The Role of High-purity Noble Metals in Precision Thermometry



Dean C. Ripple, Gregory F. Strouse, Weston L. Tew


A variety of alternate calibration schemes which approximate the ITS-90 are possible when using high-purity noble metals. The high purity of the sensor materials allows the use of correlations that exist between the measured properties at fixed point temperatures. The data from NIST Standard Reference Materials 1749 and 1750 serve to illustrate the degree to which such schemes may succeed using comparable material. The result is a variable cost versus accuracy trade-off in calibration procedures that can be customized to the measurement needs of various industry sectors.
