The best choice of course would be to get a meter (e.g. DMM) that has
current measurement in the scale you need.

You can even do it with a simple resistor (e.g. 1K) and a voltmeter. It
all depends on the requirements, how much additional voltage drop due to
the measurement you can afford.

If you need a smaller voltage drop, you can use a smaller resistor and
build a small DC amplifier (one cheap IC and few resistors) or use an
off the shelf current sensing IC (Maxim, TI, etc).

These are some of the options. The best one depends on your
requirements.
