Description
Following is a sample of the information contained on this CD: INTRODUCTION 1. Field of the Invention The invention relates to a moisture meter of the type for surveying applications in which the meter is hand-held and, in use, is held so that a sensor attached to it is in contact with the material being surveyed. 2. Prior Art Discussion While such meters are generally quite accurate, they suffer from a lack of versatility because they are configured for only one type of material and calibration for variations of material is difficult for the user. Also, it is necessary for the user to note down on paper readings from the dial, which is time-consuming and difficult in some environments such as attic spaces. Objects of the Invention It is therefore an object of the invention to provide a moisture meter which may be used with a wide range of different materials. Another object is to provide for capture of moisture information in a more simple manner. A further object is to provide for more accurate determination of moisture content. SUMMARY OF THE INVENTION According to the invention there is provided a moisture meter comprising a hand-held housing supporting a moisture sensor of the type for contact with a material being surveyed, an output interface, and a controller comprising means for determining moisture content data according to signals from a moisture sensor drive circuit and for outputting said data at the output interface, wherein: the meter further comprises a user input interface, the controller comprises means for selecting stored material parameter values in response to user inputs, and the controller comprises means for performing data processing with said selected parameter values to determine moisture content of a material in contact with the moisture sensor. In one embodiment, the controller comprises an analogue to digital converter for conversion of analogue signals from the moisture sensor drive circuit. In one
