Blue Sea Systems 1842 M2 OLED Digital Bilge Monitor

The Blue Sea Systems 1842 M2 OLED Digital Bilge Monitor provides comprehensive monitoring of up to four bilge pumps with an easy-to-read organic LED display and customizable alarm functions. This advanced monitoring system tracks bilge pump activity, runtime hours, and cycle frequency to help detect potential water intrusion issues before they become serious problems.

Key Features:

• Auto-dimming bright OLED display (55mm x 28mm) for excellent visibility in all lighting conditions
• Monitors up to 4 separate bilge pump circuits simultaneously
• 80dB audible alarm alerts you to excessive pump activity
• Integrated 500mA isolated MOSFET relay for controlling external circuits based on monitored values
• Adjustable alarm thresholds for run time per hour, cycles per 24 hours, and average cycles
• Wide input voltage range: 7-70V DC for compatibility with various electrical systems
• Low power consumption: 0.3W-1.0W

The M2 Monitor's External Circuit Relay (ECR) capability allows you to trigger external devices or alarms based on bilge pump activity, providing an additional layer of safety and automation. Installation requires bilge float switches (sold separately) for each monitored pump circuit.
