It looks like the meter could be a cost effective substitute for the formulae. I wonder how an inductance meter might be of value with the transformers and chokes in our restoration and repair?

Once every month or two, I have some reason to measure a choke. I used a GR or HP bridge, but more recently bought a Wavetek hand-held meter at the flea market. They're not much help for transformers, which don't have a defined inductance.

I once used Wavetek equipment in bench work, but most of the equipment required both hands and a strong back. I hope the portable unit performs to Wavetek's good reputation.

The meter shown by the OP is ok for for work in the audio through low HF region, but as you go higher inductors get pretty small and the meter shown becomes useless.

There are several ways to measure small value inductors and capacitors.   You can use a Boonton 250 reactance meter, or a model 190 or model 260 "Q" meter, you can also use a grid dip meter and calculate similarly to the earlier reference.   There are also several manual and automatic RLC bridges built by General Radio and HP in years gone by that can be used
These old pieces of TE have plenty of accuracy, and are actually fairly quick and easy to use, once you're familiar with them.

I have one of these

sencore lc53

I use it mainly for caps. I rarely have a need to check for inductors.
