Blue Sea 8240 DC Analog Voltmeter - 2-3/4" Face, 18-32 Volts DC [8240]

The Blue Sea Systems 8240 provides an analog view of system voltage across an 18–32V DC range. Its standard 2-3/4-inch face fits marine electrical panels and keeps voltage information visible at a glance. An internal shunt supports the meter’s voltage measurement, while the backlit face improves readability in low-light conditions. Separate backlight connections support 12V or 24V DC illumination circuits.

• 18–32V DC measurement range: Monitors voltage in compatible 24V marine and vehicle electrical systems.
• 2-3/4-inch face: Provides a standard-size analog display for clear panel-mounted viewing.
• Backlit meter face: Helps keep the scale readable during nighttime or low-light operation.
• Internal shunt: Supports the meter’s voltage-sensing function without requiring a separate external shunt.
• Low meter draw: Uses approximately 1 mA at full scale, helping limit monitoring-system power consumption.

• What voltage range does the 8240 measure?
  The meter measures 18–32V DC, making it suitable for compatible 24V electrical systems.
• What is the face size?
  The analog meter has a 2-3/4-inch (69.85 mm) face.
• Is the display backlit?
  Yes. The meter face is backlit, with separate connections for 12V or 24V DC backlight circuits.
• How is the meter connected?
  The 8240 uses a four-wire connection for meter operation and backlighting.
• Where can it be used?
  It is intended for monitoring compatible marine, boating, and other 18–32V DC electrical systems.
