An improved instrument for determining water potential by measuring dewpoint depression has been developed. Theoretical considerations show the instrument to have a sensitivity of 0.75 uV bar -~ and a change in sensitivity with temperature of 0.45% ยฐC-~. Without compensation for changes in Peltier c
