Abstract
The present invention has to do with a method and system for a high precision electronic psychrometer operable at low temperatures and high humidity environments. The electronic psychrometer includes thermistors for measuring wet and dry bulb temperatures and a wicked cage surrounding one of the thermistors. The wicking action of the wicked cage is controlled by an evaporation controller in conjunction with the wick's physical parameters. The electronic psychrometer determines relative humidity and provides a readout display and/or a control signal.
