Can you estimate this with an ordinary multimeter? If so, what sort of
figures would indicate a moisture level below 20%?

I assume meters made for the purpose just measure resistance across a fixed
distance, but I could be wrong.

In short No!

A DMM cannot even measure damp accurately, there are too many
variables.

Density is your best bet.

weigh a fresh log, measure it, plane it or cut it to increase the
surface area, stick it in a microwave on defrost for a few hours,
weighing it until there is no significant reduction in reading.

Now you can do things by the ton if you wish using a winch and an
FIBC, or if you want to get really technical go for the ureka thing on
bathnight.

Having got your start weight, just bide your time and weigh again in
about two years if it's logs for a fire.

Tip! If married the FIBC approach is desireable.
If Married and bath night is a "social occasion" then the FIBC
approach is mandatory
