This article describes techniques used to validate the performance of the microK thermometry instrument, which
was designed for use in secondary temperature calibration and high accuracy temperature measurement
applications (to <0.4mK uncertainty). The microK is the first precision thermometer that can work with both
resistance thermometers and thermocouples and provides sub mK uncertainties with SPRTs and mK
uncertainties with thermocouples. With a resistance ratio accuracy of 0.4ppm and voltage accuracy of 0.25
