2-1/16 Cobalt Voltmeter Gauge

The 2-1/16 Cobalt Voltmeter Gauge by AUTOMETER is an essential instrument for any serious automotive technician or performance enthusiast who demands real-time electrical system monitoring. Whether you're diagnosing charging system issues, tuning a custom build, or simply maintaining peace of mind during long highway runs, this gauge delivers precise voltage readings directly to your line of sight. Built to withstand the rigors of shop work and street duty alike, the Cobalt series represents AUTOMETER's commitment to accuracy and durability in aftermarket instrumentation.

The 2-1/16-inch face design fits seamlessly into most dashboard pod installations or custom gauge clusters without requiring extensive modification to your vehicle's interior. AUTOMETER's Cobalt voltmeter uses a precision analog movement calibrated to measure system voltage across the full operating range of modern automotive electrical systems, typically 8 to 18 volts. The bright, easy-to-read dial with clear graduated markings ensures you can spot voltage anomalies—such as alternator undercharging or parasitic draw conditions—at a glance, even in direct sunlight or poor lighting conditions common to workshop environments.

This gauge is ideal for vintage restorations, street rods, truck builds, and any vehicle where factory instrumentation is absent or unreliable. Mechanics and tuners rely on accurate voltage data to validate alternator performance, verify charging circuit integrity, and troubleshoot electrical gremlins that voltmeters struggle to pinpoint. The compact 4.6 x 4.5 x 4.8-inch footprint and lightweight 0.45 lb construction make it simple to integrate into existing gauge panels or retrofit installations without adding significant weight or complexity to your setup.
