Get the new fidbox® app NOW! You probably know that hardwood floors are very sensitive. But do you know if your rooms are too hot/cold so it damages your floors? Do you know if the humidity in your rooms is too high/low? Here's the solution for your mobile phone: the new fidbox® app. Connected to your fidbox® you are able to read out the temperature and humidity the fidbox® has measured and take instant action to prevent your dearly bought floors from getting damaged. ----------------------------------------------- What is the fidbox? The fidbox® is a monitor for temperature (°C) and relative humidity (%) as well as a data log for long-term data recording all in one, which is concealed in the hardwood flooring itself. The data stored therein can be read at any time by wireless transmission and allows the determination of the degree of moisture in the screed and in the hardwood flooring by vertical measurements. This information is not only pertaining to the indoor environment, but is especially important in the event of damage as it provides understandable facts.
