parts of the building, from prolonged contact with water or humidity, throughout the life of the building.
In case the MyMeter System has been installed in the building, even if not yet active (no current, incomplete sensor/ control unit wiring), you can use the moisture measurement probes of the MyMeter System already installed, also for the only punctual reading with a hygrogretro for wood.
To do this you need to use a hygrometer adapter, already present in every MyMeter installation kit. Through this adapter it is possible, at any time, to connect the probes already inserted in the wood, to the hygrometer in your possession.
Remember that each MySense sensor manages two reading probes, which can also be placed several meters from each other.
To allow the recording of the measured humidity values, we have prepared a special table to keep track of the evolution of the humidity concentrations detected over time.
Below are the instructions to complete the table and make the connection between probes, adapter and hygrometer.
