Upgrade your old boat’s electrical system monitoring device to our M2 OLED AC Voltmeter. This Voltmeter accurately monitors the voltage of your AC system and can measure up to 2 independent circuits or 1 double phase circuit with ± 1.0% accuracy.

Designed with MOSFET relay technology that has the advantages of higher commutation speed and greater efficiency during operation at low voltages.

OLED display is daylight readable with an auto-dimming feature so you don’t get blinded during night time use.

Ip66 rated as “dust tight” and protected against heavy seas or powerful jets of water with various mounting options.

A DC version of our M2 OLED Voltmeter is also available for DC application.
