12V – 24Vdc
Standard hole size
Mini OLED Voltmeter
Panel Mount Voltmeter
Our daylight readable voltmeter mounts in a standard 1 1/8″ 12V / USB hole. This Blue Sea 1733 voltmeter display is a crisp and clear digital readout visible during the day, and not too bright at night using OLED technology.
Extremely simply to install with only two terminals… a positive and a negative.
Accurate voltage measurement with 10mV (0.01 volt) accuracy. This little guy is a super easy upgrade to the old cigarette lighter socket you never use.
Keeping an eye on battery voltage is the easiest way to monitor the state of charge of your battery.
