Abstract The precise measurement of electrical resistivity of Karma alloy in the temperature range from 70 to 440 K was conducted in the further development of an adiabatic calorimeter. The minimum and maximum resistivity was obtained as 133.340 and 133.906 μΩcm respectively. A maximum near 340 K on the plot of temperature dependence upon resistivity is an anomaly that seems to be neceessary for any further study.
