2-1/16 Fuel/Volt Gauge Elite Digital CB Series

The AutoMeter 2-1/16 Fuel/Volt Gauge Elite Digital CB Series (model 6709-CB) is a precision dual-function digital gauge designed to monitor fuel level and battery voltage simultaneously from a single compact instrument. The Cobalt Elite digital display combines modern electronic accuracy with the durability demanded in demanding operating environments, delivering real-time diagnostics critical for vehicle reliability assessment.

The 2-1/16-inch diameter black face accommodates standard gauge panel installations common to trucks, off-road vehicles, marine applications, and performance builds. The electric fuel level sensor detects tank capacity in real time, while the voltmeter function monitors charging system health and battery condition—critical data for diagnosing electrical issues before they strand a vehicle. The digital CB Series architecture ensures precise readings without the needle flutter typical of analog instruments, providing clear visibility in bright sunlight or low-light conditions.

Ideal for truck owners, off-road enthusiasts, and fleet operators who require continuous fuel and electrical system monitoring, this combination gauge eliminates the need for dual-gauge installations and simplifies wiring complexity. AutoMeter's Elite digital series is engineered for reliability in harsh conditions, making it a practical choice for vehicles operating in remote areas, extreme climates, or high-vibration environments where instrument accuracy directly impacts operational confidence and safety decisions.

Weighing 0.55 lbs and measuring 4.6 x 4.5 x 4.8 inches, the AutoMeter 6709-CB integrates seamlessly into existing dashboard layouts. The digital display offers immediate, unambiguous readings—essential when split-second fuel and voltage information impacts route planning, load calculations, or electrical troubleshooting in field conditions.
