The M2 OLED Digital Monitors measure essential electrical system parameters with adjustable alarms and an auto-dimming display in a compact enclosure. The gasket creates a waterproof seal on the unit face. Monitors AC Volts for two independent circuits or one double phase circuit. The M2 Monitors include a MOSFET External Circuit Relay (ECR) which can be used to control external circuits based on any value measured by the M2.
