An Improved Welding Jig for Peltier Thermocouple Psychrometers

Abstract An improved welding jig is described for making fine wire thermocouples for use in Peltier thermocouple psychrometers. Procedures are described for producing thermocouples with little or no twisted wire at the junction. Thermocouples made with the jig were found to produce higher outputs at low water potential than commercially available thermocouples.
