Blue Sea 8248 DC Digital Multimeter with Alarm

The Blue Sea 8248 DC Digital Multimeter with Alarm displays both amperage and voltage on one splashproof panel meter with a 500 amp shunt included. It is designed for boaters who want precise DC current and voltage monitoring across a wide range of battery system voltages.

High and low voltage trigger both audio and visual alarms, and voltage reads out in precise 0.01-volt increments. Three levels of display brightness and a programmable sleep mode help manage power draw, though note the standard meter reads negative-side circuits only — a Shunt Shifter is needed for positive-side installations like alternators.
