Maintenance and Validation of Liquid-in-Glass Thermometers

Christina D. Cross, Dean C. Ripple, Gregory F. Strouse
Liquid-in-glass thermometers are pervasive in use throughout industry and provide a convenient method for measuring temperature over for a broad range of

Acoustic Thermometry Results From 271 K to 552 K

Dean C. Ripple, Gregory F. Strouse, Michael R. Moldover
The NIST Acoustic Thermometer determines the thermodynamic temperature from measurements of ratios of the speed of sound of argon in a spherical cavity. We

NIST Realization of the ITS-90 Gallium Fixed Point

Gregory F. Strouse
As defined by the International Temperature Scale of 1990 (ITS-90), the gallium melting-point cell (29.7646 C) is used in the calibration of standard platinum

Stabilization of SPRTs for ITS-90 Calibrations

Dennis B. Minor, Gregory F. Strouse
At the National Institute of Standards and Technology (NIST), the ITS-90 calibration of standard platinum resistance thermometers (SPRTs) is performed in the

Techniques for Primary Acoustic Thermometry to 800 K

Dean C. Ripple, Dana R. Defibaugh, Michael R. Moldover, Gregory F. Strouse
The NIST Primary Acoustic Thermometer will measure the difference between the International TemperatureScale of 1990 and the Kelvin Thermodynamic Scale
