Development of the Sealed-Type Triple-Point-of-Argon Cell for Long-Stem SPRT Calibration at KRISS

A system was fabricated to realize the triple point of argon for the calibration of long-stem standard platinum resistance thermometers. A cryostat was constructed so that the temperature could be controlled quasi-adiabatically, and the melting was realized using the continuous-heating method. The c...

Zusammenfassung:A system was fabricated to realize the triple point of argon for the calibration of long-stem standard platinum resistance thermometers. A cryostat was constructed so that the temperature could be controlled quasi-adiabatically, and the melting was realized using the continuous-heating method. The combined uncertainty of the realization of the triple point of argon for a confidence level of 95% was 0.6 mK.
