Blue Sea 8244 AC Analog Micro Voltmeter - 2" Face, 0-150 Volts AC

The Blue Sea 8244 AC Analog Micro Voltmeter is a compact 2-inch face voltmeter designed for monitoring alternating current (AC) voltage in marine electrical systems. Built by Blue Sea Systems—a manufacturer with deep expertise in marine power distribution—this meter provides reliable voltage monitoring on vessels where AC power availability and stability are critical to safe operation. The simple 2-wire connection design and backlit meter face make this instrument practical for both routine diagnostics and real-time monitoring in engine rooms, galley areas, and auxiliary power installations.

The voltmeter reads AC voltage in a 0-150 volt range with dial markings at 5-volt increments, allowing quick visual assessment of shore power and onboard AC generator output. The meter draws power from the same circuit it monitors, eliminating the need for a separate power source and simplifying installation. The backlit dial face improves readability in low-light engine room conditions, a practical consideration for vessels operating at night or in enclosed spaces. At just 0.1 pounds and measuring 3 x 3 x 7 inches, the compact footprint fits easily into standard panel cutouts without consuming valuable dashboard real estate.

This AC voltmeter is essential for boaters who rely on onboard AC power systems—whether from a marine generator, shore power connection, or inverter setup. Weekend fishermen using cabin AC systems and serious offshore anglers with sophisticated electrical installations alike benefit from immediate voltage feedback that warns of potential charging issues, generator malfunction, or shore power delivery problems before they damage sensitive electronics or leave crew without essential power. The Blue Sea 8244 integrates into existing electrical panels or serves as an upgrade to aging analog meters, offering the straightforward reliability analog instruments are known for without the complexity of digital readouts.
