Maretron EMS100 Engine Monitor

Maretron NMEA 2000 Marine Electronics
EMS100 Engine Monitor

Maretron’s EMS100 plugs directly into engine wiring harnesses and converts analog signals such as water temperature and oil pressure to the new marine digital interface (NMEA 2000®). Critical engine data is then distributed throughout the vessel over a single cable where it can be monitored by any NMEA 2000® compatible display.

The EMS100 is compatible with existing instrument panels and key switches so you don’t need to remove them while upgrading to newer digital technology. For new installations, the EMS100 and a compatible NMEA 2000® display can replace the traditional analog instrument panel.
