Blue Sea Systems M2 OLED AC Multimeter — Panel-Mount Shore Power Monitor
Monitor your vessel’s AC shore power system at a glance with the Blue Sea Systems M2 OLED AC Multimeter. This compact, panel-mount monitor displays AC voltage, current (amperage), frequency, and power factor on a bright, high-contrast OLED screen — giving you a complete picture of your shore power connection quality and load in real time.
Blue Sea Systems is the industry standard for marine electrical monitoring and distribution equipment. The M2 series is designed specifically for marine panel installations, with a sealed, waterproof-rated housing, a compact footprint that fits standard panel cutouts, and an OLED display that remains readable in direct sunlight and low-light conditions alike.

Best Use Case
Best suited for installation in the AC electrical panel of powerboats, sailboats, and motor yachts connected to shore power. The M2 OLED AC Multimeter allows you to monitor shore power quality (voltage and frequency), track your vessel’s AC load in real time, and identify potential issues such as low voltage, overloading, or poor power factor before they cause damage to onboard equipment. Pair with the M2 OLED DC SOC for complete AC and DC electrical monitoring at the panel. Follow Blue Sea Systems’ installation guide for correct wiring and panel cutout dimensions.
