Abstrakt: In situ testing of material water uptake represents one of very basic and indispensable techniques in the conservation practice aiming different purposes. Water uptake of porous building materials used on historical constructions significantly correlated to some other materials characteristics. Capillary properties of porous materials can be measured by means of Karsten tube and modified tools of methods. A pilot prototype of one of them has been developed and tested in ITAM AS CR for measuring water absorption under low pressure. The device has output connector for linking to a computer and reading the stored data. The device was tested in laboratory as well as in situ for a basic performance. The acquired data were evaluated using software specially writen for this purpose in MatLab.
