A criticism is made of the methods available for selecting metallic wires to be used in the construction of thermoelectric thermometers. Methods are described which increase the reliability, rapidity and convenience of selection tests. Techniques are introduced for the construction of more homogeneous thermocouples and multi-junction thermoelements from a test cable of the wire under consideration, thus extending the range of application of the thermoelement to the precise measurement of larger temperature differences and the validity of its calibrations to more varied conditions. Examples are given of the application of these procedures to the construction of low temperature copper/constantan thermometers.
