Spek-Pro Voltmeter Gauge 0-16 Volt 2-1/16

The Spek-Pro Voltmeter Gauge 0-16 Volt 2-1/16 by AutoMeter is an essential electrical system monitoring instrument designed for automotive enthusiasts, technicians, and vehicle builders who need precise real-time voltage diagnostics. This compact gauge fits seamlessly into factory or custom dash panels, providing critical visibility into alternator output, battery health, and charging system performance. Whether you're troubleshooting electrical gremlins, monitoring a high-performance build, or maintaining fleet vehicles, this voltmeter delivers the accuracy and reliability demanded by professionals.

AutoMeter's Spek-Pro series combines professional-grade analog instrumentation with durable, weather-resistant construction rated for 0–16 volt measurement across standard automotive electrical systems. The 2-1/16 inch diameter bezel mounts directly into standard gauge pods or custom installations, while the precision needle movement responds immediately to voltage fluctuations, allowing you to catch charging system failures, parasitic drain, or alternator underperformance before they strand you roadside. The gauge's internally regulated design compensates for common electrical noise, ensuring stable readings even in vehicles with aftermarket electronics or high-output ignition systems.

This voltmeter is ideal for 12-volt and 24-volt vehicle architectures and integrates seamlessly with street rods, trucks, race vehicles, and restoration projects where factory instrumentation is absent or unreliable. Installation requires only a 12-volt ignition source and ground connection; detailed wiring instructions ensure quick, professional mounting in aftermarket gauge clusters, pillar pods, or dash panels. Backed by AutoMeter's reputation for precision instrumentation, the Spek-Pro Voltmeter Gauge 0-16 Volt 2-1/16 is the trusted choice for anyone who demands accurate electrical diagnostics at a glance.
