Absolute Radiation Thermometer Is Under Construction in NIM


NIM is developing the absolute radiation thermometer to determinate the temperature of metal-carbon eutectic points which are the candidates of the new fixed points in the high temperature. The first round of thermodynamic temperature measurement of fixed points has been completed at NIM and compared with PTB. The difference of T measurement between PTB and NIM is within 0.2 K. Now NIM joins the T value determination of the HTFPs and will start the measurement in 2013.
