Product Description

Panel Mount M2 AC Voltmeter

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.
