Vessel Systems Monitor VSM 422

The Vessel Systems Monitor VSM 422 performs comprehensive

monitoring of four boat systems in one compact meter, saving

space and money.

By monitoring DC (including battery state of charge), AC, tanks, and

bilge pump, the VSM 422 alerts boaters to problems before they

become emergencies.

The ability to monitor state of charge is critical to safe boating. By using a

complex calculation of voltage, amperage, and amp-hours remaining, the

VSM 422 is able to provide accurate and timely information about state of

charge on the house battery to help boaters know when it's time to recharge.

The VSM 422 also monitors temperature on the primary battery with the

included Battery Temperature Sensor.

AC monitoring includes voltage, amperage, wattage, and frequency.

Tank monitoring for up to three tanks includes alarm functions for high and

low levels, and bilge pump monitoring includes pump active, cycle count,

and duration.

With its user-friendly interface, intuitive display modes, and versatile case

design, the Vessel Systems Monitor VSM 422 is an excellent replacement for

four separate system monitors.
