The VNIIFTRI magnetic temperature scale is compared with the provisional low-temperature scale (PLTS-2000), based on the melting pressure of He-3, in the 0.37–0.56 K range. The magnetic temperature scale is reproduced from the readings of a rhodium-iron alloy resistance thermometer. The disagreement between the scales does not exceed 0.23 mK.
