The 1850 M2 Vessel Systems Monitor is an essential tool for marine enthusiasts, offering comprehensive oversight of your boat's critical systems through its sleek organic LED display. Designed for reliability and ease of use, this monitor ensures that you stay informed about your vessel's vital parameters, enhancing safety and performance on the water.

Advanced DC System Monitoring

The VSM provides robust monitoring for up to two battery banks, ensuring your vessel's electrical system remains stable and efficient.

• Primary Battery Bank: Monitors DC voltage, state-of-charge, and current.
• Secondary Battery Bank: Monitors DC voltage.

Stay alerted with customizable alarms for high and low voltage, high current, and low battery levels, allowing you to address potential issues before they become critical.

Comprehensive AC System Monitoring

Maintain optimal performance of your vessel's AC systems with the VSM's detailed monitoring capabilities.

• Parameters Monitored: AC voltage, current, and frequency.
• Alarm Features: High and low voltage, high current, and high and low frequency alerts.

These features ensure that your AC systems operate within safe and efficient parameters, reducing the risk of electrical failures.

Flexible Bilge & Tank Monitoring

The VSM offers versatile monitoring options for both bilge pumps and fuel tanks, adaptable to your specific marine setup.

Bilge Monitoring

• Features: Pump activity status, cycle count in the last 24 hours, average cycles per day, and total cycles.
• Alarms: Set high alarms based on minutes of run time in the last hour and the number of cycle counts in the last 24 hours.

Tank Monitoring

• Display Options: Tank status in capacity (gallons or liters) or as a percentage of capacity.
• Customization: Auto-calibrate or program custom tank shapes.
• Alarms: High and low level alarms for all tanks to prevent overfilling or depletion.
