Wall-mounted recessed sensor measuring relative humidity and temperature for plastered flush-mounting boxes or installation in hollow walls with high-quality, inconspicuous stainless steel design. Especially for museums and exhibition rooms, where measurement accuracy and almost invisible sensors have to be installed due to aesthetics. The precise measurement serves for a comfortable room climate and to avoid mold.
