You can measure the voltage drop across by measuring the voltage required to make a current flow in the forward biased direction.
If you measure the current as a function of voltage for a forward bias you get something like:

The knee voltage ($0.65 - 0.7$V in this case) is a measurement of the potential across the junction.
