Abstract:
1. A humidity probe for positioning in a hole in a solid for estimating the moisture content of the solid from determination of the relative humidity of the hole, the probe comprising: a housing having a head portion and a tail portion; an electronics module disposed within the housing; a display associated with the head portion and in communication with the electronics module; the tail portion having an inner chamber and an exterior surface with aperture therethrough; at least one rib positioned around the perimeter of the housing for engaging a surface defining a perimeter of a hole in a solid; a relative humidity sensor disposed within the tail portion of the housing proximate the aperture, the relative humidity sensor in operative communication with the electronics module and with an exterior environment, wherein the relative humidity sensor is positioned such that substantially no dead volume exists in the tail portion between the sensor and a volume defined by the solid, the rib, and the external surface of tail portion.
