Blue Seas M2 OLED Digital Voltmeters

Blue Seas M2 OLED Digital Voltmeters measure Voltage for either AC or DC systems.

BS-1833 monitors DC Voltage of up to four battery banks; where BS-1837 monitors the Voltage of your AC system (measuring 2 independent circuits - 120/240V - or 1 double phase circuit.)

The M2 Monitor includes a MOSFET External Circuit Relay which can be used to control external circuits based on any value measured by the M2.
