ABSTRACT:
Apparatuses and methods for continuously recording the relative humidity and/or the vapor pressure of a gaseous component of a material within a gaseous mixture utilizing a relative humidity sensor having a curvature changeable with respect to changes in the relative humidity of said gaseous mixture alone or coupled to a saturation vapor pressure sensor having a linear dimension changeable with respect to changes in the saturation vapor pressure of the material and a means to contrast the linear dimension of saturation vapor pressure sensor to the span of the relative humidity sensor, the resultant value representing the actual vapor pressure of said material.
