Yes, but an almost universal drawback to digital panel meters is that they
cannot be used to measure a voltage that has anything in common with the
power supply used to power the meter. Bear that in mind and be prepared to
provide independent power to the meter.
I saw a meter that could measure its own voltage. I cant remeber where but a
google search should find it.

Try to find an old Ethernet ISA card with BNC connection.
On the card you wil find a little (about 1 inch) black box
like an IC but fatter.
This is a power supply isolator. Using it, you can make a
separate ground for the measured voltage and the power to
the meter.

Well if you went to this website you would find one that does measure it's
own voltage for 15.00 or less
