  • Abstract
    A fully automatic precision thermometer using the NQR absorption of KCIO3 has been developed. The temperature absorption signal is automatically “searched.” The search frequency is locked to the center of the absorption signal and is converted to a temperature scale. Temperature readings from 77 to 374 K, with accuracy, reproducibility, and stability confirmed to ±1 mK at the triple point of water have been obtained.
