Sea-Dog Round OLED DC Amp Meter, 0 to 100 Amp

The Sea-Dog Round OLED DC Amp Meter provides a clear 0-100 amp readout for monitoring current flow in marine electrical systems. Its bright OLED display is designed for daylight readability and high contrast, with a wide viewing angle that remains visible even when wearing polarized sunglasses.

The meter is built to handle constant vibration and wet or dusty environments, making it suitable for helm panels, electrical cabinets, and other onboard monitoring locations. Reverse-polarity protection helps protect the electronics during installation, and the compact round housing is the same general size as a standard 12V receptacle for flexible mounting options.

Injection-molded nylon construction adds durability, while the IP66 rating provides protection against water ingress. A 100A/50mV shunt is included for current measurement. For boats that need a compact dedicated DC ammeter with a highly readable display, this Sea-Dog meter provides practical real-time monitoring. Take a look through our marine electrical meters.
