An antique but good device for measuring inductance (there is a
capacitance measuring version too) was the Rhode and Schwarz LARU - a
later version was the LART. I am not sure if there is a more modern
version.....
It works on the basis of a capacitor connected to the unknown and a
device to check the self resonant frequency - it is rather like an
accurate GDO. Obviously the capacitance version works by checking with
a known inductor......
I would imagine that a similar device should be easy to make...
