Is this amp meter for DC?

It can measure and power itself from 7-32V. If you want to measure anything from 32-120V the thing needs to be powered separately. power supply to the device needs to be somewhere from 7V to 32V. That's my guess at least
 
Oh ok then, but what about the dc/ac? can it measure dc with a clamp meter? it says up to 500A so I'm guessing it's ac?
 
Yes. Pretty sure it has to be true rms meter . I use Southwire meters. The true sine d.c. meter I have only reads to 40 amps .

Although that does run the wire through a "clamp". Can you message the seller?
Looks like has it for 35.00 looking at other products he sells.
 
I'd assume it measures DC Amps, as it's sold as a battery monitor. There appears to be 2 voltage ranges, 7-32V or 12-120V, maybe there are 2 different models of the meter and you need to specify on ordering, or 2 input terminals you can connect to depending on application.

AFAIK DC "Clamp" meters use a hall effect sensor to measure current, I have a Fluke one that does this and it seems pretty accurate, but probably not as much so as a proper shunt.
