Blue Sea 1732200 Blue Mini OLED Waterproof Ammeter

The Blue Sea Systems 1732200 Blue Mini OLED Ammeter reads DC current from -100A to +100A at 0.1A resolution on a blue display.

Blue is the display color choice against the standard 1732, and on a helm it is about matching the other instruments rather than legibility. Mixed display colors across a dashboard look assembled over time, and most modern marine electronics run blue or white.

Electrically the two are identical: bidirectional reading, 0.1A resolution, 12V and 24V systems, and the same 1-1/8-inch mounting hole. That hole is the standard gauge cutout, so the meter fits where an existing instrument came out without new holes.

Current can be monitored from either the positive or negative side of the circuit, with reverse-polarity protection against an installation mistake. The waterproof display is daylight readable, it consumes very little operating power, and it tolerates higher short-duration current during cranking. Explore more marine electrical meters.
