Product Description

Panel Mount M2 AC Multimeter

Measure your boats essential DC electrical system parameters in one compact device with our M2 OLED AC Multimeter.

Our M2 OLED AC Multimeter accurately measure and monitor AC amperage, voltage, and Hz. (measures independent 2 voltages and 2 current circuits, or 1 double phase circuit)

It includes one 150A AC Current Transformer with a maximum 300A AC total amperage.

Designed with adjustable internal 92dB alarm for High Current, High/Low Voltage.

Our Multimeter has the M2 monitor that included MOSFET External Circuit Relay (ECR) which can be used to control external circuits based on any value measured by the M2.

Bright Organic LED display is easy to read with an auto-dimming feature for night time use.

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

An AC version of our  M2 OLED Multimeter  is also available for DC system use.
