43. Temperature Scales Using Radiation Thermometers Calibratied From Absolute Irradiance and Radiance Responsivity
Published: Date unknown
Authors: Howard W Yoon, David W Allen, Charles E Gibson, Robert D. Saunders, Bettye C Johnson, Steven W Brown, Keith R Lykke
Abstract: In the International Temperature Scale of 1990 (ITS-90), temperatures above the freezing temperature of silver are defined with radiation thermometers calibrated using spectral radiance ratios to one of the silver-, gold- or copper-freezing temperatu ...

44. Thermodynamic-Temperature Determinations of the Ag and Au Freezing Temperatures Using a Detector-Based Radiation Thermometer
Published: Date unknown
Authors: Howard W Yoon, David W Allen, Charles E Gibson, Maritoni Abatayo Litorja, Robert D. Saunders, Steven W Brown, George P Eppeldauer, Keith R Lykke
Abstract: We describe the development of a radiation thermometer calibrated for spectral radiance responsivity using cryogenic, electrical-substitution radiometry to determine the thermodynamic temperatures of the Ag- and Au-freezing temperatures. The absolut ...
