Temperature measurement capability was inter-compared using the transfer standard platinum resistance thermometers(SPRT) among four laboratories of KRISS. The transfer SPRTs were primarily calibrated at the triple point of water and Ga melting point, then used at inter-comparison experiment. Temperature difference of calibration value between temperature laboratory and length laboratory at $20^{circ}C$ was -0.7 mK and +2.4 mK at density laboratory. Temperature measured near $20^{circ}C$, $25^{circ}C$ and $30^{circ}C$ at fluid flow laboratory was deviated by $34.2{sim}80.4;mK$ from the calibration values of the transfer SPRT. Ga melting points was inter-compared among three laboratories, and the difference of Ga melting points against the standard Ga melting point of temperature laboratory were $0.03{sim}0.54;mK$ at length laboratory and 0.02 mK at density laboratory.
