The measurement of moisture in building fabrics has been of interest for many years due to thepotentially devastating consequences of moisture problems within buildings. A range of potentialtechniques are available with which to measure the moisture content of building fabrics in-situ and thispaper focuses on one particular technique, the thermal dual-probe. Note that this method is distinctfrom the single probe technique. Essentially, a short pulse of electrical energy is applied to a wirewithin the heating needle.
