Measurement of relative humidity has been neglected in most biological field studies partly because of difficulty of accurate measurement. This paper reviews classical relative humidity instruments and modern electrical transducers. Accuracies and operational problems are compared. Finally several approaches to construction of electronic humidity measuring instruments are presented together with a schematic of one circuit which has been field-tested.
