Blue Sea 1842 M2 OLED Digital Bilge Meter

The Blue Sea 1842 M2 OLED Digital Bilge Meter tracks up to 4 bilge pumps, giving you visibility into how often they're cycling and for how long. It is designed for boaters who want an early warning if a bilge pump is running more than it should, which often signals a leak.

The included MOSFET external circuit relay can trigger an alarm or external circuit based on run time per hour, cycles in the last 24 hours, or average cycle count, catching problems before they become emergencies. Note that the bilge float switch itself is not included. Browse more options in our panels, switches, and circuit breakers category.
