Blue Sea 1838 M2 OLED AC Digital Multimeter

The Blue Sea 1838 M2 AC Multimeter monitors AC amps, volts, and hertz on one bright display, measuring 2 voltages and 2 circuits at once. It is designed for boaters who want AC current, voltage, and frequency monitoring in a single compact meter instead of three separate gauges.

An auto-dimming, bright OLED display stays easy to read in any light, and a 92dB alarm warns you of high or low current, frequency, or voltage before it becomes a problem. Programmable current transformer ratios let you match the meter to your specific system, and an isolated MOSFET relay is built in for automated control.
