The fidbox from Humidity Devices, provides you with reliable information about the environmental conditions of your hardwood flooring. The fidbox is installed under the flooring and measures from below the temperature and humidity fluctuation in the floor construction and the subfloor. The saved data can be wirelessly read at any time from the fidbox without having to remove any of the flooring. It is the "Black Box" data recorder for the flooring industry.
