Description
The Blue Sea Systems M2 DC Ammeter (1832) is a high-precision, panel-mounted monitor designed to provide real-time current measurements for DC electrical systems. With a crisp, daylight-readable OLED display, the M2 Ammeter clearly shows amperage readings and additional system data, making it ideal for boats, RVs, and off-grid power systems.
It supports monitoring for a single DC current source (up to 500A) via a compatible shunt (included), and features programmable alarms, data logging, and configurable display options. The M2 Series is known for its simple installation, intuitive interface, and sleek modern design.
