You can buy a DMM that measures inductance. I have a wavetech meterman model that was under $100.00 that does capacitance from many micro farads to pico farads, inductance from henrys to micro henrys, frequency to 10 Mhz, plus all the other usual DMM stuff.
I also ran into problems with some chokes, on a green body the colors don't show well, and the DMM told me what was a choke and what value it was. Its also great to measure vari cap settings in homebrew stuff, and to identify what value those big chokes are that I use for the big tube transmitters, the inductance of coils used in the homebrew receivers, even the range of slug tuned coils.... Well worth the investment is you do a lot of electronics...
