Blue Sea Systems DC Analog Voltmeter 8-16V

The Blue Sea Systems DC Analog Voltmeter gives a classic dial display of battery voltage across the 8-16V range typical of a 12V DC system — a simple, reliable way to keep an eye on state of charge and catch a charging problem before it leaves a battery dangerously discharged at a critical moment.

Key features

• 8-16V DC display range
• Simple 2-wire connection
• Meter current of 1 milliampere at full scale — a negligible parasitic draw on the battery
• Accuracy within 2.5% of scale range
• Backlit face for visibility in low light

Because it draws only 1mA at full scale, this voltmeter has essentially no meaningful impact on a battery's charge even if left connected continuously, making it a practical always-on gauge at the helm rather than something that needs to be manually switched off to conserve battery power.

This is the classic, no-frills way to monitor a single 12V battery bank's voltage, well suited to a boat, RV, or vehicle that doesn't need multi-bank monitoring or digital precision — just a quick, reliable glance at whether the battery is charging, resting at a healthy voltage, or slowly running low. Pair it with a DC Analog Ammeter (PN 8017) if current monitoring is also wanted at the same panel location.

This meter shares the same classic dial format as Blue Sea's other analog gauges, so it visually matches an existing panel of analog instruments rather than standing out as a mismatched digital add-on bolted on afterward without matching the rest of the instrumentation.
