ABSTRACT:
Method of monitoring and indicating the concentration of vapor components at a phase interface comprising sampling vapor at the vapor source phase interface, comparing the vapor concentration in the sample with a standard, and indicating the concentration of the vapor relative to the standard. A monitoring device is disclosed which comprises a sensing means and means for responsively coupling the sensing means to the vapor source phase to be monitored so that a representative vapor sample is presented to the sensing means. The method and device disclosed herein can be advantageously used to monitor volatile components, especially moisture, available to potted plants.
