Abstract

An automatic multichannel selector system and a simple, inexpensive amplifier are described for recording the output from Richards and Ogata droplet thermocouple psychrometers or Spanner thermocouple psychrometers. Agreement was good between the water potentials of wheat leaves measured by the Richards and Ogata psychrometers and a pressure chamber.[12:221.212].
