Method and measuring system for checking the humidity absorption and emission of construction elements

摘要

The method involves determining a water vapour pressure at a measuring point inside a construction unit (1) e.g. heat insulator. Another water vapour pressure is determined at another measuring point outside the construction unit. The ratio of the water vapour pressures inside and outside the construction unit is monitored as the function of time. The determination of the water vapour pressures are effected by recording physical measurement values by measuring devices (8a, 8b), and the measurement values are transmitted to a central processing unit (15) by a cable connection and/or radio link. An independent claim is also included for a measuring system for checking the humidity absorption and delivery characteristics of a construction unit e.g. heat insulator.
