Blue Sea 8239 AC Digital Frequency Meter

The Blue Sea 8239 AC Digital Frequency Meter displays AC frequency from 40 to 90 hertz on a splashproof panel meter. It is designed for boaters who want a dedicated frequency check to catch generator or inverter problems before they damage sensitive electronics.

Three levels of display brightness let you match the meter to cabin lighting or bright sun, and the splashproof front holds up to the occasional spray at the helm. A dedicated frequency meter reads faster and clearer than hunting for the value on a multi-function display. Browse more options in our panels, switches, and circuit breakers category.
