Measure amps in 12-, 24- or 48-volt systems with this high-quality LCD digital meter. The surface mount 3" x 2" x 1" enclosure can be attached to surfaces with two screws. Terminal strip on the back of the meter accepts 14 to 22 AWG wire.

This amp meter comes with a 100A/100mV shunt to measure up to 100 amps with 0.1 amp resolution. Current draw is only 20mA. Amp meters are bi-directional, so they can be used to read loads, showing negative numbers, or to read charging sources, displaying positive numbers.

Amp meter requires 4-conductor wire. Use 22 gauge or larger for up to 50 feet. Use 18 gauge for up to 150 feet.
