Abstract High-precision measurements of the3He melting pressure versus temperature have been made from 500 μK to 25 mK using a60Co nuclear orientation primary thermometer and a Pt NMR susceptibility secondary thermometer. Temperatures for the fixed points on the melting curve are: the superfluid A transition TA = 2.505 mK, the A-B transition TAB = 1.948 mK, and the solid ordering temperature tn = 0.934 mK. These fixed points and a functional form for P(T) constitute a convenient temperature scale, based on a primary thermometer, usable to well below 1 mK.
